Request.addProperty（「SayHello」，「32」）;不通過32？

Question

我想從android傳遞一個值到aspx web服務。但是，Web服務不採取在下面的代碼中傳遞的32。

Request.addProperty("SayHello", "32"); 

任何幫助將不勝感激。

我的完整的Android代碼如下

package com.example.fp1_webservicedropdown; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.TextView; 

import org.ksoap2.*; 
import org.ksoap2.serialization.SoapObject; 
import org.ksoap2.serialization.SoapPrimitive; 
import org.ksoap2.serialization.SoapSerializationEnvelope; 
import org.ksoap2.transport.*; 

public class MainActivity extends Activity { 
    TextView result; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     result = (TextView) findViewById(R.id.textView2); 

     final String NAMESPACE = "http://sample.com/"; 
     final String METHOD_NAME = "SayHello"; 
     final String SOAP_ACTION = "http://sample.com/SayHello"; 
     final String URL = "http://myLoclalIP/HellowWorld/Service1.asmx"; 

     SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); 
     Request.addProperty("SayHello", "32"); 

     SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
     soapEnvelope.dotNet = true; 
     soapEnvelope.setOutputSoapObject(Request); 

     AndroidHttpTransport aht = new AndroidHttpTransport(URL); 

     try { 
      aht.call(SOAP_ACTION, soapEnvelope); 
      SoapPrimitive resultString = (SoapPrimitive) soapEnvelope.getResponse(); 
      result.setText("The web service returned " + resultString); 
     } 

     catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
} 

我的web服務代碼如下：

[WebService(Namespace = "http://sample.com/")] 
    public class Service1 : System.Web.Services.WebService 
    { 
     [WebMethod] 
     public String SayHello(int a) 
     { 
      int passingValue = 8 + a; 
      String aTemp=passingValue.ToString(); 
      return aTemp; 
     } 


    } 

Answer 1

沒有在文檔的請求類中的任何方法，方法addProperty。雖然您可以將URI構造爲字符串並將其傳遞給構造函數，或使用setDestinationUri(uri)方法。

例如，

uri = "http://www.mydomain.com/index?SayHello=32" 
my_request.setDestinationUri(uri) 

進行更多的控制也有自己設置的HTTP標頭的方法。
