Hi, all:

Recently, I have been do something about python webservice. Above all the methods of python webservice, soaplib is welcome and popular. When using soaplib, some problems puzzled me as follows.

porlbem 1: soaplib provide client-side or not？

Usually, I use soaplib as follows:

# file-name: soaplib_server.py:

# -*- coding:utf-8 -*-

from soaplib.wsgi_soap import SimpleWSGISoapApp

from soaplib.service import soapmethod

from soaplib.serializers.clazz import ClassSerializer

from soaplib.serializers.primitive import String, Integer, Array, DateTime

class SMS(ClassSerializer):

    class types:

        mobile = String

        content = String

class SMSService(SimpleWSGISoapApp):

    @soapmethod(String, _returns=Array(SMS))

    def get_sms(self,id):

        sms_lst = []

        sms = SMS()

        sms.mobile = "13011292217"

        sms.content = "hi, it's a test!"

        sms_lst.append(sms)

        return sms_lst

def make_client():

    from soaplib.client import make_service_client

    client = make_service_client('http://localhost:7789/' ,SMSService())

    return client

if __name__=='__main__':

    try:

        from wsgiref.simple_server import make_server

        server = make_server('localhost', 7789,SMSService())

        server.serve_forever()

    except ImportError:

        print "Error: example server code requires Python >= 2.5"

#file-name: suds_client.py

import suds

def test_soaplib3():

import logging

    logging.basicConfig(level=logging.ERROR)

    url = "http://localhost:7789/?wsdl"

    client = suds.client.Client(url,cache=None)

    print 'client', client

    output = client.service.get_sms('jia')

    print 'output', output

#NOTE: Certainly, it's okay. Below is the output: 

#output: 

client

Suds ( https://fedorahosted.org/suds/ )  version: 0.3.7 GA  build: R580-20091016

Service ( SMSService ) tns="SMSService.SMSService"

   Prefixes (1)

      ns0 = "SMSService.SMSService"

   Ports (1):

      (SMSService)

         Methods (1):

            get_sms(xs:string id, )

         Types (4):

            SMS

            SMSArray

            get_sms

            get_smsResponse

output (SMSArray){

   _type = "tns:SMSArray"

   SMS[] =

      (SMS){

         content = "hi, it's a test!"

         mobile = "13011292217"

      },

 }

#NOTE: do you find the "def make_client():" in the server-side ? It's no use when we use suds_client.py.  Now, let me talk the problem: 

I think soaplib is only a server-side and without client, you also can find the words as follows in "http://soaplib.github.com/soaplib/2_0/":

"Soaplib is an easy to use Python library for publishing SOAP web services using WSDL 1.1 standard, and answering SOAP 1.1 requests. With a very small amount of code, soaplib allows you to write a useful web service and deploy it as a WSGI application. (Non-WSGI scenarios are also supported.)" 

Most of scenes,  soaplib make as server and suds did for client. They can work together well.

In a web page, I found someone use client by soaplib, the client can be write as follows:

# file-name: soaplib_client.py

# -*- coding:utf-8 -*-

from soaplib_server3 import SMSService

from soaplib_server3 import make_client

import lxml.etree as et

a = make_client()

ret = a.get_sms('jia')

print 'ret:', ret

print 'type of ret:', type(ret)

for i,r in enumerate(ret):

    print 'i:',i, r.mobile, r.content

#output:

ret: [<soaplib_server3.SMS object at 0x8ecf7ec>]

type of ret: <type 'list'>

i: 0 13011292217 hi, it's a test!

#NOTE: now, the questions are :

1: Whether soaplib can provide client? 

2: If the answer for question 1 is okay, then the second question is : how to provide a webservice client using soaplib? Is the method "client = make_service_client('http://localhost:7789/' ,SMSService())" which is be used in my soaplib_serve.py?

3: if you agree that soaplib can make as websevice client-side, I would like to ask:　The client relays so heavily on sever-side, in the client-side, it requests some classes or modules in server side are imported. If we use soaplib-client to invoke a remote server(it may be developed in Java, C#, php or other language, or python which is not in the some local), how we get the class in server?

I do not whether i speak my question clearly. In actual fact, what I eager to know is how to provide a client-side using soaplib if soaplib can.  

part 2:  Is there someone find it spend much time and not stable to invoke soaplib using suds as follows.

#NOTE: the code can also be found in "http://soaplib.github.com/soaplib/2_0/pages/helloworld.html"

# soaplib_server.py

import soaplib

from soaplib.core.service import soap

from soaplib.core.service import rpc, DefinitionBase

from soaplib.core.model.primitive import String, Integer

from soaplib.core.server import wsgi

from soaplib.core.model.clazz import Array

from soaplib.core import Application

class HelloWorldService(DefinitionBase):

    @soap(String,Integer,_returns=Array(String))

    def say_hello(self,name,times):

        results = []

        for i in range(0,times):

            results.append('Hello, %s'%name)

        return results

if __name__=='__main__':

    print 'server begin running...'

    try:

        from wsgiref.simple_server import make_server

        soap_application = Application([HelloWorldService], 'tns')

        wsgi_application = wsgi.Application(soap_application)

        server = make_server('localhost', 7789, wsgi_application)

        server.serve_forever()

    except ImportError:

        print "Error: example server code requires Python >= 2.5"

# suds.py

import suds

def test_soaplib():

    

    url = "http://localhost:7789/?wsdl"

    client = suds.client.Client(url,cache=None)

    print 'client', client

    output = client.service.say_hello('jia',3)

    print 'output', output

when you invoke sus.py , it takes much time and a long time later returns the right result

”output (stringArray){

   string[] =

      "Hello, jia",

      "Hello, jia",

      "Hello, jia",

 }

“

or the exception below(it‘s not present exceptions as follows. most of time it return the result successfully after 2 or 3 minutes).

# okay, the problem is why sometimes the client return the exception and most of time return the correct results some minutes later?

Thanks for your time and concentration. Any relay is welcome.
