android WebService

适合手机的WebService客户端SDK   KSOAP2:

http://code.google.com/p/ksoap2-android/downloads/list

将下载后的jar文件复制到工程的lib目录中（如果没有该目录，可以新建一个，当然，也可以放在其他的目录中）。并在工程中引用这个jar包

如何调用WebService

打开webServic链接，如http://macau.sanvio.net/ReadOrderWebService/wsReadOrder.asmx?op=GetNews

POST /ReadOrderWebService/wsReadOrder.asmx HTTP/1.1
Host: macau.sanvio.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/GetNews"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetNews xmlns="http://tempuri.org/">
      <newsid>string</newsid>
    </GetNews>
  </soap:Body>
</soap:Envelope>

根据该xml确定命名空间  ，调用方法， webServer地址，调用参数等

    // 命名空间
    private static final String ServiceNameSpace = "http://tempuri.org/";
    // webServer地址
    private static final String webServiceUrl = "http://macau.sanvio.net/ReadOrderWebService/wsReadOrder.asmx";
    //webServer调用方法名
    private static final String GetNews = "GetNews";

具体代码如下：

                // 实例化SoapObject对象
                SoapObject request = new SoapObject(ServiceNameSpace, GetNews);
                // 有参数的话,设置调用方法参数 request.addProperty("参数名称","参数值");
                request.addProperty("newsid", "0001");

                // 获得序列化的Envelope 注册Envelope
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                        SoapEnvelope.VER11);                
                envelope.dotNet = true;
                envelope.setOutputSoapObject(request);// envelope.bodyOut=request;

                // HttpTransportSE传输对象
                HttpTransportSE transport = new HttpTransportSE(webServiceUrl);                
                transport.debug = true;

                // 调用
                try {
                    transport.call(ServiceNameSpace + GetNews, envelope);
                    if (envelope.getResponse() != null) {

                        System.out.println("Get Info is finisth!");
                        // System.out.println(envelope.bodyIn.toString());
                        // parseNews(envelope.bodyIn.toString());
                        //write(envelope.bodyIn.toString(), "001.txt");
　　　　　　　　　　　　　　 //解析xml
                        parseNews(envelope);

                    }

                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (XmlPullParserException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

一层一层遍历信息：

    /**
     * 
     * SoapSerializationEnvelope准换为SoapObject 遍历SoapObject 解析xml
     * 
     * @param envelope
     * @throws IOException
     */
    public void parseNews(SoapSerializationEnvelope envelope) {
        strResult = "";
        SoapObject soapObject = (SoapObject) envelope.bodyIn;
        for (int i = 0; i < soapObject.getPropertyCount(); i++) {

            SoapObject soapChilds = (SoapObject) soapObject.getProperty(i);
            for (int j = 1; j < soapChilds.getPropertyCount(); j++) {

                SoapObject soapChilds2 = (SoapObject) soapChilds.getProperty(j);
                for (int k = 0; k < soapChilds2.getPropertyCount(); k++) {

                    SoapObject soapChilds3 = (SoapObject) soapChilds2
                            .getProperty(k);
                    for (int l = 0; l < soapChilds3.getPropertyCount(); l++) {
                        SoapObject soapChilds4 = (SoapObject) soapChilds3
                                .getProperty(l);
                        strResult += soapChilds4.getPropertyCount()+"   "+soapChilds4.getAttributeCount()
                                + "\n========================================\n";
                        for (int n = 0; n<soapChilds4.getPropertyCount(); n++) {                            
                            strResult += "\n"+soapChilds4.getProperty(n);
                        }

                    }
                }
            }

        }
        showTextView.setText(strResult);
    }
