使用Python的WSDL服务,是我的客户端代码还是服务器？

我正在尝试为WSDL服务编写Python客户端.我正在使用Suds库来处理SOAP消息.

当我尝试调用服务时,出现Suds异常：< rval />没有映射到消息部分.如果我设置retxml Suds选项,我将获得对我来说看起来不错的XML.

客户端代码有问题吗？我是否缺少一些允许Suds正确解析XML的标志？或者,问题可能出在服务器上. XML的结构是否正确？

我的代码如下(方法名称已更改)：

c = Client(url)  
p = c.factory.create('MyParam')  
p.value = 100  
c.service.run(p)  

这将导致Suds异常：

File "/home/.../test.py", line 38, in test  
res = self.client.service.run(p)
File "/usr/local/lib/python2.6/dist-packages/suds-0.3.9-py2.6.egg/suds/client.py", line 539, in __call__
return client.invoke(args, kwargs)
File "/usr/local/lib/python2.6/dist-packages/suds-0.3.9-py2.6.egg/suds/client.py", line 598, in invoke
result = self.send(msg)
File "/usr/local/lib/python2.6/dist-packages/suds-0.3.9-py2.6.egg/suds/client.py", line 627, in send  
result = self.succeeded(binding, reply.message)  
File "/usr/local/lib/python2.6/dist-packages/suds-0.3.9-py2.6.egg/suds/client.py", line   659, in succeeded  
r, p = binding.get_reply(self.method, reply)  
File "/usr/local/lib/python2.6/dist-packages/suds-0.3.9-py2.6.egg/suds/bindings/binding.py", line 151, in get_reply  
result = self.replycomposite(rtypes, nodes)  
File "/usr/local/lib/python2.6/dist-packages/suds-0.3.9-  py2.6.egg/suds/bindings/binding.py", line 204, in replycomposite  
raise Exception('<%s/> not mapped to message part' % tag)  
Exception: <rval/> not mapped to message part  

返回的XML(已修改以删除客户标识符)

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
  <S:Body>
    <ns2:getResponse xmlns:ns2="http://api.xxx.xxx.com/api/">
      <rval xmlns="http://xxx.xxx.xxx.com/api/">
        <ns2:totalNumEntries>
          2
        </ns2:totalNumEntries>
        <ns2:entries>
          <ns2:id>
            1
          </ns2:id>
        </ns2:entries>
        <ns2:entries>
          <ns2:id>
            2
          </ns2:id>
        </ns2:entries>
      </rval>
    </ns2:getResponse>
  </S:Body>
</S:Envelope>

解决方法:

可能重复的数字为What does suds mean by “<faultcode/> not mapped to message part”?

这是我对这个问题的回答：

我有一个类似的问题,呼叫成功,并且Suds在解析来自客户端的响应时崩溃.我使用的解决方法是使用Suds option to return raw XML,然后使用BeautifulSoup解析响应.

例：

client = Client(url)
client.set_options(retxml=True)
soapresp_raw_xml = client.service.submit_func(data)
soup = BeautifulStoneSoup(soapresp_raw_xml)
value_i_want = soup.find('ns:NewSRId')
