shindig功能接口新增以及调用.doc

Shindig新增功能接口作者：G1创建功能接口处理类(handler),为了结构同一，尽量在org.apache.shindig.social.opensocial.service包中创建2在类前加上以下标注Service(name = appscore, path = /userId+/groupId/appId)，其中name为注册的请求地址，path为参数路径，括号有“+”表示为必选参数。3为handler创建构造器private final AppScoreService service;Injectpublic AppScoreHandler(AppScoreService service) this.service = service;并且声明处理类，在构造器前加Inject注释，让Guice加载时注入4新增方法返回值为Future类型，抛出ProtocolException添加注释Operation(httpMethods = POST, bodyParam = data)httoMethods为http请求类型，body为可选项，用来规定传入数据体名称opensocial标准中，查询httpMethods=GET，创建httpMethods=POST，更新httpMethods=PUT，删除httpMethods=DELETEbodyParam在handler中，可以通过Map map = request.getTypedParameter(data, Map.class);方式获得5在org.apache.shindig.social.core.config.SocialApiGuiceModule类中的protected SetClass getHandlers() return ImmutableSet.Class of(ActivityHandler.class, AppScoreHandler.class, AppDataHandler.class, PersonHandler.class, MessageHandler.class, AlbumHandler.class, MediaItemHandler.class);处添handler处理类6创建Services Interface,规定实现类的方法以及参数目前测试发现，通过js的rpc调用shindig新增功能接口时，不需要新增服务端js代码调用例子： !CDATA function render(myobject) alert(myobject.value); gadgets.window.adjustHeight(); function onload() var getParams = userId: viewer, myParam: this is a example; osapi.appscore.get(getParams).execute(render); gadgets.util.registerOnLoadHandler(onload); 测试1 REST基于json数据格式调用例子：public class Test public static void main(String args) throws Exception send(URL);private static final String URL = http:/app.i8169.local/rest/appscore/me;public static void send(String url) throws Exception HttpURLConnection conn = null;try URL u = new URL(url);conn = (HttpURLConnection) u.openConnection();conn.setDoOutput(true);conn.setDoInput(true);conn.setRequestMethod(PUT);conn.setRequestProperty(Content-type,application/json); OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream();String str = a:d;out.write(str);out.flush();out.close();InputStream input = conn.getInputStream();byte b = new byteinput.available();input.read(b);System.out.println(new String(b);conn.disconnect(); catch (Exception e) e.printStackTrace(); finally if (conn != null) conn = null;注意调用的时候，需要设置Content-typeconn.setRequestProperty(Content-type,application/json);用来规定参数格式类型，目前shindig支持以下格式类型application/json, text/x-json, application/javascript, application/x-javascript, text/javascript, text/ecmascript, application/json-rpc, application/jsonrequest, text/xml, application/xml, application/atom+xml如果shindig发布在tomcat下，需要修改的tomcat
