|
||
"content": "Hello" // 必需：消息内容
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
#### ❌ 413 Payload Too Large

for (let i = 0; i < text.length; i += maxLength) {
|
||
chunks.push(text.slice(i, i + maxLength));
|
||
}
|
||
return chunks;
|
||
}
|
||
```
|
||
|
||
3. **调整配置（如果有权限）：**

|
||
try {
|
||
return await requestFn();
|
||
} catch (error) {
|
||
if (i === maxRetries - 1) throw error;
|
||
await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)));
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
2. **减少请求复杂度：**
|

1. **检查客户端超时设置：**
|
||
```javascript
|
||
const controller = new AbortController();
|
||
const timeoutId = setTimeout(() => controller.abort(), 60000); // 60秒超时
|
||
|
||
fetch(url, {
|
||
signal: controller.signal,
|
||
// ...其他选项
|
||
});
|
||
```
|
||
|
||
2. **实现重连机制：**
|
||
```javascript
|
||
async function streamWithRetry(url, options, maxRetries = 3) {
|
||
for (let attempt = 0; attempt < maxRetries; attempt++) {
|
||
try {
|
||
const response = await fetch(url, options);
|
||
// 处理流式响应
|
||
return response;
|
||
} catch (error) {
|
||
if (attempt === maxRetries - 1) throw error;
|
||
await new Promise(resolve => setTimeout(resolve, 1000));
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
3. **验证 SSE 格式：**
|
||
```javascript
|
||
// 确保正确解析 SSE 数据
|
||
const lines = chunk.split('\n');
|
||
for (const line of lines) {
|
||
if (line.startsWith('data: ')) {
|
||
const data = line.slice(6);
|
||
if (data === '[DONE]') break;
|
||
// 处理数据
|
||
}
|
||
}
|
||
```
|
||
|
||

-H "Authorization: Bearer $PROXY_KEY" \
|
||
-H "Content-Type: application/json" \
|
||
-d '{
|
||
"model": "deepseek-chat",
|
||
"messages": [{"role": "user", "content": "test"}]
|
||
}' | jq .
|
||
|
||
echo "✅ 健康检查完成"
|
||
```
|
||
|
||
### 4. 性能监控
