在本文中，我們将看到如何使用帶Python的套接字程式設計來建立伺服器和用戶端聊天室系統。
套接字是任何通信通道的端點。這些用于連接配接伺服器和用戶端。套接字是雙向的。在該區域中，我們将為每個端設定套接字，并通過伺服器在不同用戶端之間設定聊天室系統。伺服器端有一些端口可與用戶端套接字連接配接。當用戶端嘗試使用相同的端口連接配接時，将為聊天室建立連接配接。
基本上有兩個部分。伺服器端和用戶端。伺服器端腳本運作時，它将等待任何活動的連接配接請求。建立一個連接配接後，即可與其通信。
在這種情況下，我們使用本地主機。如果機器通過區域網路連接配接，那麼我們可以使用IP位址進行通信。伺服器将顯示其IP，并要求該伺服器的名稱。在用戶端，我們必須提到一個名稱，以及要連接配接的伺服器的IP位址。
伺服器端代碼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)
用戶端代碼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())
