js代码:
store : Ext.create('Ext.data.Store',{ model : 'portal.model.OperationModel', proxy: { type: 'jsonp',// 使用jsonp url : 'http://192.168.1.38:8080/oorp/getRecentlyAddResource',//远程url reader: { type: 'json', root: 'data' } } }), store.load();
后台java代码:
JSONArray ja = desktopService.getRecentlyAddResource(user); // success(ja); // 回调方法,默认是callback,可以在proxy中通过callbackKey设置 String cb = request.getParameter("callback"); JSONObject result = new JSONObject(); result.put("success", true); result.put("data", ja); response.setContentType("text/javascript"); OutputStreamWriter out = new OutputStreamWriter(response.getOutputStream(), "utf-8"); String str = cb + "(" + result.toString() + ");"; out.write(str); out.flush(); out.close();
其他语言类似,需要返回格式为:
callback({“data”:[{“id”:”my id”}],”success”:true})
