flask+nginx如何获得真实IP

如果是通过 flask 的 request.remote_addr获取的 ip 都是 127.0.0.1

解决方案:

nginx.conf中添加

1
2
3

# proxy_set_header Host $host:80; 
# proxy_set_header X-Real-IP $remote_addr; 
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

全文

server {
    listen 8888;
    server_name 0.0.0.0;
    charset utf-8;
    client_max_body_size 75M;
    location /static{
    alias /home/apollo3d/Documents/Cl/webenv/.../static;  
}

location / {
    include uwsgi_params;
    uwsgi_pass 127.0.0.1:8889;	
    uwsgi_param UWSGI_SCRIPT app:app;   # 启动flask的文件:Flask的实例
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
	}
}

Python代码

if request.headers.getlist("X-Forwarded-For"):
    ip = request.headers.getlist("X-Forwarded-For")[0]
else:
    ip = request.remote_addr

拓展:

X-Forwarded-For 可能会有多个 IP ，如果浏览器使用了代理的话
正确的做法应该是抓 X-Real-IP，或者分隔 X-Forwarded-For取第 1 个值
