我已经检查过发布的与此类似的其他问题,我所看到的都是同样的问题。我将发布这个问题的suds和pysimplesoap。我不关心我上班的哪一个,但我有点需要让其中一个人尽快工作。我认为问题可能在于WSDL是由.NET中创建的服务生成的,因为我遇到了与pysimplesoap和我尝试过的所有其他python soap客户端相同的问题。我用suds和suds-jurko尝试了同样的结果。我对这个SOAP的东西并不擅长(我宁愿使用简单的RESTful服务和JSON)所以任何帮助都会非常感激。我会对我的问题进行投票并标记已接受的解决方案。
这是我的代码:
from suds.client import Client
client = Client('http://url-for-my-service?wsdl')
result = client.service.StartSession('userid','passwd')
以下是我收到的错误消息:
ERROR:suds.client:<suds.sax.document.Document instance at 0x28fcbd8>

我有点像suds更好,因为我可以启用logging.DEBUG并获取更多信息:

答案 0 :(得分:0)
供应商提供了一个工作样本客户端,我可以使用TcpMon运行它,并将发送的XML与suds生成的内容进行比较。事实证明问题是空的<SOAP-ENV:Header/>
标记。
我创建了一个消息插件,用于在发送阶段过滤掉空标题,现在它可以正常工作。这是更新的代码:
import re
from suds.client import Client
from suds.plugin import MessagePlugin
class HeaderFilter(MessagePlugin):
def sending(self, context):
context.envelope = re.sub(r'<[A-Za-z0-9_\-:]*Header/>', '', context.envelope)
return context
client = Client('http://url-for-my-service?wsdl', plugins=[HeaderFilter()])
result = client.service.StartSession('userid','passwd')
我可能更具体而不是使用正则表达式,但我不知道它是否总是使用SOAP-ENV前缀。
