Soket编程：客户端-服务端单线程通信

客户端：

# 导入socket模块
import socket
# 创建socket对象
ClientSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 获取本机IP地址
host = socket.gethostbyname(socket.gethostname())
# 设置连接IP的端口
port = 12580
# 将IP地址和端口设置为元组,方便使用
my_data = (host, port)
# 链接服务器
ClientSocket.connect(my_data)
while True:
    User_Message = input("向服务端说:")
    ClientSocket.send(User_Message.encode("utf-8"))
    Message = ClientSocket.recv(2048)
    print("服务端说:" + str(Message.decode("utf-8")))
ClientSocket.close(

服务端：

# 导入socket模块
import socket
# 创建服务器socket对象
ServicesSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 设置服务端的IP地址
host = socket.gethostbyname(socket.gethostname())
# 设置服务端的端口
port = 12580
# 将IP地址和端口设置为元组,方便使用
my_data = (host, port)
# 绑定IP和端口
ServicesSocket.bind(my_data)
# 设置最大连接数
ServicesSocket.listen(5)
while True:
    # 等待客户
    ClientSocket, addr = ServicesSocket.accept()
    while True:
        # 接收客户端传输过来消息,最大为2048字节
        Message = ClientSocket.recv(2048)
        print("客户端说:" + str(Message.decode("utf-8")))
        Services_Message = input("向客户端说:")
        # 向客户端发送数据
        ClientSocket.send(Services_Message.encode("utf-8"))
ServicesSocket.close()

运行结果：首先启动服务端，在启动客户端发送信息
