Python Suds肥皂客户端错误 - 错误请求例外：（400，你＆＃39;错误请求＆＃39;）

Question

我的SOAP网址为202.46.201.237:82/MobilityService.svc?wsdl

这是我的代码：

from suds.client import Client
url_service = 'http://202.46.201.237:82/MobilityService.svc?wsdl'
client = Client(url_service,headers={'Content-Type':    'application/soap+xml', 'charset': 'utf-8'})

print client

      ns2 = "http://tempuri.org/"

            ns1:char
            ns1:duration
            ns1:guid

result = client.factory.create('ns0:WebServiceInputView') 
result.MessageText = 'test'
result.MobileNo = '1234'
result = client.service.AddNomineeDetails(result)

我收到Bad Request Exception: (400, u'Bad Request')错误。我该如何解决这个问题？
