1. 正向代理
location /test {
proxy_pass http://localhost:8080/test;
}
Nginx会把请求转发到Proxy，Proxy直接返回数据到请求方
2. 反向代理
location /test {
proxy_pass http://localhost:8080/test;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
Nginx会向Proxy请求数据，然后再把数据返回到请求方
