Question

我试图通过Android Eclipse Emulator调用在本地Tomcat服务器上运行的WSDL Web服务。我正在使用KSOAP2发起服务呼叫。

我在尝试获得回复时看到的错误：

SoapFault - faultcode: 'S:Client' faultstring: 'Cannot find dispatch method for {http://localhost:8080/test/}getAllAvailableAssessments' faultactor: 'null' detail: null

有些注意事项：

我已向该应用程序授予INTERNET权限
如果在soapUI
我能够看到WSDL文件给出了它到模拟器浏览器的URL

这是调用webservice的类：

private static String NAMESPACE = "http://localhost:8080/test/";
private static String URL = "http://10.10.10.55:8080/testwebservices/WebServices/AssessmentListingService?wsdl";
private static String METHOD_NAME = "getAllAvailableAssessments";
private static String SOAP_ACTION = "http://localhost:8080/test/getAllAvailableAssessments";

public static String getAllAvailableAssessments()
{
    String webServiceResult = "";

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
    try
    {
        androidHttpTransport.call(SOAP_ACTION, envelope);
        SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
        webServiceResult = response.toString();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

    return webServiceResult;
}

这是wsdl文件：

        </wsdl:input>

        <soap:address location="http://localhost:8080/testwebservices/WebServices/AssessmentListingService" />
    </wsdl:port>
</wsdl:service>

任何想法都会受到赞赏。

Answer 1

SOAP_ACTION变量不必遵循NAMESPACE + METHOD_NAME模式。这些值可以是任何值，具体取决于WSDL结构。

将来自SoapUI的请求XML与来自KSOAP2的转储请求XML进行比较后，我看到了不匹配。

特别是在这种情况下，添加＆＃34;请求＆＃34; SOAP_ACTION变量末尾的字符串解决了问题。

因此，

private static String NAMESPACE = "http://localhost:8080/test/";
private static String URL = "http://10.10.10.55:8080/testwebservices/WebServices/AssessmentListingService?wsdl";
private static String METHOD_NAME = "getAllAvailableAssessments";
private static String SOAP_ACTION = "http://localhost:8080/test/getAllAvailableAssessmentsRequest";
