How do I get the external IP of a socket in Python?
提问by verix
When I call socket.getsockname()on a socket object, it returns a tuple of my machine's internal IP and the port. However, I would like to retrieve my external IP. What's the cheapest, most efficient manner of doing this?
当我调用socket.getsockname()套接字对象时，它返回我机器的内部 IP 和端口的元组。但是，我想检索我的外部 IP。这样做最便宜、最有效的方式是什么？

This isn't possible without cooperation from an external server, because there could be any number of NATs between you and the other computer. If it's a custom protocol, you could ask the other system to report what address it's connected to.
如果没有外部服务器的合作，这是不可能的，因为您和另一台计算机之间可能存在任意数量的 NAT。如果是自定义协议，您可以要求其他系统报告它连接到的地址。

The only way I can think of that's guaranteed to give it to you is to hit a service like http://whatismyip.com/to get it.
我能想到的唯一方法就是使用http://whatismyip.com/ 之类的服务来获取它。

You need to make connection to an external Server And Get Your Public IP From The Response
您需要连接到外部服务器并从响应中获取您的公共 IP
like this:
像这样：
import requests
myPublic_IP = requests.get("http://wtfismyip.com/text").text.strip()
print("\n[+] My Public IP: "+ myPublic_IP+"\n")
