未连接到Android KSOAP Webservice

时间：2014-05-15 05:01:57

标签： android web-services ksoap2

我的localhost上有一个web服务，它有一个连接数据库的简单方法，并且还返回字符串数组中的城市名称。

以下是我运行服务时的链接：

http://localhost:1543/Service1.asmx

我尝试通过Android应用程序连接到此网络服务，但我认为我没有正确选择namespace或soapaction等等，所以我收到以下内容异常。

预期：START_TAG {http://schemas.xmlsoap.org/soap/envelope/}信封（位置：START_TAG @ 2：7 in java.io.InputStreamReader@41387778）

这是我的Android代码：

    public class ProvinceCityActivity extends Activity
{
    EditText txtProvince;
    Button btnResult;

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

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

    private static String URL = "http://192.168.0.109:1543/Service1.asmx";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        txtProvince = (EditText) findViewById(R.id.txtProvince);
        btnResult = (Button) findViewById(R.id.btnResult);
        btnResult.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
                request.addProperty("value", txtProvince.getText().toString());
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                        SoapEnvelope.VER11);
                envelope.setOutputSoapObject(request);
                envelope.dotNet = true;


                try
                {
                    HttpTransportSE androidHttpTransport = new HttpTransportSE(
                            URL);
                    androidHttpTransport.call(SOAP_ACTION, envelope);


                    SoapObject result = (SoapObject) envelope.bodyIn;
                    if (result != null)
                    {
                        String[] strResult = (String[]) result.getProperty(0);
                    Toast.makeText(getApplicationContext(),
                            "Cities: " + strResult[0], 6000).show();
                    }
                } catch (Exception e)
                {
                    Toast.makeText(getApplicationContext(),
                            e.getMessage().toString(), 6000).show();
                }

            }
        });

    }
}

见图像

enter image description here

SOAP_ACTION ：这是您的NAMESPACE / METHOD_NAME，例如“http://ws.android4.com”

METHOD_NAME ：这是方法的名称，例如：“sayHello”

NAMESPACE ：这是你的NameSapce，例如：“http://ws.android4.com”

对于示例网络服务，请参阅此webservice of w3schools

下面，

METHOD_NAME：CelsiusToFahrenheit

SOAPAction：http://www.w3schools.com/webservices/CelsiusToFahrenheit

NAMESPACE：http://www.w3schools.com/webservices/

向Androidanifest.xml文件添加Internet权限。

您是否从Android模拟器调试您的应用程序？如果是这样，您应该使用“http：// 10.0.2.2”启动您的URL，以便模拟器可以连接到您的本地Web服务......

试试这个在我的本地机器上工作。如果成功添加活动，Webservice将返回true。我希望它会对你有所帮助。

我会把我的修补程序扔到那里......我已经多次遇到这种情况，而且过去每次都是行动或方法或网址。但是，这次它是一个奇怪的URL ...

我正在浏览当前项目的代理。出于某种原因，URL区分大小写。

https://abc.gov/webservice/webservice.asmx有效

https://abc.gov/WEBSERVICE/webservice.asmx无法正常工作

希望这会有所帮助。

答案 4 :(得分：-1)

如果您未提供正确的网址，则会出现此错误。请检查您托管Web服务的Web服务的URL，方法名称和Soap Action。使用像AsyncTask这样的后台服务来调用webservices是一种很好的做法。
