-# SSE工具类使用指南
-
-## 概述
-
-SSE (Server-Sent Events) 工具类提供了通用的流式响应处理功能，支持实时数据流处理、回调机制和错误处理。
-
-## 主要功能
-
-### 1. 基础SSE请求 - `createSSERequest()`
-
-最灵活的底层API，支持完全自定义配置。
-
-```javascript
-import { createSSERequest } from '@/utils/sse.js'
-
-const response = await createSSERequest({
-  url: 'https://api.example.com/stream',
-  method: 'POST',
-  data: { message: '你好' },
-  headers: { 'Custom-Header': 'value' },
-  onChunk: (chunk) => {
-    console.log('接收到数据:', chunk.content)
-    console.log('累积内容:', chunk.totalContent)
-  },
-  onComplete: (result) => {
-    console.log('流式响应完成:', result.data)
-  },
-  onError: (error) => {
-    console.error('发生错误:', error)
-  },
-  doneMarker: '[DONE]' // 自定义结束标记
-})
-```
-
-### 2. 默认配置SSE请求 - `createDefaultSSERequest()`
-
-带有默认配置的便捷API。
-
-```javascript
-import { createDefaultSSERequest } from '@/utils/sse.js'
-
-const response = await createDefaultSSERequest(
-  '/api/chat/stream', // API端点
-  { message: '你好' }, // 请求数据
-  {
-    onChunk: (chunk) => {
-      // 处理数据块
-      updateUI(chunk.content)
-    },
-    onComplete: (result) => {
-      // 处理完成
-      console.log('完成:', result.data.message)
-    }
-  }
-)
-```
-
-### 3. 宠物助手专用SSE - `createPetAssistantSSE()`
-
-专门为宠物助手功能设计的API。
-
-```javascript
-import { createPetAssistantSSE } from '@/utils/sse.js'
-
-const response = await createPetAssistantSSE(
-  {
-    message: '我的宠物生病了怎么办？',
-    temperature: 0.7,
-    maxTokens: 1000
-  },
-  {
-    onChunk: (chunk) => {
-      // 实时更新AI回复
-      aiMessage.content = chunk.totalContent
-      scrollToBottom()
-    },
-    onComplete: (result) => {
-      // 更新元数据
-      aiMessage.isSensitive = result.data.isSensitive
-      aiMessage.tokenCount = result.data.tokenCount
-    }
-  }
-)
-```
-
-### 4. 可取消的SSE请求 - `createCancellableSSE()`
-
-支持取消操作的SSE请求。
-
-```javascript
-import { createCancellableSSE, SSE_STATUS } from '@/utils/sse.js'
-
-const { promise, cancel, getStatus } = createCancellableSSE({
-  url: '/api/stream',
-  data: { message: '长时间处理的请求' },
-  onChunk: (chunk) => {
-    console.log('状态:', getStatus()) // 'streaming'
-    updateContent(chunk.content)
-  }
-})
-
-// 5秒后取消请求
-setTimeout(() => {
-  if (getStatus() === SSE_STATUS.STREAMING) {
-    cancel()
-    console.log('请求已取消')
-  }
-}, 5000)
-
-try {
-  const result = await promise
-  console.log('请求完成:', result)
-} catch (error) {
-  console.log('请求被取消或失败:', error)
-}
-```
-
-## 回调函数参数
-
-### onChunk(chunk)
-- `chunk.content` - 当前数据块内容
-- `chunk.totalContent` - 累积的完整内容
-- `chunk.chunk` - 原始解析的数据对象
-
-### onComplete(result)
-- `result.data.message` - 完整的响应消息
-- `result.data.isSensitive` - 是否包含敏感内容
-- `result.data.tokenCount` - 使用的token数量
-- `result.data.responseTime` - 响应时间
-
-### onError(error)
-- 网络错误、解析错误或其他异常
-
-## 状态枚举
-
-```javascript
-import { SSE_STATUS } from '@/utils/sse.js'
-
-SSE_STATUS.PENDING    // 等待中
-SSE_STATUS.STREAMING  // 流式传输中
-SSE_STATUS.COMPLETED  // 已完成
-SSE_STATUS.ERROR      // 发生错误
-SSE_STATUS.CANCELLED  // 已取消
-```
-
-## 在Vue组件中使用
-
-```javascript
-// 在组件中导入
-import { createPetAssistantSSE } from '@/utils/sse.js'
-
-export default {
-  methods: {
-    async sendMessage() {
-      // 创建消息对象
-      const aiMessage = {
-        type: 'ai',
-        content: '',
-        time: this.getCurrentTime()
-      }
-      this.messageList.push(aiMessage)
-      
-      // 发起SSE请求
-      try {
-        const result = await createPetAssistantSSE(
-          { message: this.inputMessage },
-          {
-            onChunk: (chunk) => {
-              // 实时更新内容
-              aiMessage.content = chunk.totalContent
-              this.$nextTick(() => {
-                this.scrollToBottom()
-              })
-            },
-            onComplete: (result) => {
-              // 更新元数据
-              Object.assign(aiMessage, result.data)
-            },
-            onError: (error) => {
-              console.error('SSE失败:', error)
-              // 可以在这里实现降级处理
-            }
-          }
-        )
-      } catch (error) {
-        // 处理异常
-        this.handleError(error)
-      }
-    }
-  }
-}
-```
-
-## 注意事项
-
-1. **自动认证**: 工具类会自动添加Authorization头部
-2. **错误处理**: 建议同时实现onError回调和try-catch
-3. **内存管理**: 长时间的流式响应注意内存使用
-4. **网络状态**: 考虑网络中断的情况
-5. **降级处理**: SSE失败时可以降级到普通API请求
-
-## 扩展使用
-
-可以基于基础API创建更多专用函数：
-
-```javascript
-// 创建客服聊天SSE
-export function createCustomerServiceSSE(data, callbacks) {
-  return createDefaultSSERequest('/api/customer/stream', data, callbacks)
-}
-
-// 创建代码生成SSE
-export function createCodeGenerationSSE(data, callbacks) {
-  return createDefaultSSERequest('/api/code/generate', data, callbacks)
-}
-```
