我试图实现一个超时,在没有连接收到定义的时间间隔时终止python脚本。到目前为止,我管理使用下面的代码来实现超时:套接字等待连接超时
import sys
import socket
# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Bind the socket to the port
server_address = ('192.168.43.112', 5001)
print >>sys.stderr, 'starting up on %s port %s' % server_address
sock.bind(server_address)
# Listen for incoming connections
sock.listen(1)
while True:
try:
# Wait for a connection
print >>sys.stderr, 'waiting for a connection'
connection, client_address = sock.accept()
try:
print >>sys.stderr, 'connection from', client_address
# Receive the data in small chunks and retransmit it
while True:
data = connection.recv(16)
print >>sys.stderr, 'received "%s"' % data
if data:
print >>sys.stderr, 'Do stuff here'
else:
print >>sys.stderr, 'no more data from', client_address
sock.settimeout(5)
break
finally:
# Clean up the connection
connection.close()
except socket.timeout:
break
的代码在这个意义上正常工作,建立一个连接,并结束了非常相同的连接,5秒后脚本终止后。但是,如果超时窗口中我尽量让另一个方面,我有以下错误:
starting up on 192.168.43.112 port 5001
waiting for a connection
connection from ('192.168.43.1', 47550)
received "Data 0
"
Do stuff here
received ""
no more data from ('192.168.43.1', 47550)
waiting for a connection
connection from ('192.168.43.1', 39010)

25 while True:
---> 26 data = connection.recv(16)
27 print >>sys.stderr, 'received "%s"' % data

这实际上是诀窍。我在OS X上运行这个。感谢你的解释。 – dudas
