开始轮询循环后,第一次迭代后打印的所有消息都要求我按下终端输入以显示它。
#!/usr/bin/python
import socket, select, os, pty, sys
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('', 5007))
s.listen(5)
mypoll = select.poll()
mypoll.register(s.fileno() )
while True:
print "poll time"
subr = mypoll.poll()
for x in subr[0]:
if x == s.fileno():
conn, addr = s.accept()
pid, fd = pty.fork()
if pid != 0:
mypoll.register(fd)
print "done. go back to poll now"
else:
print "forked"
#handles new connection
else:
data = os.read(x,1024)
print data
答案 0 :(得分:1)
第一次迭代后,你没有注册pty fd,然后轮询它吗?并且它的fd永远不会等于socket fd,所以你将os.read pty fd。现在不是从您的终端读取?因此不输入退货会导致它“打印数据”吗?
