Python扭曲客户端
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fnPython扭曲客户端,python,twisted,twisted.internet,twisted.client,Python,Twisted,Twisted.internet,Twisted.client,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fnconnectionMade()在类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)
connectionMade()
在类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
