解析X-Forwarded - 在Heroku上用werkzeug获得IP [英] Parse X-Forwarded-For to get ip with werkzeug on Heroku

问题描述

Heroku代理从客户端到服务器的请求，所以你必须解析X-Forwarded-For找到原始IP地址。

一般的格式X-Forwarded-For是：

  X-Forwarded-For：client1，proxy1，proxy2 
  

在烧瓶上使用werkzeug，我试图想出一个解决方案来访问客户端的原始IP地址。

有没有人知道这样做的好方法？

谢谢！

werkzeug.datastructures.Headers 。你应该可以这样做：

  provided_ips = request.headers.getlist（X-Forwarded-For） 
＃列表中的第一个条目应该是客户的IP。 
  

或者，您可以使用 request.access_route （感谢@Bastian指出！）：

  provided_ips = request.access_route 
＃列表中的第一项是客户的IP 
  pre> 
Heroku proxies requests from a client to server, so you have to parse the X-Forwarded-For to find the originating IP address.

The general format of the X-Forwarded-For is:
X-Forwarded-For: client1, proxy1, proxy2
Using werkzeug on flask, I'm trying to come up with a solution in order to access the originating IP of the client.

Does anyone know a good way to do this?

Thank you!
解决方案
Werkzeug (and Flask) store headers in an instance of werkzeug.datastructures.Headers.  You should be able to do something like this:
provided_ips = request.headers.getlist("X-Forwarded-For")
# The first entry in the list should be the client's IP.
Alternately, you could use request.access_route (thanks @Bastian for pointing that out!):
provided_ips = request.access_route
# First entry in the list is the client's IP
