在本文中，我们将看到如何使用带Python的套接字编程来创建服务器和客户端聊天室系统。
套接字是任何通信通道的端点。这些用于连接服务器和客户端。套接字是双向的。在该区域中，我们将为每个端设置套接字，并通过服务器在不同客户端之间设置聊天室系统。服务器端有一些端口可与客户端套接字连接。当客户端尝试使用相同的端口连接时，将为聊天室建立连接。
基本上有两个部分。服务器端和客户端。服务器端脚本运行时，它将等待任何活动的连接请求。建立一个连接后，即可与其通信。
在这种情况下，我们使用本地主机。如果机器通过局域网连接，那么我们可以使用IP地址进行通信。服务器将显示其IP，并要求该服务器的名称。在客户端，我们必须提到一个名称，以及要连接的服务器的IP地址。
服务器端代码import time, socket, sys
print('Setup Server...')
time.sleep(1)
#Get the hostname, IP Address from socket and set Port
soc = socket.socket()
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())
whileTrue:
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)
客户端代码import time, socket, sys
print('Client Server...')
time.sleep(1)
#Get the hostname, IP Address from socket and set Port
soc = socket.socket()
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.')
whileTrue:
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())
