根因分析
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。
English
The HTTP response body exceeds the maximum allowed size, typically due to server sending large data without proper limits.
解决方案
-
95% 成功率 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 */ }
无效尝试
常见但无效的做法:
-
Reading entire body into memory
80% 失败
May cause out-of-memory; use io.LimitReader.
