Python如何构建*real*ip地址的多客户端服务器

假设我在python中有一个多客户端服务器套接字和一个客户端套接字

服务器：（您不必阅读服务器的所有代码，只需知道它是一个多客户端服务器

import socket, select

CONNECTION_LIST = []    # list of socket clients
RECV_BUFFER = 4096 # Advisable to keep it as an exponent of 2
PORT = 5000

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# this has no effect, why ?
RealServerIP = ? # I want to have a real server ip which would let me connect to the server from any computer around the globe...
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((RealServerIP, PORT))
server_socket.listen(10)

# Add server socket to the list of readable connections
CONNECTION_LIST.append(server_socket)

print "Chat server started on port " + str(PORT)

while 1:
    # Get the list sockets which are ready to be read through select
    read_sockets,write_sockets,error_sockets = select.select(CONNECTION_LIST,[],[])

    for sock in read_sockets:

        #New connection
        if sock == server_socket:
            # Handle the case in which there is a new connection recieved through server_socket
            sockfd, addr = server_socket.accept()
            CONNECTION_LIST.append(sockfd)
            print "Client (%s, %s) connected" % addr

        #Some incoming message from a client
        else:
            # Data recieved from client, process it
            try:
                #In Windows, sometimes when a TCP program closes abruptly,
                # a "Connection reset by peer" exception will be thrown
                data = sock.recv(RECV_BUFFER)
                # echo back the client message
                if data:
                    sock.send(data)

            # client disconnected, so remove from socket list
            except:
                broadcast_data(sock, "Client (%s, %s) is offline" % addr)
                print "Client (%s, %s) is offline" % addr
                sock.close()
                CONNECTION_LIST.remove(sock)
                continue

server_socket.close()

（示例来自）

和3个客户，这是你能想象到的最简单的客户：

import socket # imports module named 'socket'
RealServerIP = ? # I need your help here.... read the continuation
my_socket = socket.socket() # creates new socket named 'my_socket'
my_socket.connect((RealServerIP, 5000)) # connects to the server
my_socket.send(str) # sends string to the server
data = my_socket.recv(1024) 
print data # prints data
my_socket.close() 

我想检查我的服务器是否可以同时与这3个客户端通信，所以我想让我的服务器成为一个公共服务器，就像Facebook的web服务器一样，等等。 所以世界上任何一台计算机都可以连接到它

因此，我试图找出如何使用与本地主机无关的特定IP和端口在线存储python服务器套接字，我希望它是真实的！就像您知道的任何聊天/web服务器一样。

如果您指的是用户连接到internet的IP，我不认为有办法通过

套接字

模块获取它，但是如果这有帮助的话，我可以使用

请求

模块做同样的事情

import requests

def get_ip():
    url = 'https://www.cmyip.com'
    user_ip = requests.get(url).content.decode("utf-8").split("My IP Address is ")[1].split(" <a class=")[0]
    return user_ip

导入请求
def get_ip（）：
url='1〕https://www.cmyip.com'
user_ip=requests.get（url）.content.decode（“utf-8”）.split（“我的ip地址是”）[1].split（“你需要绑定到你的ip地址而不是环回接口。或者在路由器/防火墙转发到服务器绑定到的任何地址/端口。谢谢。你能举个例子吗？”？
