nginx 客户端请求大小限制

SYNTAX: client_max_body_size size;DEFAULT:    client_max_body_size 1m;CONTEXT:    http, server, locationSets 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.

今天上传图片，发现老出错，也没超过程序所设的大小限制，为啥就不行。后来突然想起来以前用nginx接tomcat也出现过，后来证明是nginx默认设置导致的。

在server节点下增加 client_max_body_size 4m; 搞定。nginx 默认限制是1m
