Android中调用Web Services

<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>
