示例1: IPRoute
# 需要导入模块: from pyroute2 import IPRoute [as 别名]
# 或者: from pyroute2.IPRoute import sendto [as 别名]
from socket import SOL_SOCKET
from socket import SO_REUSEADDR
ip = IPRoute()
##
#
pr = socket(AF_INET, SOCK_STREAM)
pr.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
pr.bind(('127.0.0.1', 4011))
pr.listen(1)
(client, addr) = pr.accept()
ip._s_channel = client
##
#
poll = select.poll()
poll.register(client, select.POLLIN | select.POLLPRI)
poll.register(ip, select.POLLIN | select.POLLPRI)
while True:
events = poll.poll()
for (fd, event) in events:
if fd == client.fileno():
try:
ip.sendto(client.recv(16384), (0, 0))
except:
sys.exit(0)
else:
client.send(ip.recv(16384))
示例2: Server
# 需要导入模块: from pyroute2 import IPRoute [as 别名]
# 或者: from pyroute2.IPRoute import sendto [as 别名]

'name': str,
'cookie': cookie,
'argv': [...],
'kwarg': {...}}
# response
{'stage': 'command',
'error': exception or None,
'return': retval,
'cookie': cookie}
Right now the protocol is synchronous, so there is not
need in cookie yet. But in some future it can turn into
async, and then cookies will be used to match messages.
The final stage is 'shutdown'. It terminates the worker
thread, has no response and no messages can passed after.
