使用 Soap 服务：如何从 android 发送对此 Web 服务的请求

Question

        This is my coding:

            private static final String METHOD_NAME ="total";

             private static final String NAMESPACE ="http://tempuri.org/";
             private static final String SOAP_ACTION ="http://tempuri.org/total";
             private static final String URL ="http://10.0.2.2:1743/Service1.asmx";
             private TextView tv;
            @Override
            public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);
                tv = (TextView) findViewById(R.id.tv);
                tv.setText(ws());
            }
            private String ws() {
                String result = "";
                try {

                    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);    

                System.out.println("ohaih");
                    request.addProperty("Name","chris");
                    request.addProperty("num1",5);
                    request.addProperty("num2",5);

                    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                            SoapEnvelope.VER11);

                    envelope.dotNet = true;

                    envelope.setOutputSoapObject(request);


                    HttpTransportSE ht = new HttpTransportSE(URL);

                    ht.call(SOAP_ACTION, envelope);
        System.out.println("dfdjssf");

                    if(envelope.getResponse()!=null){
                    //SoapObject response = (SoapObject)envelope.bodyIn;
                        Object response = envelope.getResponse();
                        result = response.toString();
                    }

                } catch (Exception e) {
                    result = e.getMessage();
                }
                return result;
            }
        }

在您的 SOAP 请求中， <validationRequest> 是一种复杂的请求类型，您不能像通常对原始类型那样在request 中添加属性。

您需要创建一个类，其中 extends Vector 和 implements KVMSerializable。

public class ValidationReq extends Vector<String> implements KvmSerializable {


        @Override
        public Object getProperty(int arg0) {
                return this.get(arg0);
        }

        @Override
        public int getPropertyCount() {
                return this.size();
        }

        @Override
        public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
                arg2.name = "string";
                arg2.type = PropertyInfo.STRING_CLASS;
        }

        @Override
        public void setProperty(int arg0, Object arg1) {
                this.add(arg1.toString());
        }

}

您的类将包含您要发送的参数，您需要将该类的对象添加到request。
