Reading from an HTTP response body that has already been closed, often due to premature close or double close.

generic

中文

从已关闭的HTTP响应体中读取，通常由于过早关闭或重复关闭。

Workarounds

  1. 95% success Always defer close after checking error 
    resp, err := http.Get(url)
if err != nil { return err }
defer resp.Body.Close()
// read resp.Body
