根因分析

传入的HTTP请求体超过服务器允许的最大大小，通常是由于缺少MaxBytesReader或服务器配置所致。

English

The incoming HTTP request body exceeds the server's maximum allowed size, often due to missing MaxBytesReader or server configuration.

解决方案

  1. 95% 成功率 
    r.Body = http.MaxBytesReader(w, r.Body, 10<<20) // 10 MB limit
  2. 80% 成功率 
    if r.ContentLength > maxSize {
    http.Error(w, "Request body too large", http.StatusRequestEntityTooLarge)
    return
}

无效尝试

常见但无效的做法:

  1. 90% 失败

    ReadBufferSize is not related to body size limits and will not prevent the error.

  2. 50% 失败

    Simply increasing the limit may allow denial-of-service attacks.
