nginx上传文件失败,提示上传文件过大,怎么样解决

问题描述:

上传文件失败,文件大小4M左右。上传程序为Java,通过nginx反向代理写入Fastdfs中,但是一直失败,查看nginx错误日志,提示如下内容:

client intended to send too large body: 4134591 bytes

分析:

根据错误信息提示,客户端发送的body过大,nginx默认的客户端body大小为1M。

官方文档如下:

Syntax: client_max_body_size size;
Default: client_max_body_size 1m;
Context: http, server, location
Sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.

解决方法:

根据官方文档说明,可以在nginx配置文件中http、server、location等配置块添加配置,client_max_body_size size;来调整允许的客户端上传文件的body大小。设置为0,表示不限制。

代码示例:

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;
	
    client_max_body_size 100m;
	....
	}
