如果我的理解是正确的,那么文档中的这个例子只能写"你好"一旦:
from twisted.internet.protocol import DatagramProtocol
from twisted.internet import reactor
class Helloer(DatagramProtocol):
def startProtocol(self):
host = "192.168.1.1"
port = 1234
self.transport.connect(host, port)
print "now we can only send to host %s port %d" % (host, port)
self.transport.write("hello") # no need for address
def datagramReceived(self, data, (host, port)):
print "received %r from %s:%d" % (data, host, port)
# Possibly invoked if there is no server listening on the
# address to which we are sending.
def connectionRefused(self):
print "No one listening"
# 0 means any port, we don't care in this case
reactor.listenUDP(0, Helloer())
reactor.run()
我有一些问题:
写什么好方法"你好"什么时候收到数据报?在startProtocol()
中致电datagramReceived()
?
假设在收到数据报后要写入另一条消息,例如,#34;任何人回家?"是否应该实施课程AnyoneHome(DatagramProtocol)
?但应该如何"链接"到Helloer
并连接到反应堆?

解决。看起来我可以在self.transport.write()
中拨打datagramReceived()
。
