python網(wǎng)絡編程--socket

1.服務端
1.1聲明socket對象
server=socket.socket(AF.INET,socket.SOCK_STREAM)
1.2綁定ip、端口
server.bind(localhost,6969)
1.3開始監(jiān)聽
server.listen()
1.4接收監(jiān)聽連接及地址
conn,addr=server.accept()

1.5接收數(shù)據(jù)
data=conn.recv(1024)
print(data)
1.6發(fā)送數(shù)據(jù)
conn.send(data)
1.7.關閉連接
conn.close()

import socket
#1.實例化socket
server=socket.socket()
#2.綁定端口號
server.bind(('localhost',6969))
#3.開啟監(jiān)聽
server.listen()
print('等待連接')
#4.等待連接
conn,addr=server.accept()
while True:
    #5.接收數(shù)據(jù)
    data=conn.recv(1024)
    if data=='':
        break
    print(data.decode())
    #6.發(fā)送數(shù)據(jù)
    conn.send('數(shù)據(jù)接收成功'.encode())
#7.關閉連接
conn.close()

2.客戶端
2.1聲明socket對象
client=socket.socket(AF.INET,socket.SOCK_STREAM)
2.2連接服務端
client.connect(('localhost',6969))
2.3發(fā)送數(shù)據(jù)
client.send(data)
2.4接收數(shù)據(jù)
client.recv()
2.5關閉連接
client.close()

import socket
#1.實例化socket
client=socket.socket()
#2.連接服務端
client.connect(('localhost',6969))
while True:
    data=input('>>:')
    #3.發(fā)送數(shù)據(jù)
    client.send(data.encode())
    #4.接收數(shù)據(jù)
    data_server=client.recv(1024)
    print(data_server.decode())
client.close()
