nginx 客戶端請求大小限制

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.

今天上傳圖片，發現老出錯，也沒超過程序所設的大小限制，爲啥就不行。後來突然想起來以前用nginx接tomcat也出現過，後來證明是nginx默認設置導致的。

在server節點下增加 client_max_body_size 4m; 搞定。nginx 默認限制是1m
