服务端:
import socket
print("程序开始")
# 创建套接字
mySocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 设置IP和端口
host = socket.gethostname()
port = 3333
# bind绑定该端口
mySocket.bind((host, port))
# 监听
mySocket.listen(10)
while True:
# 接收客户端连接
print("等待连接....")
client, address = mySocket.accept()
print("新连接")
print("IP is %s" % address[0])
print("port is %d\n" % address[1])
while True:
# 发送消息
msg = input("----------------------发送:")
client.send(msg.encode())
print("发送完成")
if msg == "EOF":
break
if msg == "quit":
client.close()
mySocket.close()
print("程序结束\n")
exit()
# 读取消息
msg = client.recv(1024)
print("----------------------读取:", msg)
print("读取完成")
if msg == b"EOF":
break
if msg == b"quit":
client.close()
mySocket.close()
print("程序结束\n")
exit()
客户端:
import socket
print("程序开始")
# 创建套接字
mySocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 设置ip和端口
host = socket.gethostname()
port = 3333
# 连接到服务器
mySocket.connect((host, port))
print("连接到服务器")
while True:
# 接收消息
print("----------------------读取:", end="")# 不换行输出
msg = mySocket.recv(1024)
print("%s" % msg)
print("读取完成")
if msg == b"EOF":
break
if msg == b"quit":
mySocket.close()
print("程序结束\n")
exit()
# 发送消息
msg = input("----------------------发送:")
mySocket.send(msg.encode())
print("发送完成")
if msg == "EOF":
break
if msg == "quit":
mySocket.close()
print("程序结束\n")
exit()
print("程序结束\n")
注意错误:TypeError: a bytes-like object is required, not 'str'
解决方法:
b'msg'或者如下
msg = input("----------------------发送:") client.send(msg.encode())
msg = client.recv(1024) print("----------------------读取:", msg)
