SoapFault - faultcode：'soap:Server‘faultstring：’服务器无法处理未设置为对象实例的request.Object引用

Question

我有一个用asp.net编写的have服务。我想从安卓应用程序使用SOAP(ksoap2)访问webservice。

这是我的soap片段，

//Namespace of the Webservice - can be found in WSDL
private static String NAMESPACE = "http://tempuri.org/";
//Webservice URL - WSDL File location
private static String URL = "http://locationbasedapp.net/Service1.asmx";//Make sure you changed IP address
//SOAP Action URI again Namespace + Web method name
private static String SOAP_ACTION = "http://tempuri.org/";

public static String invokeListLocationsWS(String datetext, String webMethName) {
    String xmlDataSet = "";
    // Create request
    SoapObject request = new SoapObject(NAMESPACE, webMethName);
    // Property which holds input parameters
    PropertyInfo datetextPI = new PropertyInfo();
    PropertyInfo passPI = new PropertyInfo();
    // Set Username
    datetextPI.setName("datetext");
    // Set Value
    datetextPI.setValue(datetext);
    // Set dataType
    datetextPI.setType(String.class);
    // Add the property to request object
    request.addProperty(datetextPI);

    // Create envelope
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    envelope.dotNet = true;
    // Set output SOAP object
    envelope.setOutputSoapObject(request);
    // Create HTTP call object
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        // Invoke web service
        androidHttpTransport.call(SOAP_ACTION+webMethName, envelope);
        // Get the response
        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
        // Assign it to  boolean variable variable

        xmlDataSet =response.toString();

    } catch (Exception e) {
        //Assign Error Status true in static variable 'errored'
        MapActivity.errored = true;
        e.printStackTrace();
    }
    //Return booleam to calling object
    return xmlDataSet;
}

当我调试代码时，我有一个问题标题中提到的错误。错误显示在

SoapPrimitive response = (SoapPrimitive)envelope.getResponse();

线路..。

我想我得不到webservice的响应。我怎么才能修复它？

Webservice返回xml.InnerText。它是字符串类型。

请回答我。

虽然我不是.NET开发人员，但我在使用Java之前见过类似的错误代码，它总是归结为调用web service返回的XML无效。

在我的例子中，我尝试捕获原始XML响应，然后尝试使用XML解析库解析它。
