413 Request Entity Too Large

網上找到是因為設置的問題，想到自己最終是布署在iis上的,找到如下步驟:

1. Launch “Internet Information Services (IIS) Manager”
2. Select the site that you are hosting your web application under it.
3. In the Features section, double click “Configuration Editor”
4. Under “Section” select: system.webServer  then serverRuntime
5. Modify the “uploadReadAheadSize” section to be like 20MB (the value there is in Bytes)
6. Click Apply

按以上步驟設置后，無效,后突然想到中間用了nginx轉發,查看nginx日志,找到錯誤信息

client intended to send too large body: 3127719 bytes

修改配置(增加 client_max_body_size 20m;)

        location / {
            root   html;
            index  index.html index.htm;
			proxy_pass    http://xxxxxxxserver;
			client_max_body_size 20m;
        }

　　

重啟nginx,問題解決
