Question

我使用.Net C＃创建了Web服务。现在我试图从Android应用程序访问它，所以我尝试使用KSOAP2。

这是我的代码。

final String NAMESPACE = "http://tempuri.org/";
final String METHOD_NAME = "HelloWorld";
final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
final String URL = "http://localhost:61252/Service1.asmx"; 

new Thread() {

 public void run() {
                     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
                     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                     SoapEnvelope.VER11);
                     envelope.dotNet=true;
                     envelope.setOutputSoapObject(request);
                     HttpTransportSE  httpTransport = new HttpTransportSE(URL);
                     httpTransport.debug = true;
                     try {
                      httpTransport.call(SOAP_ACTION, envelope);
                      SoapObject result = (SoapObject) envelope.bodyIn;

                     }
                     catch (Exception e) {
                         // TODO: handle exception
                    }}}.start();

但是在这一行

httpTransport.call(SOAP_ACTION, envelope);

它将进入catch块并且没有任何错误消息。

我也发现了很多关于这方面的问题，但由于我是新手，因此无法找到我的错误。

我做得对还是有其他方法可以使用？

Answer 1

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
// if required you can use addProperty to add properties in url
            request.addProperty("User", "abcd@gmail.com");
            request.addProperty("Password", "abcd");
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.headerOut = new Element[1];
            envelope.headerOut[0] = buildAuthHeader();
            envelope.dotNet = true;
            envelope.setOutputSoapObject(request);

            // if you want to add any property you can add here.

            /*
             * PropertyInfo cityProp = new PropertyInfo();
             * 
             * cityProp.setType(String.class); request.addProperty(cityProp);
             */

            Log.e("value of request", request.toString());
            Log.e("Value of envolope ", envelope.toString());

            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    // add try catch block.
            try {

                androidHttpTransport.call(SOAP_ACTION, envelope);
                Log.i("myAppEnvelope", envelope.toString());

                SoapObject response = (SoapObject) envelope.getResponse();
    // There are two types of Soap response (as per my knowledge or use )
    // SoapObject or SoapPrimitive  so check what is your response and use accordingly.

    SoapObject data = (SoapObject) response
                        .getProperty("field_name");

    // OR 

    SoapPrimitive data = (SoapPrimitive) data.getProperty("field_name");

Answer 2

 SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);        
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
     envelope.setOutputSoapObject(request);

     HttpTransportSE ht = new HttpTransportSE(URL);
     ht.call(SOAP_ACTION, envelope);
     final  SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
     final String str = response.toString();

将此用于reference。希望这会对你有所帮助。
