# ADR 0001: LCD Expression and Presentation Ownership
## Status
Accepted
## Context
LCD behavior now needs multiple reusable expressions that can be triggered by
different runtime conditions. The system must keep semantic expression ownership
separate from low-level LCD playback so future expressions can be added without
copying cross-layer contracts or coupling orchestration code to asset paths.
## Decision
- `domain` owns LCD expression semantics and declares `domain_expression_*` in
`components/domain/include/domain.h`.
- `control_plane` owns trigger policy: it decides when a runtime condition
requests a semantic expression.
- `platform` owns LCD presentation playback primitives and declares
`platform_lcd_presentation_*` in `components/platform/include/platform.h`.
- Domain runtime adapters map semantic expressions to platform presentation
requests.
- Platform LCD internals serialize presentation requests and perform all LVGL
object mutation inside the LCD render task.
## Consequences
- Adding a new expression requires a domain expression ID and catalog mapping,
plus an optional control-plane trigger rule.
- Public upper-layer facades must not expose platform playback types.
- Platform public APIs must not expose domain semantic expression IDs.
- High-priority expressions can interrupt lower-priority presentations without
leaking policy logic into the LCD driver.

# ADR 0002: Daily Fortune Contract Ownership
## Status
Accepted
## Context
The device needs to receive a user birth profile over its LAN configuration
page, persist it, fetch a daily fortune after wall-clock
synchronization, and apply the returned wealth direction. This workflow crosses
transport, storage, domain data, and orchestration boundaries.
## Decision
- `platform` owns opaque persistent blob storage, SNTP time synchronization,
and bounded raw LAN HTTP transport primitives.
- `domain` owns the typed birth-profile and daily-fortune result contracts,
persistence adapters, direction-name aliases, and user configuration routes.
- `control_plane` owns HTTP fetch, retry, local-midnight scheduling, result
refresh policy, configuration-server connectivity lifecycle, and the
wealth-direction apply sequence.
- `app_composition` continues to start the existing control-plane runtime worker
set and does not gain fortune policy logic.
- The favorable-color element is persisted and logged. LCD color presentation
is deferred because it requires a separate semantic expression contract and
assets.
## Consequences
- The stateless server can be called every day because the device retains the
birth profile in NVS through an opaque platform storage API.
- Upper layers do not include platform types or call platform LCD primitives.
- Cardinal server values such as `正北` are normalized by the domain direction
catalog rather than by orchestration code.
- Any future favorable-color animation requires a new ADR or an explicit update
to the existing LCD expression ownership decision.

# ADR 0003: LAN User Configuration Transport and Lifecycle
## Status
Accepted
## Context
The browser-based birth-profile workflow previously depended on Web Bluetooth
and an externally hosted page. It must instead run from the ESP32 and be
reachable by devices on the same local network.
## Decision
- Remove the BLE provisioning transport and Web Bluetooth utility.
- Retain the existing `TQ-EYE` SoftAP portal only for initial Wi-Fi setup.
- `platform` owns a bounded raw HTTP server contract, socket worker lifecycle,
mDNS publication, request limits, and deterministic stop fallback.
- `domain` owns the embedded page, `/api/profile` and `/api/fortune` semantics,
validation, persistence calls, and mapping to platform HTTP types.
- `control_plane` starts the domain web service while STA is connected, stops
it on disconnect or runtime shutdown, and retries start after reconnect.
- The service is plain HTTP without authentication and is intended only for a
trusted LAN. It is advertised as `tq-cat.local` and logs the DHCP address.
## Consequences
- Browsers no longer need Web Bluetooth support or a separately hosted page.
- User information is readable and writable by any client on the same LAN.
- SoftAP and LAN pages remain separate, so the vendored Wi-Fi portal does not
need project-specific user-profile semantics.
- A future authentication or HTTPS requirement needs a separate decision and
credential lifecycle design.

# ADR 0004: Device Auth Persistence Port Ownership
## Status
Accepted
## Context
Device authentication persists long-lived key material and runtime JWT/backoff
state. The bytes are meaningful only to the authentication policy, but the
storage location also needs legacy migration names and must stay off the
generic platform key/value API at upper layers.
## Decision
- `platform` owns only opaque blob key/value primitives and NVS mechanics.
- `domain` owns the narrow auth persistence port: the public auth record slot
enum, mapping to storage namespaces/keys, legacy migration target names, and
atomic load/save adapter.
- `control_plane` owns the serialized auth key/state schemas, challenge/response
policy, JWT refresh policy, retry/backoff state transitions, and factory
rotation behavior.
- Upper layers must not call generic storage adapters for auth records. They
must use `domain_runtime_auth_store_load_record()` and
`domain_runtime_auth_store_save_record()`.
## Consequences
- Auth persistence has one facade declaration without exposing platform storage
types to `control_plane`.
- Changing the serialized record layout remains a `control_plane` migration
concern.
- Changing NVS namespace/key migration names remains a `domain` adapter concern.
- A future secure-element or encrypted-storage backend can replace the platform
blob primitive without changing auth policy contracts.

# DeviceFortuneController API
## Overview
| Item | Value |
| --- | --- |
| Service module | `token` |
| Controller | `com.talkingq.controller.DeviceFortuneController` |
| Purpose | Generate Four Pillars, Five Elements, daily favorable color, and daily wealth direction from the device ID, birth time, and birthplace |
| Endpoint | `POST /token/api/device/fortune/daily-wealth` |
| Content type | `application/json` |
| Response envelope | `AjaxResult`, always containing `code` and `message`, with `data` on successful responses that contain results |
The complete path through the gateway is normally:
```text
POST https://gz.api.talkingq.com/token/api/device/fortune/daily-wealth
```
When connecting directly to the token service, use its deployed port, for example:
```text
POST http://localhost:8095/token/api/device/fortune/daily-wealth
```
## Endpoint Behavior
### Generate Daily Fortune Data
```http
POST /token/api/device/fortune/daily-wealth
```
The device submits the user's birth year, month, day, hour, minute, and birthplace. The service returns:
- Device ID
- Four Pillars of Destiny
- Five Elements attribute
- Daily favorable color
- Daily wealth direction
Behavior:
- The Four Pillars and Five Elements remain stable for the same birth data.
- The favorable color and wealth direction are calculated for the target date. Results remain stable for the same device, birth data, and date.
- The birthplace participates in the calculation. It is matched to built-in province or city coordinates and used to adjust the birth time to local solar time.

"message": "出生地点不能为空"
}
```
### Missing Device ID
```json
{
"code": 500,
"message": "deviceId不能为空"
}
```
### Invalid Birth Date
For example, `birthYear=2026`, `birthMonth=2`, and `birthDay=30`:
```json
{
"code": 500,
"message": "birthYear/birthMonth/birthDay不是有效日期"
}
```
### Invalid Birth Time
For example, `birthHour=25` or `birthMinute=80`:
```json
{
"code": 500,
"message": "birthHour/birthMinute不是有效时间"
}
```
### Invalid Target Date
```json
{
"code": 500,
"message": "targetDate格式不正确，应为yyyy-MM-dd"
}
```
### Invalid Time Zone
```json
{
"code": 500,
"message": "timezone格式不正确"
}
```
### Unsupported Birthplace
```json
{
"code": 500,
"message": "暂不支持该出生地点，请传入省份或主要城市名称"
}
```
### Unsupported Day Boundary Mode
```json
{
"code": 500,
"message": "dayBoundaryMode仅支持midnight或zi_hour_23"
}
```
## Supported Birthplaces
The implementation uses a built-in keyword list covering major Chinese provinces, municipalities, provincial capitals, important cities, Hong Kong, Macau, and Taiwan. Prefer the following input format:
```text
Province + city
```
Examples:
```text
广东省广州市
广东省深圳市
北京市
上海市
四川省成都市
浙江省杭州市
福建省厦门市
香港
澳门
台湾
```
An unmatched birthplace returns:
```text
暂不支持该出生地点，请传入省份或主要城市名称
```
## Test Coverage
| Test class | Coverage |
| --- | --- |
| `DeviceFortuneControllerTest` | Stable results for fixed birth data and date; daily results can change across dates; missing birthplace returns an error; client time zone does not change Four Pillars after birthplace adjustment. |
| `DeviceFortuneControllerRandomReportTest` | Generates random birth data, verifies `code=200`, and verifies that two consecutive calls with the same request return identical `data`. |
The existing random test report is:
```text
token/daily_wealth_interface_random_test_report.md
```
## Notes
- The response field names are currently Chinese: `设备id`, `生辰八字`, `五行属性`, `今日喜色`, and `今日财位`.
- `currentResidence` and `mbti` are reserved request fields and are not currently used.
- `今日喜色` returns a Five Elements name rather than a literal color. The business mapping is: metal (`金`) = white, wood (`木`) = green, water (`水`) = black, fire (`火`) = red, and earth (`土`) = yellow.
- When `targetDate` is omitted, the server uses its current date and the request time zone. Specify `targetDate` for deterministic device behavior and automated testing.

# LCD Expressions
This document describes how LCD expressions are owned, requested, played, and
extended.
## Ownership Model
LCD expressions are split into semantic intent and low-level playback:
- `control_plane` decides when an expression should be requested.
- `domain` owns semantic expression IDs and maps them to playback requests.
- `platform` owns LCD presentation primitives and LVGL playback.
Do not bypass this path from upper layers. The expected flow is:
```text
control_plane condition
-> domain_runtime_request_expression()
-> platform_lcd_request_presentation()
-> LCD render task / LVGL
```
`control_plane` must not call `platform_lcd_*` APIs directly. `platform` must
not expose domain expression IDs.
## Current Expressions
| Domain expression | Trigger owner | Playback kind | Behavior |
| --- | --- | --- | --- |
| `DOMAIN_EXPRESSION_IDLE` | LCD startup / restore path | `PLATFORM_LCD_PRESENTATION_IDLE` | Shows the default cat idle screen. |
| `DOMAIN_EXPRESSION_SERVER_ERROR` | Multimodal server failure events | `PLATFORM_LCD_PRESENTATION_ASSET_SEQUENCE` | Plays `server_error` for 5 cycles, then returns to idle. |
| `DOMAIN_EXPRESSION_SLOT_REELS` | Slot feature switch worker | `PLATFORM_LCD_PRESENTATION_SLOT_REELS` | Plays the procedural slot reels presentation. |
| `DOMAIN_EXPRESSION_WIFI_DISCONNECTED` | Wi-Fi state monitor worker | `PLATFORM_LCD_PRESENTATION_ASSET_SEQUENCE` | Loops `wifi_disconnected` while STA is unavailable; saved credentials are retried with backoff, then idle is restored after reconnect. |
| `DOMAIN_EXPRESSION_WEALTH_SPIN` | Model-command direction worker | `PLATFORM_LCD_PRESENTATION_ASSET_SEQUENCE` | Plays `spin` exactly twice as a fixed intro while the cat stays still; the worker blocks until it completes, then the reveal and motor rotation start together. |
| `DOMAIN_EXPRESSION_WEALTH_DIRECTION` | Model-command direction worker | `PLATFORM_LCD_PRESENTATION_ASSET_SEQUENCE` | Plays the matched direction's reveal once, then returns to idle. Parametric on `direction_index`; the asset directory is resolved from the domain direction catalog order. |
Server error currently triggers only from:
- `CONTROL_PLANE_MULTIMODAL_EVENT_TASK_FAILED`
- `CONTROL_PLANE_MULTIMODAL_EVENT_OUTPUT_ERROR`
Server error expression requests are suppressed while Wi-Fi STA is disconnected;
the Wi-Fi disconnected expression owns that state because server reachability is
not meaningful without Wi-Fi connectivity.
Transport disconnect/error events are not server error expressions.
## Asset Management
Expression assets live under:
```text
components/platform/assets/lvgl_animations/<asset_dir>/
```
The platform build copies all `.bin` files under this tree into the `gifpack`
LittleFS partition while preserving relative directories. Runtime LVGL paths are
resolved as:
```text
A:/littlefs/<asset_dir>/<file>.bin
```
Asset rules:
- Use LVGL `.bin` images compatible with the active LCD color configuration.
- RGB565 LZ4 compressed assets are supported by the existing decoder path when
`LV_BIN_DECODER_RAM_LOAD` and `LV_USE_LZ4` are enabled.
- File discovery is lexicographic. Name files with zero-padded numeric suffixes.
- If an expression needs a non-linear playback sequence, define `frame_order` in
the domain catalog instead of duplicating files.
- Keep `asset_dir` names short enough for `PLATFORM_LCD_PRESENTATION_ASSET_DIR_MAX`.
The current server error expression uses:
```text
components/platform/assets/lvgl_animations/server_error/
```
Sorted source frames:
```text
TQ_Cat_Server_Error_0000.bin
TQ_Cat_Server_Error_0001.bin
TQ_Cat_Server_Error_0002.bin
```
Playback order is declared in the domain catalog as:
```c
{0, 1, 2, 1, 0}
```
The Wi-Fi disconnected expression uses:
```text
components/platform/assets/lvgl_animations/wifi_disconnected/
```
Sorted source frames:
```text
TQ_Cat_wifi_disconnected_0000.bin
TQ_Cat_wifi_disconnected_0001.bin
TQ_Cat_wifi_disconnected_0002.bin
TQ_Cat_wifi_disconnected_0003.bin
```
Playback order is declared in the domain catalog as:
```c
{0, 1, 2, 3, 2, 1, 0}
```
The wealth-direction reveal uses one shared spin intro plus one body per
direction:
```text
components/platform/assets/lvgl_animations/spin/ (fixed two-cycle spin intro)
components/platform/assets/lvgl_animations/south/
components/platform/assets/lvgl_animations/southwest/
components/platform/assets/lvgl_animations/west/
components/platform/assets/lvgl_animations/northwest/
components/platform/assets/lvgl_animations/north/
components/platform/assets/lvgl_animations/northeast/
components/platform/assets/lvgl_animations/east/
components/platform/assets/lvgl_animations/southeast/
```
These play all frames in sorted order (`frame_order = NULL`). The direction body
asset is resolved from `direction_index` via `s_wealth_direction_asset_dirs[]` in
`components/domain/src/runtime/domain_runtime_adapters.c`, whose order must match
the direction catalog (`components/domain/src/direction/domain_direction_catalog.c`).
## Requesting Expressions
Use `domain_runtime_request_expression()` from orchestration code:
```c
const domain_expression_request_t request = {
.id = DOMAIN_EXPRESSION_SERVER_ERROR,
.trigger = DOMAIN_EXPRESSION_TRIGGER_SERVER_TASK_FAILED,
};
(void)domain_runtime_request_expression(&request);
```
Trigger IDs should describe why the expression was requested. They are useful
for logs and future policy decisions, but the playback mapping is still owned by
the domain catalog.
Slot reel playback uses the same expression path:
`domain_runtime_request_expression()` with `DOMAIN_EXPRESSION_SLOT_REELS`.
## Playback Scheduling
The platform LCD presentation scheduler is non-blocking:
- Requests are copied at API entry.
- LVGL objects are created, deleted, and mutated only inside the LCD render task.
- Same active or pending requests are coalesced.
- Higher-priority interrupting requests replace the active presentation.
- Lower-priority requests are ignored while a higher-priority presentation is
active or pending.
- Asset-backed expressions are cached after their frames are decoded. The LCD
task preheats the `spin` asset after startup and preheats the selected wealth
direction reveal while the fixed spin intro is playing.
- Preheat requests do not change the active display. They decode incrementally
during the render loop, and playback finishes any remaining decode work
synchronously if a reveal is requested before preheat completes.
Current priorities:
| Presentation | Priority | Interrupts current |
| --- | --- | --- |
| Wi-Fi disconnected / idle restore | `120` | Idle restore interrupts Wi-Fi disconnected. |
| Wealth spin / wealth-direction reveal | `110` | Yes (spin interrupts current; the reveal follows after the spin completes). |
| Server error | `100` | Yes |
| Slot reels | `20` | No |
The wealth spin/reveal pair is requested by the model-command direction worker
(`control_plane_model_command_task`): the spin plays exactly twice as a blocking
intro while the selected reveal is preheated, then the reveal is requested and
the motor rotation starts together. At priority `110` a Wi-Fi-disconnected
screen (`120`) still wins, so the reveal is suppressed while STA is down —
consistent with the server-error suppression rule above.
## Adding a New Expression
Follow this checklist for every new expression:
1. Add a semantic ID to `domain_expression_id_t` in
`components/domain/include/domain.h`.
2. Add a trigger reason to `domain_expression_trigger_t` if the new expression
needs a new trigger source.
3. Add a catalog entry in `components/domain/src/runtime/domain_runtime_adapters.c`.
4. For asset-backed expressions, place `.bin` frames under
`components/platform/assets/lvgl_animations/<asset_dir>/`.
5. If the expression needs a custom frame order, define a static `uint8_t`
frame-order array in the domain adapter and reference it from the catalog.
6. Add or update the `control_plane` rule that creates
`domain_expression_request_t`.
7. Build with ESP-IDF v5.5.3 and confirm the LittleFS image includes the asset
directory.
Do not add one-off APIs such as `domain_runtime_show_happy()` or
`platform_lcd_show_error()`. Keep extension through the expression catalog and
the unified presentation request path.
## Validation Checklist
Before merging expression changes:
- Run `idf.py build` through the repository-approved ESP-IDF activation path.
- Confirm new asset files appear in the `gifpack` build output.
- Verify `control_plane` does not include `platform.h` or call `platform_lcd_*`.
- Verify platform code does not refer to `DOMAIN_EXPRESSION_*`.
- For finite asset sequences, verify completion returns to idle when
`return_to_idle` is set.
- For interrupting expressions, verify the active lower-priority presentation is
cancelled cleanly.
- For wealth-direction playback, verify default -> spin and spin -> reveal
transitions use cached/preheated assets without visible transition stalls.

# LVGL + GIF Reproduction Guide (ESP-IDF Project 1:1 Porting)
This document tracks how to reproduce the `LVGL + ST7789V + GIF` runtime path in this repository, and records what is already implemented versus what is still missing.
All claims should be traceable to file:line evidence. If evidence is not available in the repository, mark it as `UNKNOWN`.
## Section 0: Current Implementation Status (2026-03-12)
This section reflects the actual state of the repository and takes precedence over older assumptions.
### 0.1 Scope approved in this round
- Introduce LVGL using `lvgl/lvgl = 9.2.0`.
- Use a single ST7789V panel.
- Do not use shared SPI for multiple LCD panels.
- Follow LCD GPIO mapping from `docs/gpio-map.md`.
- Keep layered architecture unchanged: `app_composition -> control_plane -> domain -> platform`.
### 0.2 Completed progress
1. LVGL dependency was added and locked to `9.2.0`.
Evidence: `main/idf_component.yml:3`, `dependencies.lock:64`, `dependencies.lock:70`.
2. LCD runtime was migrated from JPEG demo rendering to `esp_lcd + lvgl`.
Evidence: `components/platform/CMakeLists.txt:13`, `components/platform/CMakeLists.txt:49`, `components/platform/CMakeLists.txt:58`, `components/platform/src/lcd.c:367`, `components/platform/src/lcd.c:401`, `components/platform/src/lcd.c:429`, `components/platform/src/lcd.c:543`.
3. Single ST7789V panel path is active.
Evidence: `components/platform/src/lcd.c:2`, `components/platform/src/lcd.c:401`, `components/platform/src/lcd.c:496`.
4. LCD pin mapping matches the GPIO map document.
Evidence: `docs/gpio-map.md:16`, `docs/gpio-map.md:18`, `docs/gpio-map.md:19`, `docs/gpio-map.md:20`, `docs/gpio-map.md:24`, `docs/gpio-map.md:26`, `components/platform/src/lcd.c:35`, `components/platform/src/lcd.c:36`, `components/platform/src/lcd.c:37`, `components/platform/src/lcd.c:38`, `components/platform/src/lcd.c:39`, `components/platform/src/lcd.c:40`, `sdkconfig.defaults:81`.
5. Build passed after integration.
Evidence: local run `idf.py fullclean && idf.py build` completed successfully.
6. No runtime `gc9a01` dependency remains under `components` and `main`.
Evidence: `rg -n "gc9a01|GC9A01" components main` returned no matches.
### 0.3 Still missing
1. GIF business pipeline is not implemented yet in the current codebase.
Missing modules include `components/gifdisplay/*`, GIF package loading, preload, and runtime switching.
2. Emotion-driven GIF switching path is not implemented (`components/emotion/*` is absent).
3. The current LVGL UI is a baseline default screen, not GIF playback UI.
4. Device-side GIF runtime logs are not available yet (`Switching gifs...` class logs are not present in runtime code).
### 0.4 Differences vs the original baseline description
1. Panel topology:
Original baseline: dual GC9A01.
Current implementation: single ST7789V.
2. LVGL version:
Original baseline: `9.4.0`.
Current implementation: `9.2.0` (explicitly requested in this round).
3. Display stack:
Original baseline references an older code layout and line map.
Current repository uses the layered runtime path and a rewritten `components/platform/src/lcd.c` implementation.
4. GIF status:
Original baseline assumes full GIF chain exists.
Current repository does not yet include GIF runtime components.
### 0.5 Environment note
- `AGENTS.md` requires ESP-IDF `5.5.2` setup instructions.
Evidence: `AGENTS.md:31`.
- The actual local verification in this round used ESP-IDF `5.5.1` because that environment path exists locally.
Evidence: `dependencies.lock:63`.
## Section A: Reality Check + Runtime Call Graph (Current Repository)
### A.1 Reality Check
1. LVGL runtime path is now present in production LCD code (not only a test utility).
Evidence: `components/platform/src/lcd.c:415`, `components/platform/src/lcd.c:429`, `components/platform/src/lcd.c:479`, `components/platform/src/lcd.c:543`.
2. GIF playback path is not present in runtime code.
Evidence: `rg -n "gifdisplay|lv_gif|gifpack" components main` has no runtime hits.
3. `app_main` still starts LCD through layered interfaces.
Evidence: `main/main.c:285`, `components/app_composition/src/app_composition_runtime_support.c:65`, `components/control_plane/src/control_plane_runtime_support.c:39`, `components/domain/src/domain_runtime_support.c:39`, `components/platform/src/platform_runtime_support.c:176`.

## Section C: GIF Pipeline Status
### C.1 Current status
- `UNKNOWN` as implemented feature in this repository branch: full GIF runtime pipeline.
- No `gifdisplay` component exists in current source tree.
- No `emotion` component exists in current source tree.
### C.2 Required future implementation (not done yet)
1. Add GIF runtime owner component (recommended: `components/gifdisplay`).
2. Add GIF asset packaging and partition-read path.
3. Add GIF widget playback path in LVGL (`lv_gif_set_src` or equivalent strategy).
4. Add business trigger path from runtime state to GIF switching.
5. Add startup preload / timeout / rollback strategy consistent with target behavior.
## Section D: Layering and Dependency Compliance
Current layered dependency chain remains valid:
- `app_composition` depends on `control_plane`.
Evidence: `components/app_composition/CMakeLists.txt:11`.
- `control_plane` depends on `domain`.
Evidence: `components/control_plane/CMakeLists.txt:13`.
- `domain` depends on `platform`.
Evidence: `components/domain/CMakeLists.txt:13`.
- `platform` owns runtime LCD integration directly (no separate `lcd` component dependency).
Evidence: `components/platform/CMakeLists.txt:13`, `components/platform/src/platform_runtime_support.c:11`, `components/platform/src/platform_runtime_support.c:176`.
## Section E: Verification Matrix
### E.1 Completed in this round
| Check | Command | Result |
|---|---|---|
| Build | `idf.py fullclean && idf.py build` | Passed |
| LVGL dependency | lockfile inspection | `lvgl/lvgl = 9.2.0` |
| GC9A01 runtime residue | `rg -n "gc9a01|GC9A01" components main` | No matches |
### E.2 Pending for next round
| Check | Command | Expected |
|---|---|---|
| Device runtime LVGL stability | `idf.py -p <PORT> flash monitor` | No frequent flush/panel failures |
| GIF startup and switching | Same monitor run with GIF triggers | GIF load and switching logs present |
| Long-run behavior | Continuous run test | Stable memory and frame updates |
## Section F: Risks and Open Items
1. The guide originally describes a complete GIF stack, but the current repository does not include those modules yet.
2. The current implementation is LVGL-base-only; GIF behavior parity is still pending.
3. Environment parity risk exists if strict ESP-IDF `5.5.2` compliance is mandatory.
4. Performance targets (FPS/CPU/memory thresholds) are not yet defined in code-level acceptance criteria.
## Section G: Minimal File Set (Current State)
Implemented in this round:
- `main/idf_component.yml`
- `dependencies.lock`
- `components/platform/CMakeLists.txt`
- `components/platform/internal/lcd.h`
- `components/platform/src/lcd.c`
Not yet implemented but required for full GIF parity:
- `components/gifdisplay/*`
- `components/emotion/*`
- GIF assets and packaging scripts

本文介绍基于 WebSocket 协议的实时多模态交互 API。WebSocket协议延迟低、资源占用少，是首选接入方案。
WebSocket是一种支持全双工通信的网络协议。客户端和服务器通过一次握手建立持久连接，双方可以互相主动推送数据，因此在实时性和效率方面具有显著优势。
对于常用编程语言，有许多现成的WebSocket库和示例可供参考，例如：
- Go：`gorilla/websocket`
- PHP：`Ratchet`
- Node.js：`ws`
建议您先了解WebSocket的基本原理和技术细节，再参照本文进行开发。
**说明**
对于RTOS或某些旧版Linux系统，建立安全Websocket 通信所依赖的 TLS 隧道，需要做如下配置：
- TLS 版本要求 TLS1.2 或以上
- 开启 SNI（SERVER NAME INDICATION）
- 配置 CA 证书（[GlobalSign Root CA - R3](https://secure.globalsign.net/cacert/Root-R3.crt)）（也可至GlobalSign官网下载）
## **前提条件**
已开通服务并[获取API Key](https://help.aliyun.com/zh/model-studio/get-api-key)。请[配置API Key到环境变量](https://help.aliyun.com/zh/model-studio/configure-api-key-through-environment-variables)，而非硬编码在代码中，防范因代码泄露导致的安全风险。
**说明**
对于客户端调用的场景，在客户端处理API Key有安全风险，建议从服务端用API Key获取临时鉴权Token，再把Token下发给客户端使用。具体方法请参考：[生成临时API Key](https://help.aliyun.com/zh/model-studio/generate-temporary-api-key)。
## **调用时序图**
**\[关键流程\]** 服务端返回`Started`消息表示会话创建成功，但客户端**禁止**立即发送音频。客户端必须等待并接收到`DialogStateChanged`事件且`state`为`Listening`后，方可开始发送音频流。
![image](https://help-static-aliyun-doc.aliyuncs.com/assets/img/zh-CN/8963248471/p958632.png)
## **服务地址**
```
wss://dashscope.aliyuncs.com/api-ws/v1/inference
```
## **鉴权**
需要在发起初始的WebSocket握手（HTTP Upgrade）请求时，把API Key放在HTTP Header里（需要将your\_api\_key替换为真实的API Key）：
```
"Authorization": "Bearer your_api_key"
```
## **语音交互**
多模态交互应用开启了**语音交互**后，支持语音识别和语音合成。
语音识别支持的模型包括：[Paraformer实时语音识别](https://help.aliyun.com/zh/model-studio/paraformer-real-time-speech-recognition-api-reference/)（Paraformer），[FUN-ASR实时语音识别](https://help.aliyun.com/zh/model-studio/fun-asr-real-time-speech-recognition-api-reference/)（FunASR），[千问3-ASR-Flash-Realtime](https://help.aliyun.com/zh/model-studio/real-time-speech-recognition-user-guide)（qwen3-asr-flash-realtime），多模态交互轻量版语音识别（AppSpecificASR-Realtime）。
语音合成支持的模型包括：[语音合成CosyVoice-v2大模型](https://help.aliyun.com/zh/model-studio/cosyvoice-large-model-for-speech-synthesis/)（cosyvoice-v2），[语音合成CosyVoice-v3-Flash大模型](https://help.aliyun.com/zh/model-studio/text-to-speech)（cosyvoice-v3-flash），[语音合成CosyVoice-v3-plus大模型](https://help.aliyun.com/zh/model-studio/text-to-speech)（cosyvoice-v3-plus），[语音合成CosyVoice-v3.5-Flash大模型](https://help.aliyun.com/zh/model-studio/text-to-speech)（cosyvoice-v3.5-flash），[语音合成CosyVoice-v3.5-Plus大模型](https://help.aliyun.com/zh/model-studio/text-to-speech)（cosyvoice-v3.5-plus），[千问3-TTS-Flash-Realtime](https://help.aliyun.com/zh/model-studio/realtime-tts-user-guide)（qwen3-tts），[千问3-TTS-Instruct-Flash-Realtime](https://help.aliyun.com/zh/model-studio/realtime-tts-user-guide)（qwen3-tts-instruct），[千问3-声音设计](https://help.aliyun.com/zh/model-studio/qwen-tts-voice-design)（qwen3-tts-vd），[千问3-声音复刻](https://help.aliyun.com/zh/model-studio/qwen-tts-voice-cloning)（qwen3-tts-vc），[Sambert语音合成](https://help.aliyun.com/zh/model-studio/sambert-speech-synthesis/)（sambert），多模态交互轻量版语音合成（AppSpecificTTS）。
语音合成支持的音色，可以在控制台上选择了模型后，点击右侧语音交互体验区域的右上角查看音色列表。
官方音色也可以参考官方文档：cosyvoice-v2 / cosyvoice-v3-plus / cosyvoice-v3-flash 支持的官方音色参考[音色列表](https://help.aliyun.com/zh/model-studio/cosyvoice-voice-list)，qwen3-tts 支持的官方音色参考[支持的音色](https://help.aliyun.com/zh/model-studio/realtime-tts-user-guide#422789c49bqqx)，sambert支持的音色参考[模型列表](https://help.aliyun.com/zh/model-studio/sambert-java-sdk#74cedcb97el0b)（去掉开头的"sambert-"和末尾的"-v1"后就是voice的取值）。
使用复刻音色时，确认复刻音色状态为"OK"后才能使用。查询方法参考[查询特定音色](https://help.aliyun.com/zh/model-studio/cosyvoice-clone-design-api#34490e5a2by7z)。
## **消息类型**
### **二进制消息（Binary Message）**
当前二进制消息仅包含音频数据。
#### **上传音频**
上传音频时，将原始音频直接转为二进制流即可，无需额外处理。
上传的语音识别音频需满足：16bit（采样位深）、单声道、有符号、little-endian PCM编码，采样率参考[Start](#5b2363d40585y)消息的参数parameters.upstream.sample\_rate的取值说明。
如果希望减少网络流量和带宽占用，用户可以把PCM音频编码为Opus格式，同时设置上传音频格式为raw-opus。
上传音频时，根据[Start](#5b2363d40585y)消息中`upstream.mode`设置不同，采取的措施也不同：
- mode为 `tap2talk` 或 `duplex`：客户端需持续上传音频，服务端自动检测语音活动。建议每100ms上传一次数据，间隔太长或太短会对延时和处理效率造成负面影响。
- 音频上传速率计算公式：`数据每次上传的字节数 = 采样率 * 采样位深/8 * 时间间隔（ms）/ 1000`
- 以16kHz采样率、16bit位深、100ms间隔为例，每次应上传 `16000 * (16/8) * 100 / 1000 = 3200` 字节的PCM数据。
- mode为 `push2talk`：客户端无需持续上传音频，但需通过[SendSpeech](#cec23c1556u8x)和[StopSpeech](#d11933e7b5jz0)通知服务端音频识别的开始和结束。发送[SendSpeech](#cec23c1556u8x)后需立即上传音频，否则会增加处理时间。
#### **下发音频**
服务端将大模型回复发送至TTS生成语音然后下发给客户端：
- 下发音频为16bit单声道，采样率和编码由[Start](#5b2363d40585y)消息参数定义。
- 下发速度取决于TTS服务性能，通常快于播放速度。
- 音频下发前发送[RespondingStarted](#0693e9d4a5f91)事件；结束后发送[RespondingEnded](#402cbee340r1m)事件。
- 客户端需在播放完成后上报[LocalRespondingEnded](#f4b1a6bf22ymq)，通知服务端播放结束。
### **文本消息（Text Message）**
文本消息是JSON格式字符串，按传递方向分为两类：
- **输入消息（Input Message）**：客户端发送给服务端的指令（directive），表示客户端希望服务端执行特定动作。
- **输出消息（Output Message）**：服务端发送给客户端的事件（event），表示服务端动作执行结果或进展。
文本消息标记交互流程的关键节点，控制流程并传输关键信息。通过[时序图](#6d25d6f8ddbtd)可了解不同消息的交互时序。
文本消息包含两部分：`header`和`payload`。
- `payload`：内容随[消息类型](#408ddb268eyt7)变化。
- `header`：内容固定，包含以下参数：
| **参数** | **类型** | **是否必选** | **说明** |
| --- | --- | --- | --- |
| task\\_id | string | 是 | 本次连接唯一标识，用于在工程链路上跟踪任务执行。由客户端生成，格式建议为36位uuid字符串，格式示例："f894c16f-f20e-4c1d-837e-89e0fbc63a43" |
| streaming | string | 是 | 输入输出类型，对于多模态交互必须为 "duplex" ，表示流式输入，流式输出 |
| action | string | 是 | 模型输入消息类型： - run-task: 任务的第一个输入消息 - finish-task: 任务的最后一个输入消息 - continue-task: 任务中其他输入消息 |
## **连接保活策略**
百炼平台规定，如果在**任意连续的60秒内**服务端没有向客户端发送任何消息，则认为调用发生错误，WebSocket连接将被服务端主动断开并返回`ResponseTimeout`错误。
若客户端需在无交互时保持连接，应定期发送心跳消息（HeartBeat）。服务端会回应心跳，确保连接活跃，避免超时关闭。
移动端和C++ SDK已内置心跳保活逻辑，用户无需手动发送。
## **文本消息类型**
