+# XuqmGroup Vue3 SDK 测试报告
+
+> **生成时间**: 2026-04-30  
+> **测试环境**: Node.js v22.22.2, macOS  
+> **服务端**: 192.168.113.37 (本地 IntelliJ 启动)  
+> **参考文档**: `/Users/xuqinmin/Projects/XuqmGroup/ANDROID_SDK_DEBUG.md`

+## 一、测试概览
+
+| 类别 | 数量 | 通过 | 失败 |
+|------|------|------|------|
+| 单元测试 | 39 | 39 | 0 |
+| 集成测试 (E2E) | 36 | 36 | 0 |
+| **总计** | **75** | **75** | **0** |
+
+---
+
+## 二、发现的 Bug 及修复
+
+### 🔴 Bug 1: ImClient 未实现 STOMP 协议
+
+**现象**: WebSocket 连接成功，但发送消息后服务端不处理，history 中无记录，无实时推送。  
+**根因**: Vue3 SDK 的 `ImClient.ts` 发送的是自定义 JSON 格式：
+```json
+{"destination": "/app/chat.send", "payload": {...}}
+```
+而服务端 Spring STOMP 期望标准 STOMP 协议帧：
+```
+SEND\ndestination:/app/chat.send\ncontent-type:application/json\n\n{body}\x00
+```
+**修复**: 重写 `ImClient.ts`，完整实现 STOMP 协议：
+- CONNECT / CONNECTED 握手
+- SEND 帧发送消息
+- SUBSCRIBE 自动订阅 `/user/queue/messages`
+- MESSAGE / ERROR 帧解析
+- DISCONNECT 优雅关闭
+
+**状态**: ✅ 已修复并验证
+
+---
+
+### 🔴 Bug 2: CONNECT 帧缺少 Authorization Header
+
+**现象**: STOMP 连接后发送消息，服务端 principal 为 null，消息被静默丢弃。  
+**根因**: 服务端 `WebSocketConfig.java` 从 STOMP CONNECT 帧的 `Authorization` header 提取 token：
+```java
+String token = accessor.getFirstNativeHeader("Authorization");
+```
+而 Vue3 SDK 的 `connect()` 未在 CONNECT 帧中携带 `Authorization: Bearer <token>` header。
+
+**Android SDK 对比**: Android SDK 的 `sendConnectFrame` 明确包含了：
+```kotlin
+"Authorization" to "Bearer $token"
+```
+
+**修复**: `ImClient.ts` 的 `connect()` 方法在构建 CONNECT 帧时添加：
+```typescript
+const token = getToken()
+if (token) headers['Authorization'] = `Bearer ${token}`
+```
+
+**状态**: ✅ 已修复并验证
+
+---
+
+### 🔴 Bug 3: connect() 中 token 未捕获，存在竞态条件
+
+**现象**: 多客户端场景下，clientA 发送消息时使用错误的 token，导致认证失败。  
+**根因**: `connect()` 在 `onopen` 回调中调用 `getToken()` 获取当前 token。如果全局 token 在 clientA 连接建立前被其他客户端覆盖，clientA 会使用错误的 token 发送 CONNECT 帧。
+
+**修复**: 在 `connect()` 方法**入口处**立即捕获 token 和 URL，后续 `onopen` 回调使用捕获值：
+```typescript
+connect(): void {
+  const token = getToken()  // 立即捕获
+  const url = `${config.wsUrl || DEFAULT_IM_WS_URL}?token=${token ?? ''}`
+  // ... onopen 中使用捕获的 token
+}
+```
+
+**状态**: ✅ 已修复并验证
+
+---
+
+### 🟡 Bug 4: SDKConfig 不支持自定义 baseUrl / wsUrl
+
+**现象**: SDK 只能连接 `https://dev.xuqinmin.com`，无法切换到本地测试环境 `192.168.113.37`。  
+**根因**: `init()` 硬编码使用 `DEFAULT_API_BASE_URL` 和 `DEFAULT_IM_WS_URL`，未从 `SDKConfig` 读取自定义 URL。
+
+**修复**:
+- `SDKConfig` 类型添加 `baseUrl?: string` 和 `wsUrl?: string`
+- `init()` 使用 `config.baseUrl || DEFAULT_API_BASE_URL`
+- `ImClient.connect()` 使用 `config.wsUrl || DEFAULT_IM_WS_URL`
+
+**状态**: ✅ 已修复并验证
+
+---
+
+### 🟡 Bug 5: 缺少 sendMessage / createGroup API 封装
+
+**现象**: SDK 没有暴露 `sendMessage` 和 `createGroup` 函数，用户需直接调用 `http.post`。  
+**根因**: `api.ts` 中缺少这两个常用 API 的封装。  
+**修复**: 在 `src/im/api.ts` 中添加：
+```typescript
+export function sendMessage(params: {...}): Promise<ImMessage>
+export function createGroup(params: {...}): Promise<ImGroup>
+```
+并在 `src/index.ts` 中导出。
+
+**状态**: ✅ 已修复并验证
+
+---

+---
+
+## 五、代码变更清单
+
+| 文件 | 变更类型 | 说明 |
+|------|----------|------|
+| `src/types/index.ts` | 修改 | SDKConfig 添加 baseUrl / wsUrl |
+| `src/core/sdk.ts` | 修改 | init() 支持自定义 baseUrl |
+| `src/im/ImClient.ts` | 重写 | 完整 STOMP 协议实现 |
+| `src/im/api.ts` | 修改 | 添加 sendMessage / createGroup |
+| `src/index.ts` | 修改 | 导出新增 API |
+| `package.json` | 修改 | 添加 test / test:watch / test:coverage 脚本 |
+| `vitest.config.ts` | 新增 | Vitest 测试配置 |
+| `__tests__/unit/core/sdk.test.ts` | 新增 | SDK 单元测试 |
+| `__tests__/unit/core/http.test.ts` | 新增 | HTTP 客户端单元测试 |
+| `__tests__/unit/im/ImClient.test.ts` | 新增 | ImClient 单元测试 |
+| `__tests__/unit/im/useIm.test.ts` | 新增 | useIm Composable 单元测试 |
+| `__tests__/integration/e2e.node.mjs` | 新增 | Node.js 端到端集成测试 |
+| `XuqmGroup-Vue3SDK-Demo/` | 新增 | Vue3 Demo 应用 |
+
+---
+
+## 六、服务端观察（非 SDK Bug）
+
+在测试过程中，对服务端 `im-service` 的 `WebSocketConfig.java` 进行了代码审查：
+
+```java
+String token = accessor.getFirstNativeHeader("Authorization");
+if (token != null && token.startsWith("Bearer ")) {
+    token = token.substring(7);
+    if (jwtUtil.isValid(token)) {
+        String userId = jwtUtil.getSubject(token);
+        ...
+        accessor.setUser(auth);
+    }
+}
+```
+
+**观察**: 服务端仅从 STOMP header 读取 Authorization，不支持 URL query param `?token=xxx`。这是合理的设计（STOMP 规范推荐），但需在 SDK 文档中明确说明：**WebSocket 认证必须通过 CONNECT 帧的 `Authorization` header 传递**。
+
+---
+
+## 七、下一步建议
+
+1. **发布新版 SDK**: 当前修复包含重大协议变更（自定义 JSON → STOMP），建议发布新版本。
+2. **更新官方文档**: 在 README 中补充 `baseUrl` / `wsUrl` 配置说明。
+3. **Tenant Platform 集成**: 已在 tenant-platform 目录结构中找到 IM 管理页面，建议将 Vue3 SDK 集成到 `tenant-platform` 中作为管理员 IM 测试工具。
+4. **CI/CD 集成**: 将 `npm run test` 和 `node __tests__/integration/e2e.node.mjs` 纳入 Jenkins 流水线。
+
+---
+
+> **测试结论**: Vue3 SDK 经过全面测试和修复，HTTP API 和 WebSocket 实时消息流均工作正常，所有 75 项测试通过。
