Question

我第一次使用suds并尝试与外部公司托管的服务器进行通信。当我在服务器上调用一个方法时，我得到了这个XML。

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <soap:Fault>
      <faultcode>soap:Server</faultcode>

      <faultstring>Can't use string ("") as an ARRAY ref while "strict refs" in use at /vindicia/site_perl/Vindicia/Soap/DocLitUtils.pm line 130.
</faultstring>
    </soap:Fault>
  </soap:Body>
</soap:Envelope>

引发的异常是：


  File "C:\Python26\lib\site-packages\suds-0.4-py2.6.egg\suds\client.py", line 538, in __call__
    return client.invoke(args, kwargs)
  File "C:\Python26\lib\site-packages\suds-0.4-py2.6.egg\suds\client.py", line 602, in invoke
    result = self.send(msg)
  File "C:\Python26\lib\site-packages\suds-0.4-py2.6.egg\suds\client.py", line 634, in send
    result = self.succeeded(binding, reply.message)
  File "C:\Python26\lib\site-packages\suds-0.4-py2.6.egg\suds\client.py", line 669, in succeeded
    r, p = binding.get_reply(self.method, reply)
  File "C:\Python26\lib\site-packages\suds-0.4-py2.6.egg\suds\bindings\binding.py", line 157, in get_reply
    result = self.replycomposite(rtypes, nodes)
  File "C:\Python26\lib\site-packages\suds-0.4-py2.6.egg\suds\bindings\binding.py", line 227, in replycomposite
    raise Exception(' not mapped to message part' % tag)
Exception: 'faultcode' not mapped to message part

知道为什么suds会抛出异常吗？有关它如何修复的任何想法？

Answer 1

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来解析响应。

示例：

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')

Answer 2

这里已经回答：What does suds mean by "<faultcode/> not mapped to message part"?

此异常实际上意味着SOAP-service的答案包含标记<faultcode>，该标记在服务的WSDL方案中不存在。

请记住，suds库缓存了WSDL方案，这就是为什么如果最近更改了WSDL方案可能会出现问题的原因。然后答案与新方案匹配，但由suds-client验证旧方案。在这种情况下，rm /tmp/suds/*会对您有所帮助。

suds是什么意思“<faultcode>没有映射到消息部分”？</faultcode>
