Android WebService 使用小结

适合手机的WebService客户端SDK   KSOAP2:

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

http://files.cnblogs.com/xiaobuild/KSOAP2_SDK.rar

将下载后的jar文件复制到工程的lib目录中（若是没有该目录，能够新建一个，固然，也能够放在其余的目录中）。并在工程中引用这个jar包

如何调用WebService

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

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"   <?xmlversion="1.0"encoding="utf-8"?> <soap:Envelopexmlns: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>     <GetNewsxmlns=" http://tempuri.org/">       <newsid>string</newsid>     </GetNews>   </soap:Body> </soap:Envelope>\

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

 

1 2 3 4 5 6

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

具体代码以下：

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

// 实例化SoapObject对象               SoapObject request =newSoapObject(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");                 // 得到序列化的Envelope 注册Envelope               SoapSerializationEnvelope envelope =newSoapSerializationEnvelope(                       SoapEnvelope.VER11);                              envelope.dotNet =true;               envelope.setOutputSoapObject(request);// envelope.bodyOut=request;                 // HttpTransportSE传输对象               HttpTransportSE transport =newHttpTransportSE(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：

 

  /**

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35
