salesforce - 如何将linkedin feed数据获取到salesforce中的visualforce页面

Question

我正在尝试将 LinkedIn 集成到 salesforce 上，我已经成功授权，获得了 accessToken 并将我的个人资料信息放入 visulforce 页面并将提要发布到linkedin ....现在我想将提要输入 vf 页面我怎么能得到？这是我的getfeed方法代码

method(){
Http http = new Http();
        HttpRequest httpReq = new HttpRequest();
        HttpResponse httpRes = new HttpResponse();
        httpReq.SetMethod('GET');
        httpReq.setHeader('Authorization', 'Bearer '+linkedlnInfoList[0].Access_Token__c);
        httpRes.setHeader('Connection', 'Keep-Alive');
        httpReq.setEndpoint('https://api.linkedin.com/v2/activityFeeds?q=networkShares&count=2');
        try{
            httpRes = http.send(httpReq);
            if(httpRes.getStatusCode() == 200){

               // Map<String,object> data = (Map<String,object>)JSON.deserializeUntyped(httpRes.getBody());              
                 String response=httpRes.getBody();

            }

错误未知属性控制器。响应或数据
