Android中调用Web Services

jopen 13年前
     <p>Android中调用Web Services有很多方法,我们现在使用的是ksoap,它是SOAP web services的客户端包,ksoap现在版本为2.0.它的一个主要优点就是对dotNET兼容性比较不错。</p>    <p>首先下载ksoap的包文件,在Eclispe的Package Explorer中右键项目,Build Path>Add Libraries,找到ksoap2-android-assembly-2.4-jar-with-dependencies.jar添加该引用。代码如下:</p>    <pre class="brush:java; toolbar: true; auto-links: false;">public class WSHelper {     final static String WSUrl="http://xxx/WSUrl.asmx";       private static String namespace = "http://tempuri.org/";     /*************************************      * 获取web services内容      * @param url      * @param params      * @return      *************************************/     public static String GetResponse(String method,List<BasicNameValuePair> params){                   try {             String url = WSUrl;             SoapObject request = new SoapObject(namespace, method);             for(int i=0,len=params.size();i<len;i++){                 request.addProperty(params.get(i).getName(), params.get(i).getValue());             }             SoapSerializationEnvelope envelope =                  new SoapSerializationEnvelope(SoapEnvelope.VER11);              envelope.dotNet = true;              envelope.setOutputSoapObject(request);                            AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(url);              androidHttpTransport.call(namespace + method, envelope);                            SoapPrimitive result = (SoapPrimitive)envelope.getResponse();              return result.toString();         } catch (Exception e) {             return "Error:calling the web services error";         }     } } </pre>调用时代码如下:    <pre class="brush:java; toolbar: true; auto-links: false;">String method = "MethodName";//方法名称 List<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>(); params.add(new BasicNameValuePair("userId", String.valueOf(1995))); return WSHelper.GetResponse(method,params); </pre>    <p></p>    <p>这里参数可以定义多个,返回时是以String类似来返回。</p>    <p>注意由于我们调用Web sevices,就需要程序有访问网络的权限,因此需要在AndroidManifest.xml中manifest节中增加访问网络权限的定义:</p>    <pre class="brush:xml; toolbar: true; auto-links: false;"><uses-permission android:name="android.permission.INTERNET"></uses-permission></pre>文章出处:    <a href="/misc/goto?guid=4959499727498018247" rel="nofollow">http://www.cnblogs.com/walkingp/archive/2011/04/05/2006193.html</a>    <p></p>    <p></p>
