Android 与 WCF Web 服务使用 ksoap2 - 错误 SoapFault - 故障代码 : ‘a:ActionNotSupported’

Question

我做了一个简单的项目来使用 ksoap2 调用 wcf web 服务。但是当它调用信封.getResponse();它给出了错误的说法————–

“SoapFault – faultcode: ‘a:ActionNotSupported’ faultstring: ‘The message with Action ‘GetString’ cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).’ faultactor: ‘null’ detail: null”

我在本地主机上运行网络服务。

请帮我一些

我分配的值是否正确，

private static final String SOAP_ACTION = “GetString”;
private static final String OPERATION_NAME = “GetString”;
private static final String WSDL_TARGET_NAMESPACE = “http://tempuri.org/”;
private static final String SOAP_ADDRESS = “http://10.0.2.2:14089/Service1.svc?wsdl”;

Answer 1

我们不知道这些值是否正确 - WSDL 应该告诉您调用 GetString 操作的正确 SOAP 操作是什么。

在网络浏览器中打开 WSDL(即您在 SOAP_ADDRESS 中分配的地址)并找到如下内容:

<wsdl:binding name="..." type="...">
  ...
  <wsdl:operation name="GetString">
     <soap:operation soapAction="HERE_IS_CORRECT_ACTION" />
     <wsdl:input>...</wsdl:input>
     <wsdl:output>...</wsdl:output>
  </wsdl>
  ...
</wsdl:binding>

顺便说一句。当您调用该服务时，您应该使用不带 ?wsdl 查询字符串的 URL。
