[Twisted-Python] How to call remote server method to read a file on the server machine useing perspective broker ?

[yangyouxiu]

Hi, all!
I'm trying to read a file on the server with pb, and got an error. Following is my code, what's the problem?

***********************pb1server.py
#!/usr/bin/env python

# Copyright (c) Twisted Matrix Laboratories.
# See LICENSE for details.

from twisted.spread import pb

class Two(pb.Referenceable):
    def remote_three(self, arg):
        print "Two.three was given", arg
        f=open('/home/gddw/Desktop/test','wr')
        content = f.readline()
        print content
class One(pb.Root):
    def remote_getTwo(self):
        two = Two()
        print "returning a Two called", two
        return two

from twisted.internet import reactor
reactor.listenTCP(8800, pb.PBServerFactory(One()))
reactor.run()
*************************pb1client.py
#!/usr/bin/env python

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

def main():
    factory = pb.PBClientFactory()
    reactor.connectTCP("localhost", 8800, factory)
    def1 = factory.getRootObject()
    def1.addCallbacks(got_obj1, err_obj1)
    reactor.run()

def err_obj1(reason):
    print "error getting first object", reason
    reactor.stop()

def got_obj1(obj1):
    print "got first object:", obj1
    print "asking it to getTwo"
    def2 = obj1.callRemote("getTwo")
    def2.addCallbacks(got_obj2)

def got_obj2(obj2):
    print "got second object:", obj2
    print "telling it to do three(12)"
    obj2.callRemote("three", 12)
main()
