我有一个简单的Twisted客户端,它连接到Twisted服务器并查询索引。 如果你看到fn
connectionMade()
类SpellClient
中,查询
是硬编码的。这样做是为了测试目的。如何将这个查询从外部传递给这个类

该守则—

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()

协议,如SpellClient,可以作为self.factory访问其工厂。
…所以有很多方法可以做到这一点,但其中一种方法是在SpellFactory上创建另一个方法,例如setQuery,然后从客户端访问它

#...in SpellFactory:  
def setQuery(self, query):
    self.query = query


#...and in SpellClient:
def connectionMade(self):
    self.transport.write(self.factory.query)
…因此,大体上:

f = SpellFactory()
f.setQuery('some query')
...
…或者您可以为SpellFactory创建一个_init_方法,并将其传递到那里
