请教：使用socket.recv(1024)时出现阻塞，怎么处理啊？

dongdong82CU

写了一个简单的socket的client程序，连接服务器，在使用socket.recv（1024）接收服务器返回的消息时，
出现了阻塞，程序就一直停在那不往下走了，怎么办啊？？


import socket
host = '192.168.1.101'
port = 4567
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect(host,port)
s.send("1111111111")

buf= s.recv(1024)

只有结束程序了，要不就等到有返回

开个线程

设个超时时间用settimeout,或者线程, select什么的都可以


   

CMAX

socket.setblocking(flag)
Set blocking or non-blocking mode of the socket: if flag is 0, the socket is set to non-blocking, else to blocking mode. Initially all sockets are in blocking mode. In non-blocking mode, if a recv() call doesn’t find any data, or if a send() call can’t immediately dispose of the data, a error exception is raised; in blocking mode, the calls block until they can proceed. s.setblocking(0) is equivalent to s.settimeout(0.0); s.setblocking(1) is equivalent to s.settimeout(None).

这个是你需要的么
