Android KSoap2 Webservice使用问题

Question

我正在使用 Ksoap2 将以下代码用于 Web 服务，

package com.google.android.myWebService;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpsTransportSE;
//import org.ksoap2.transport.HttpTransport;

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

public class myWebService extends Activity {
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://www.webservicex.net/GetWeatherByPlaceName";
    private static final String METHOD_NAME = "GetWeatherByPlaceName";
    private static final String NAMESPACE = "http://www.webservicex.net";
    private static final String URL = "http://www.webservicex.net/WeatherForecast.asmx?WSDL";
    private Object resultsRequestSOAP = null;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        TextView tv = new TextView(this);
        setContentView(tv);

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        // SoapObject
        request.addProperty("PlaceName", "new york");
        //request.addProperty("lastname", "Williams");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);
        Log.d(null,"Status : set HttpTransport");


        HttpsTransportSE androidHttpTransport = new HttpsTransportSE(URL, 443, "", 5000);
        try {
            Log.d(null,"Status : b4 Call");
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Log.d(null,"Status : Call done");
            resultsRequestSOAP = envelope.getResponse();
            Log.d(null,"Status : Response received");
            String[] results = (String[]) resultsRequestSOAP;
            tv.setText(results[0]);
        } catch (Exception aE) {
            //aE.printStackTrace();
            Log.d(null,"Exception: " + aE);
        }
    }
}

但它在 logcat 中给出以下输出：

我的代码有什么问题？

Answer 1

对此有几个答案 问题已经在这里。如果 ksoap2 仍然对尾部斜杠敏感，第二个链接可能是您的答案。

Answer 2

这是一个.Net Web服务，您需要

envelope.dotNet = true;

在执行请求之前进行设置。

Answer 3

这不是一个错误，只是关于 kxml2 和 xmlpull 类验证的警告。

您将为您的项目导入 ksoap2.jar 库来进行构建。但是 ksoap2.jar 库里面有 kxml2 和 xmlpull jar。这些 jar 已经包含在 Android 操作系统中。因此 DexOpt 实用程序无法验证 apk 二进制文件中的库。别担心。操作系统只会使用它自己的 kxml2 和 xmlpull 库，但不会使用您的。
