配置nginx.conf文件

	server {
        listen       9800;
        server_name  localhost;
		
        #后台接口配置
        location ~ /quartz/ {
            proxy_pass http://192.168.X.XXX:9830;
			proxy_read_timeout 360s;
			proxy_send_timeout 360s;
			proxy_set_header Host $http_host; 
			proxy_set_header X-Real-IP $remote_addr; 
			proxy_set_header X-Forwarded-Proto $scheme;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			add_header Front-End-Https on;
			add_header 'Access-Control-Allow-Methods' 'GET,POST';
			add_header 'Access-Control-Allow-Origin' $http_origin;
			add_header 'Access-Control-Allow-Credentials' 'true';
			add_header 'Access-Control-Allow-Headers' 'Accept,Authorization,Cache-Control,Content-Type,DNT,If-Modified-Since,Keep-Alive,Origin,User-Agent,X-Mx-ReqToken,X-Requested-With';
			}
        }
		
		location / {
            root   html;
            index  index.html index.htm;
        }
		
		location @router {
            rewrite ^.*$ /index.html last;
        }
		
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

一、如何配置你的nginx.conf
添加一个server{}，这是你的服务，listen参数是你要监听的端口，这个端口可以自定义，server_name localhost，这个一般就是A服务器的域名地址，记住这个地址+端口+/参数/(127.0.0.1:9800/quartz/) 是映射location，也就是请求的地址会被代理成 proxy_pass http://192.168.X.XXX:9830这个地址，A服务器就可以跨服务器请求B服务器的资源；

二、添加Access-Control-Allow-Methods请求头

add_header Front-End-Https on;
add_header 'Access-Control-Allow-Methods' 'GET,POST';
add_header 'Access-Control-Allow-Origin' $http_origin;
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Accept,Authorization,Cache-Control,Content-Type,DNT,If-Modified-Since,Keep-Alive,Origin,User-Agent,X-Mx-ReqToken,X-Requested-With';
