如何在 android 中处理 SOAP 请求和响应

Question

我正在开发一个应用程序，我在其中使用 SOAP 请求和响应来处理 Web 服务。谁能告诉我如何处理 SOAP 请求和响应？我已经阅读了一些教程，但这些教程并没有被清楚地理解。 Click here

public class StockQuoteFetcher {

    private final String NAMESPACE = "https://book.mylimobiz.com/api";
    private final String METHOD_NAME = "GetCars";
    private final String SOAP_ACTION ="https://book.mylimobiz.com/api/GetCars";
    private final String URL = "https://book.mylimobiz.com/api/ApiService.asmx?WSDL";
    private final SoapSerializationEnvelope envelope;

    public StockQuoteFetcher(String apiId, String apikey)
    {
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        PropertyInfo quotesProperty = new PropertyInfo();
        quotesProperty.setName("apiId");
        quotesProperty.setValue(apiId);
        quotesProperty.setType(String.class);
        request.addProperty(quotesProperty);
        PropertyInfo quotesProperty1 = new PropertyInfo();
        quotesProperty1.setName("apiKey");
        quotesProperty1.setValue(apikey);
        quotesProperty1.setType(String.class);
        request.addProperty(quotesProperty1);

        envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
    }

    public  List<Car> fetch()
    {
        HttpTransportSE httpRequest = new HttpTransportSE(URL);
        Handler quoteParser = new Handler();;
        try
        {
            httpRequest.call(SOAP_ACTION, envelope);
            SoapObject resultsString = (SoapObject) envelope.getResponse();
            Xml.parse(resultsString.toString(), quoteParser);
            //result =  resultsString.toString();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        return quoteParser.getCar();
    }
}

public class Handler extends DefaultHandler {

    private ArrayList<Car> quotes = new ArrayList<Car>();
    private Car currentQuote;
    private String currentNodeText;

    private final String CAR = "Car";
    private final String CAR_ID = "CarId";
    private final String CAR_CODE = "CarCode";
    private final String CAR_NAME = "CarName";
    private final String CAR_TYPE = "CarType";
    private final String CELL_PHONE = "CellPhone";
    private final String TWO_WAY_RADIO_ID = "TwoWayRadioId";

    @Override
    public void startElement(String uri, String localName, String qName,
            Attributes attributes) throws SAXException {
        // Create a new StockQuote for every corresponding
        // <Stock> node in the XML document
        if (localName.equalsIgnoreCase(CAR)) {
            currentQuote = new Car();
        }
    }

    @Override
    public void characters(char[] ch, int start, int length)
            throws SAXException {
        // Retrieve the text content of the current node
        // that is being processed
        currentNodeText = new String(ch, start, length);
    }

    @Override
    public void endElement(String uri, String localName, String qName)
            throws SAXException {
        if(localName.equalsIgnoreCase(CAR_ID)){
            currentQuote.setCarId(CAR_ID);
        }else if(localName.equalsIgnoreCase(CAR_TYPE)){
            currentQuote.setCarType(CAR_TYPE);
        }else if(localName.equalsIgnoreCase(CAR_NAME)){
            currentQuote.setCarName(CAR_NAME);
        }else if(localName.equalsIgnoreCase(CAR)){
            // When the </Stock> element is reached, this quote object is complete.
            quotes.add(currentQuote);
        }
    }

    public ArrayList<Car> getCar()
    {
        return quotes;
    }
}

你应该使用kSOAP2 jar。它的文档是here。

要调用网络服务，请使用以下行

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
SoapObject request = new SoapObject(NAMESPACE, METHOD);
//bodyOut is the body object to be sent out with this envelope
envelope.bodyOut = request;
HttpTransportSE transport = new HttpTransportSE(URL);
transport.call(NAMESPACE + SOAP_ACTION_PREFIX + METHOD, envelope); 

envelope.bodyOut 用于将soap body 发送到web 服务，envelop.bodyIn 用于接收来自web 服务的响应。

SoapPrimitive resultSOAP = (SoapPrimitive) ((SoapObject) envelope.bodyIn).getProperty(0);
response=resultSOAP.toString();
