將數組傳遞到SOAP Web服務以插入遠程數據庫

Question

我想使用可用的ksoap庫將我的Android應用程序中的數組傳遞給SOAP Web服務。

我的數組是這樣的：

String[] values={"abc","def"}; 

如何通過這個作爲參數傳遞給我的web服務調用？

任何人都可以幫我嗎？

這是我的web服務代碼：

public class Service1 : System.Web.Services.WebService 
    { 
    [WebMethod] 

    public String getnames(String[] values) 
    { 

     try 
     { 

      using (SqlConnection myConnection = new SqlConnection(@"Data Source=.\SQLEXPRESS;Initial Catalog=student;User ID=sa;Password=123")) 
      { 
       int count = 1; 
       int rows = 0; 

       myConnection.Open(); 
       foreach (string student in values) 
       { 
        count++; 
        using (SqlCommand myCommand = new SqlCommand()) 
        { 
         myCommand.Connection = myConnection; 
         myCommand.CommandText = "insert into record values(@pCount, @pStudent)"; 
         SqlParameter param = myCommand.CreateParameter(); 
         param.ParameterName = "@pCount"; 
         param.Value = count; 
         myCommand.Parameters.Add(param); 

         param = myCommand.CreateParameter(); 
         param.ParameterName = "@pSudent"; 
         param.Value = student; 

         rows = myCommand.ExecuteNonQuery(); 
        } 
       } 
      } 
     } 

     catch (Exception ex) 
     { 
      Console.WriteLine(ex.Message); 
      return "an error occured"; 
     } 


     return "success"; 
     } 
    } 
    } 

我的logcat：

這是閱讀SOAP的Web服務的示例代碼，希望這會幫助你，

private static String SOAP_ACTION = "http://tempuri.org/HelloWorld"; 

private static String NAMESPACE = "http://tempuri.org/"; 
private static String METHOD_NAME = "HelloWorld"; 

private static String URL = "http://bimbim.in/Sample/TestService.asmx?WSDL"; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    //Initialize soap request + add parameters 
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);   

    //Use this to add parameters 
    request.addProperty("Parameter","Value"); 

    //Declare the version of the SOAP request 
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
    envelope.setOutputSoapObject(request); 

    //Needed to make the internet call 
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
    try { 
     //this is the actual part that will call the webservice 
     androidHttpTransport.call(SOAP_ACTION, envelope); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

    // Get the SoapResult from the envelope body. 
    SoapObject result = (SoapObject)envelope.bodyIn; 

    if(result != null){ 
     TextView t = (TextView)this.findViewById(R.id.resultbox); 

     //Get the first property and change the label text 
     t.setText("SOAP response:\n\n" + result.getProperty(0).toString()); 
    } 

}

這是Android庫KSOAP2的一個已知問題，它目前根本不支持數組。問題的描述是在這裏：

序列化到JSON或XML，發送JSON或XML服務器，解碼服務器上的JSON或XML。不確定你在案件中使用的確切方法。
