Python PB中的Twisted，服务端客户端函数调用

Question

你能帮忙吗....我真的很挣扎。我无法通过以下方式从客户端调用服务器中的两个函数 program.Help 我了解如何提前从 client.Thanks 调用服务器中的多个函数

Server.py

#!/usr/bin/env python
from twisted.spread import pb
from twisted.internet import reactor

class Main(pb.Root):
    def remote_name(self,idno):
            print'Id NO:', idno
            def num(idno):
                    switcher={
                            1:'\t\tFirst',
                            2:'\t\tSecond',
                            3:'\t\tThird',
                            } 
                    return switcher.get(idno, 'Invalid Number')
            print num(idno)
    def remote_hello(self, st):
            print'From Client:', st
            return st    
if __name__=='__main__':
      reactor.listenTCP(5000,pb.PBServerFactory(Main()))
      reactor.run()

Client.py

#!/usr/bin/env python

from twisted.spread import pb
from twisted.internet import reactor

 def main():
      f = pb.PBClientFactory()
      reactor.connectTCP('localhost',5000,f)
      d=f.getRootObject()
      print 'Enter ID No:'
      no=input()
      d.addCallback(lambda new:new.callRemote('name',no))
      d.addCallback(lambda obj:obj.callRemote('hello', 'hello world'))
      reactor.run()

if __name__=='__main__':
      main()

如果我尝试执行此操作，remote_name 函数只有 executed.There 没有来自 remote_hello 的响应 function.This 是我的问题。

Answer 1

  d = f.getRootObject()
  def gotObject(new):
      no = input()
      d2 = new.callRemote('name',no)
      d2.addCallback(lambda ignored: new.callRemote('hello', 'hello world'))
      return d2
  d.addCallback(gotObject)
  reactor.run()

或者

from twisted.internet.defer import inlineCallbacks

@inlineCallbacks
def doIt():
    f = pb.PBClientFactory()
    reactor.connectTCP('localhost',5000,f)
    new = yield f.getRootObject()
    print 'Enter ID No:'
    no = input()
    yield new.callRemote('name',no)
    yield new.callRemote('hello', 'hello world')

def main():
    d = doIt()
    reactor.run()
