这篇文章主要介绍了Python TCP通信客户端服务端代码实例,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
TCP客户端:
import argparse, socket,sys
import time
# socket.setdefaulttimeout(20)
def recvall(sock, length):
data = b''
while len(data) < length:
more = sock.recv(length - len(data))
if not more:
raise EOFError('总共有%dbytes,但只收到了%dbytes' % (length, len(data)))
data += more
return data
if __name__ == '__main__':
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('192.168.137.1', 10000))
print('客户的分配了socket:', sock.getsockname())
i=0
for x in range(4):
# try:
text = '我是客户端你是服务器嚯嚯嚯!'.encode('utf-8')
i=i+len(text)
sock.sendall(text)
sys.stdout.flush()
print("已发送:",i)
# except ConnectionResetError:
# pass
sock.shutdown(socket.SHUT_WR)
num = 0
while True:
reply = sock.recv(48) # b'Farewell, client'的长度
num += len(reply)
print('接收:',num)
if not reply:
print("ok")
break
# print('服务器返回:', reply.decode('utf-8'))
print("理论上应该关闭sock")
sock.close()
time.sleep(1)
TCP服务端:
import argparse, socket,sys
def recvall(sock, length):
data = b''
while len(data) < length:
more = sock.recv(length - len(data))
if not more:
raise EOFError('总共有%dbytes,但只收到了%dbytes' % (length, len(data)))
data += more
return data
if __name__ == '__main__':
sc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sc.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
sc.bind(('', 10000))
sc.listen()
print('正在侦听{}...'.format(sc.getsockname()))
num = 0
while True:
scc, address = sc.accept()
print('连接来自:', address)
print('socket名字:', scc.getsockname())
print('socket peer:', scc.getpeername())
while True:
message = scc.recv(42)#recvall(scc, 24) # 尝试 12,,20,28会是什么结果
if not message:
break
# print('收到16-octet消息:', repr(message))
print('收到16-octet消息:', (message.decode('utf-8')))
scc.sendall(message)
sys.stdout.flush()
num += len(message)
print("已发送:",num)
scc.close()
print('应答发送,socket关闭')
sc.close()
