適合手機的WebService客戶端SDK KSOAP2: java

將下載後的jar文件複製到工程的lib目錄中（若是沒有該目錄，能夠新建一個，固然，也能夠放在其餘的目錄中）。並在工程中引用這個jar包 ui

如何調用WebService google

打開webServic連接，如http://macau.sanvio.net/ReadOrderWebService/wsReadOrder.asmx?op=GetNews spa

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>\

根據該xml肯定命名空間，調用方法， webServer地址，調用參數等 .net

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