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
(相关推荐:nginx教程)
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; .... }
