python socket簡單的c s示例

客戶端和服務端其實是對等的。只不過服務端是bind乙個位址，客服端是connect乙個位址。另外服務端需要呼叫listen()函式使得服務端可以接受連線請求。send，sendall,recv等等是兩邊都可以用的。下面是示例。

server.py

import socket

s = socket.socket(socket.af_inet, socket.sock_stream)
s.bind(
(socket.gethostname(),
1234))
s.listen(5)
while
true
:    socketclient, address = s.accept(
)print
(f"connection of  is established!"
)    data = socketclient.recv(
1024
)    data = data.decode(
"utf-8"
)    socketclient.send(
bytes
(f"hi , welcome to server!"
,"utf-8"))
socketclient.close

import socket

s = socket.socket(socket.af_inet, socket.sock_stream)
s.connect(
(socket.gethostname(),
1234))
s.sendall(
bytes
("raines"
,"utf-8"))
full_msg =
""while
true
:    st = s.recv(8)
iflen
(st)
<=0:
break
st = st.decode(
"utf-8"
)    full_msg += st
print
(full_msg)
