## Root Cause

HTTP响应体未关闭，导致连接无法复用，服务器因空闲超时关闭连接，客户端在读取时遇到EOF。

## Workarounds

1. **** (95% success)
   ```
   defer resp.Body.Close()
io.Copy(io.Discard, resp.Body) // 确保读取完所有内容
   ```
2. **** (90% success)
   ```
   使用io.ReadAll或json.Decoder时确保正确关闭响应体。
   ```

## Dead Ends

- **** — 不关闭响应体会导致连接泄漏，最终耗尽连接池。 (95% fail)
- **** — 未读取的响应体可能阻止连接复用，导致性能下降。 (70% fail)
