nginx uwsgi_pass 与proxy_pass 获取真实IP地址的方式

proxy_pass 方式

proxy_set_header X-Real-IP  $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

uwsgi_pass 方式

uwsgi_param   HTTP_X-Real-IP        $remote_addr;
uwsgi_param   HTTP_X-Forwarded-For  $proxy_add_x_forwarded_for;

使用python3 flask框架时，获取的方式为：

current_ip = request.remote_addr
if request.headers.get("X-Real-Ip") is not None:
	current_ip = request.headers.get("X-Real-Ip")
