我有一个简单的Twisted客户端,它连接到一个Twisted服务器并查询索引。如果您查看class SpellClient
中的connectionMade()
函数,会发现query
是硬编码的。这是为了测试目的而这样做的。如何从外部传递查询给这个类?
代码 -
from twisted.internet import reactor
from twisted.internet import protocol
# a client protocol
class SpellClient(protocol.Protocol):
"""Once connected, send a message, then print the result."""
def connectionMade(self):
query = 'abased'
self.transport.write(query)
def dataReceived(self, data):
"As soon as any data is received, write it back."
print "Server said:", data
self.transport.loseConnection()
def connectionLost(self, reason):
print "connection lost"
class SpellFactory(protocol.ClientFactory):
protocol = SpellClient
def clientConnectionFailed(self, connector, reason):
print "Connection failed - goodbye!"
reactor.stop()
def clientConnectionLost(self, connector, reason):
print "Connection lost - goodbye!"
reactor.stop()
# this connects the protocol to a server runing on port 8000
def main():
f = SpellFactory()
reactor.connectTCP("localhost", 8090, f)
reactor.run()
# this only runs if the module was *not* imported
if __name__ == '__main__':
main()
