nginx反向代理之后flask无法获取真实访问ip

flask.request.remote_addr一直都是127.0.0.1

解决：https://www.jianshu.com/p/98bc849ef01a

proxy_set_header Host $host:8080;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

以上的nginx配置我已经配置了的，将获取对端地址的代码修改为flask.request.headers['X-Real-Ip']即可。

所以代码如下所示：
try:
    url_param['ip'] = flask.request.headers['X-Real-Ip']
except KeyError:
    url_param['ip'] = flask.request.remote_addr
