我在服务器中成功！

我的服务器python脚本如下:

My server python script is below:

    import socket
    host='0.0.0.0'
    port=2345
    s=socket.socket()
    s.bind((host,port))
    s.listen(2)
    while True:
    conn,addr=s.accept()
    print("Connected by",addr)
    data=conn.recv(1024)
    print("received data:",data)
    conn.send(data)
    conn.close()

我的客户端python脚本如下:

My Client python script is below:

import socket
s=socket.socket()
host="xx.xx.xx.xx"       #This is your Server IP!
port=2345
s.connect((host,port))
s.send(b"hello")
rece=s.recv(1024)
print("Received",rece)
s.close()

脚本中有两点需要注意:

There is two points needed to be careful in the script:

1.服务器的主机必须为

1.The host of the Server must is

'0.0.0.0'

'0.0.0.0'

以便python脚本可以使用服务器中的所有接口

So that the python script could user all interfaces in the server

2.我已经通过提示符找到问题的错误:

2.I have find the question's error through the prompt:

TypeError:需要一个类似字节的对象，而不是'str'

TypeError: a bytes-like object is required, not 'str'

这意味着'send'方法中的每个字符串消息都需要转换为'bytes-like object'，所以正确的是

It means every string message in the 'send' method need to convert to 'bytes-like object',So the correct is

s.send(b"hello")

s.send(b"hello")

重要的是，这是 b'hello'，而不是'hello'

It is important that this is b'hello' not is 'hello'
