Question

这个问题与以下内容有关： Python SOAP server / client

对于使用python的soap，建议使用soaplib（http://wiki.github.com/jkp/soaplib）作为soap服务器，并使用suds（https://fedorahosted.org/suds/）作为soap客户端。我的目标是在python中创建可由多个客户端（java等）使用的soap服务。我尝试了soaplib（http://trac.optio.webfactional.com/wiki/HelloWorld）的HelloWorld示例。当客户端也使用soaplib时，它运行良好。

然后，我尝试使用suds作为消费HelloWorld服务的客户端，但它失败了。 - 为什么会这样？ soaplib服务器是否有不同客户端使用的问题？

这里是服务器的代码：

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：

尝试将基元导入您的班级：

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