tcp-ip - Python使用socket发送完tcp的包后如何接收返回的数据？

Question

#encoding=utf-8

import socket,time

tcpT4Client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "Done........"
tcpT4Client.connect(('192.168.0.150', 8000))
print "TCP IPv4 TCP mode connecting..."
while True:
    time.sleep(1)
    tcpT4Client.send('7E1501046601020000837E')

不知道怎么接受数据。。求指教

Answer 1

https://wiki.python.org/moin/TcpCommunication

官方的例子改了一下:

#!/usr/bin/env python

import socket


TCP_IP = '192.168.0.150'
TCP_PORT = 8000
BUFFER_SIZE = 20  # Normally 1024, but we want fast response

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((TCP_IP, TCP_PORT))
s.listen(1)

conn, addr = s.accept()
print 'Connection address:', addr
while 1:
    data = conn.recv(BUFFER_SIZE)
    if not data: break
    print "received data:", data
    conn.send(data)  # echo
conn.close()

Answer 2

楼上给的是对端（server）接收，题主没说清是本端还是对端的接收
这里说下本端（client）接收

# 在send之后接收服务器的回应
data = tcpT4Client.recv(1024)
print data

1024是接收的最大长度，可自己设置
