使用soaplib (服务器端)和suds (客户端)的Python soap

Question

此问题与：Python SOAP server / client相关

在使用soap和python的情况下，建议使用soaplib (http://wiki.github.com/jkp/soaplib)作为soap服务器，使用suds (https://fedorahosted.org/suds/)作为soap客户端。我的目标是用python创建可供多个客户端(java等)使用的soap服务。我尝试了来自soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld)的HelloWorld示例。当客户端也在使用soaplib时，它工作得很好。

然后，我尝试使用suds作为使用HelloWorld服务的客户端，但失败了。-Why这是怎么回事？soaplib服务器在不同的客户端使用时会出现问题吗？

下面是服务器的代码：

from soaplib.wsgi_soap import SimpleWSGISoapApp
from soaplib.service import soapmethod
from soaplib.serializers.primitive import String, Integer, Arraycode
class HelloWorldService(SimpleWSGISoapApp):
@soapmethod(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__':
from cherrypy.wsgiserver import CherryPyWSGIServer
#from cherrypy._cpwsgiserver import CherryPyWSGIServer
# this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0
server = CherryPyWSGIServer(('localhost',7789),HelloWorldService())
server.start()

这是soaplib客户端：

from soaplib.client import make_service_client
from SoapServerTest_1 import HelloWorldService
client = make_service_client('http://localhost:7789/',HelloWorldService())
print client.say_hello("Dave",5)

结果：

>>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave']

这是suds客户端：

from suds.client import Client
url = 'http://localhost:7789/HelloWordService?wsdl'
client1 = Client(url)
client1.service.say_hello("Dave",5)

结果：

Answer 1

尝试将原语导入到类中：

class HelloWorldService(SimpleWSGISoapApp):
    from soaplib.serializers.primitive import String, Integer, Arraycode
    @soapmethod(String,Integer,_returns=Array(String))
