流星HTTP.call（「get」）迴應

我試圖從各種網站，如標題和說明拉基本信息。我可以成功獲取響應對象，而我得到的是整個網站的HTML。我一直在玩HTTP.call方法中的選項，但無法弄清楚如何僅從響應對象返回我想要的。這裏有兩個因素我想獲得：流星HTTP.call（「get」）迴應

<meta property="og:description" content="Our unique teaching style lets students develop their creative potential while learning solid computing skills.">

和

<meta property="og:site_name" content="Goldsmiths, University of London">

我可以通過搜索結果爲<title></title>拿到冠軍很容易的，但必須使用PARAMS是一個更好的方法或呼叫方法選項中的數據。

Meteor.methods({ 
    getInfo: function (url) { 
     HTTP.call('GET', url, {}, function (error, result) { 
      if (!error) { 
       //console.log(result); 
       var titleStart = result.content.toLowerCase().indexOf('<title>'), 
        titleEnd = result.content.toLowerCase().indexOf('</title>'), 
        titleText = result.content.substring(titleStart + '<title>'.length, titleEnd)}
