我正在尝试使用python SUDS调用Web服务方法。
当尝试创建特定的复杂类型时，SUDS会向其添加xsi:type="ns0:DeedDto"。
创建除此之外的其他类型，SUDS不会附加xsi：type。
这里的问题是接收端无法识别此类型，然后我得到此（特定）错误：
WebFault: Server raised fault: 'Unable to cast object of type 'ServiceProxy.DeedDto' to type 'ServiceProxy.DeedDto[]
以下是WSDL URL
以下是实际代码：

看到这是我刚刚添加的已经构建的解决方案，我需要坚持使用SUDS。 否则我可能会看别的东西。
答案 0 :(得分：0)
我使用这个（稍微愚蠢的）解决方案修复了它：
self.client = Client(self.wsdl, plugins=[XSIValidator()])
class XSIValidator(MessagePlugin):
""" Handles WSDL object differences """
def sending(self, context):
context.envelope = context.envelope.replace(
' xsi:type="ns0:DeedDto"', '')
