Root Cause

The HTTP response body exceeds the maximum allowed size, typically due to server sending large data without proper limits.

generic

中文

HTTP响应体超过允许的最大大小，通常由于服务器发送大量数据而未设置适当限制。

Workarounds

  1. 95% success Use io.LimitReader to cap response size 
    maxSize := int64(10 << 20) // 10 MB
body, err := io.ReadAll(io.LimitReader(resp.Body, maxSize))
if err != nil { return err }
if int64(len(body)) == maxSize { /* handle truncation */ }

Dead Ends

Common approaches that don't work:

  1. Reading entire body into memory 80% fail

    May cause out-of-memory; use io.LimitReader.
