android - ksoap 2 通信 - 将 asynctask 结果发送到 UI 线程并打印

Question

我正在尝试通过 Visual Studio 将登录凭据从 android 用户发送到在我的本地主机中运行的 C# Web 服务。我使用 KSOAP2 进行 SOAP 通信，并希望将登录信息发送到 Web 服务并在 UI 中打印。我正在使用 AsyncTask 来执行此操作，但无法从 Web 服务获取信息并将其打印到 android UI。

有人可以帮助我哪里出错了吗？？？？？？

public class MainActivity extends Activity {

    EditText un,pw;
    TextView tv;
    Button test;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button test=(Button) findViewById(R.id.login);
        un = (EditText) findViewById(R.id.et_un);
        pw = (EditText) findViewById(R.id.et_pw);


            test.setOnClickListener(new View.OnClickListener(){

                @Override
                public void onClick(View v) {
                    FileAsync fleasyn= new FileAsync(null);
                    fleasyn.execute();
                    } 
                }); 
 }
}



class FileAsync extends AsyncTask<String, String, char[]> {
   public FileAsync(String quotes) 
{


}


private char[] resultstring;
private TextView tv;

@Override
protected void onProgressUpdate(String... progress) {


}

protected void onPostExecute(String unused) {
    tv.setText("Status:"+resultstring);
                System.out.println(resultstring);
}


@Override
protected char[] doInBackground(String... params) {

    final String NAMESPACE = "http://sparking.org/login";
    final String METHOD_NAME = "login";
    final String SOAP_ACTION = "http://sparking.org/login";
    final String URL = "http://localhost:63734/service.asmx";

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    HttpTransportSE transport = new HttpTransportSE(URL);
    try {
    transport.call(SOAP_ACTION, envelope);
    SoapPrimitive resultstring = (SoapPrimitive)envelope.getResponse();

}

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

}

首先，您需要分配这些变量：

`final String NAMESPACE = "http://xyz.org/";`
`final String METHOD_NAME="";`
`final String SOAP_ACTION="";`
`final String URL = "http://localhost:63734/mywbservice.asmx";**strong text**`

METHOD_NAME 和 SOAP_ACTION 不能为空。以下是项目所需的值：

<SOAP_ACTION="http://spartansparking.org/login";>
<METHOD_NAME="login";>
<NAMESPACE="http://spartansparking.org/";>
<URL = "http://localhost:63734/parkingservice.asmx";>

要调用 WebService .NET，实际上不需要使用 AsyncTask。您可以使用用户主线程。

如果您在模拟器和本地主机上工作，请尝试使用 10.0.2.2 作为本地主机，例如：set URL ="http://10.0.2.2/parkingservice.asmx";>

如果你得到java.net.SocketException: socket failed: EACCES (Permission denied)

也许你应该检查你的许可：

<uses-permission android:name="android.permission.INTERNET" />
