【bug】上传图片出现错误(413 Request Entity Too Large)

解决

nginx上传文件大小受到限制，需要调整nginx配置。nginx修改上传文件大小限制client_max_body_size 1000M;

nginx修改上传文件大小限制，举例如下：
server {
        listen       80;
        server_name  localhost;
	client_max_body_size 1000M;

	location /web {
            alias   D:/web;
            index main.html;			
        }
	location /web/service {
            proxy_pass   http://HOST/service;		
        }
	location /web/service/upload {
            proxy_pass   http://HOST/upload;
        }		
    }
