【Nginx】解决413错误_nginx 413-优快云博客

本文链接：https://blog.youkuaiyun.com/MacwinWin/article/details/126776094

项目在尝试通过接口上传Excel文件时遇到413错误，这是由于nginx配置中client_max_body_size默认限制为1MB，超过了此限制的请求将被拒绝。日志显示客户端试图发送的数据大小远超限制。解决方案是调整nginx配置文件，增大允许的最大请求体大小，例如设置为20M。完成修改后，需重启nginx服务使配置生效。

原因分析：

众所周知，413含义是“Request Entity Too Large”
nginx 配置文件中的client_max_body_size是控制请求body的大小限制的参数，默认为1MB，如果超过这个数值，则会直接返回413状态码
在这里插入图片描述

解决方案：

修改nginx配置文件

http {
    ...
    client_max_body_size 20M;
}
