nginx转发规则

    server {
        listen       80;
        server_name  localhost;

        # 访问 http://localhost:80/ 时，转发到http://localhost:10001/
        location / {
			proxy_pass http://localhost:10001/;
        }
		
        # 访问 http://localhost:80/gateway/ 时，转发到http://localhost:10000/
		location /gateway/ {
			proxy_pass http://localhost:10000/;
        }

    }

注意：

以访问http://localhost:10000/gateway/为例：

一、如果最后多一个 /，会被转发到http://localhost:10000/

例：api是http://localhost/gateway/xxx，转发后为http://localhost/xxx 

		location /gateway/ {
			proxy_pass http://localhost:10000/;
        }

二、如果最后少一个 /，会被转发到http://localhost:10000/gateway/

  例：api是http://localhost/gateway/xxx，转发后为http://localhost/gateway/xxx 

		location /gateway/ {
			proxy_pass http://localhost:10000;
        }

   三、如果加上path，且最后多一个 /，会被转发到http://localhost:10000/gateway/ 

   例：api是http://localhost/gateway/xxx，转发后为http://localhost/gateway/xxx

		location /gateway/ {
			proxy_pass http://localhost:10000/gateway/;
        }

   四、如果加上path，且最后少一个 /，会被转发到http://localhost:10000/gateway

   例：api是http://localhost/gateway/xxx，转发后为http://localhost/gatewayxxx

		location /gateway/ {
			proxy_pass http://localhost:10000/gateway;
        }
