tcp循环发送消息

服务端：

# import socket
#
# tcp_server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# tcp_server.bind(('127.0.0.1', 8888))
# tcp_server.listen(128)
# coon, addr = tcp_server.accept()
from socket import *

tcp_server = socket(AF_INET, SOCK_STREAM)
tcp_server.bind(('127.0.0.1', 8080))
tcp_server.listen(125)
conn, addr = tcp_server.accept()
print('双向连接是', conn)
print('客户端地址', addr)
while True:
    data = conn.recv(1204)
    print('客户端发来的消息是', data.decode())
    conn.send(data.upper())
conn.close()
tcp_server.close()

客户端：

from socket import *

tcp_client = socket(AF_INET,SOCK_STREAM)
tcp_client.connect(('127.0.0.1',8080))
while True:
    msg = input('++++++>')
    tcp_client.send(msg.encode())
    print('客户端已经发送消息')
    data = tcp_client.recv(1204)
    print('收到服务端发来的消息',data.decode())
tcp_client.close()
