Django获取request中的真实IP

1、如果没有通过nginx的反向代理：request.META.get("REMOTE_ADDR")

2、在nginx配置中增加HTTP_X_FORWARDED_FOR 

　X-Forwarded-For请求头格式：X-Forwarded-For:client, proxy1, proxy2

proxy_set_header Host $host;
      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_f

　　x = request.META.get("HTTP_X_FORWARD_FOR")
　　ip = x.split(',')[0] if x else '-'
