python 客户端

import socketa="你好"
b=bytes(a,encoding='utf-8')
print(b)
c=str(b,encoding='utf-8')
print(c)b=a.encode('utf-8')
print(b)

print(c)cs=socket.socket()
# 连接服务端
h=cs.connect(("192.168.42.191",5000))

# 接受消息
data=cs.recv(1024)
print(type(data))
print(data)
print(data.decode('utf-8'))#发送消息
mess=input("请输入你想发的消息")

python 服务端

import socket
# 服务端应用ss = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ss.bind(("0.0.0.0", 5000))  # 服务器绑定ip
ss.listen(5)  # 开始监听
tcp1, add = ss.accept()  # 阻塞进程，等待客户端连接
print('tcp1', tcp1)
print('客户端连接成功，客户端IP地址', add)tcp1.sendall("我是python".encode('utf-8'))
data = tcp1.recv(102400)  # 接受消息
data = str(data, encoding='utf-8')
print('接受的消息是：',data)
