python - 两个不同的远程服务器使用python进行通信

Question

这是我在远程服务器上运行的服务器代码。

serv.py

import time, socket, sys
print('Setup Server...')
time.sleep(1)
#Get the hostname, IP Address from socket and set Port
soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host_name = socket.gethostname()
ip = socket.gethostbyname(host_name)
port = 1234
soc.bind((host_name, port))
print(host_name, '({})'.format(ip))
name = input('Enter name: ')
soc.listen(1) #Try to locate using socket
print('Waiting for incoming connections...')
connection, addr = soc.accept()
print("Received connection from ", addr[0], "(", addr[1], ")\n")
print('Connection Established. Connected From: {}, ({})'.format(addr[0], addr[0]))
#get a connection from client side
client_name = connection.recv(1024)
client_name = client_name.decode()
print(client_name + ' has connected.')
print('Press [bye] to leave the chat room')
connection.send(name.encode())
while True:
   message = input('Me > ')
   if message == 'bye':
      message = 'Good Night...'
      connection.send(message.encode())
      print("\n")
      break
   connection.send(message.encode())
   message = connection.recv(1024)
   message = message.decode()
   print(client_name, '>', message)

这是我在本地系统上运行的客户端代码。

clie.py

import time, socket, sys
print('Client Server...')
time.sleep(1)
#Get the hostname, IP Address from socket and set Port
soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
shost = socket.gethostname()
ip = socket.gethostbyname(shost)
#get information to connect with the server
print(shost, '({})'.format(ip))
server_host = input('Enter server\'s IP address:')
name = input('Enter Client\'s name: ')
port = 1234
print('Trying to connect to the server: {}, ({})'.format(server_host, port))
time.sleep(1)
soc.connect((server_host, port))
print("Connected...\n")
soc.send(name.encode())
server_name = soc.recv(1024)
server_name = server_name.decode()
print('{} has joined...'.format(server_name))
print('Enter [bye] to exit.')
while True:
   message = soc.recv(1024)
   message = message.decode()
   print(server_name, ">", message)
   message = input(str("Me > "))
   if message == "bye":
      message = "Leaving the Chat room"
      soc.send(message.encode())
      print("\n")
      break
   soc.send(message.encode())

现在，如果主机服务器不同，则无法建立连接。但如果主机相同，则它可以正常工作并正确发送文本。我想在不同的服务器上运行此代码该怎么做请帮助我。

Answer 1

在服务器脚本中，您使用:

host_name = socket.gethostname()

这可能会给你“127.0.0.1”。

您需要的是服务器监听“0.0.0.0”以接受来自任何地方的连接。

所以这可能会做:

host_name = "0.0.0.0"
