Python3 Socket 例子

最近看书浏览到 Socket 网络模块，想尝试用 Python3 写一下 Socket 的例子，结果遇到一点坑，下面是调整后跑通的例子，方便以后查看。

两个类：

1. 服务端
2. 客户端

运行过程：

1. 首先启动服务端，监听请求；
2. 然后通过客户端去发出请求；
3. 接下来观察输出；

服务端源代码SocketServer.py：

import socket

s = socket.socket()

host = socket.gethostname()
port = 1234
s.bind((host, port))

s.listen(5)
while True:
    c, addr = s.accept()
    print('Got connection from {}'.format(addr))
    print('Received message == {}'.format(c.recv(1024).decode('utf-8')))
    c.send(b'this come from server')
    c.close()

客户端源代码SocketClient.py：

import socket

s = socket.socket()

host = socket.gethostname()
port = 1234

s.connect((host, port))
print('Try to send connection from {}'.format(host))
s.sendall(b"this come from client")
print(s.recv(1024).decode('utf-8'))

服务端输出如下：

Got connection from ('x.x.x.x', x)
Received message == this come from client

客户端输出如下：

Try to send connection from x.local
this come from server

Process finished with exit code 0
