尝试使用客户端 jquery 和 ajax 更新 Facebook Open Graph 元标记 [英] Trying to update Facebook Open Graph meta tags using client side jquery and ajax
问题描述
我使用 ajax 来呈现一个内容页面,其中包含一个 Facebook Like Button 插件.
I use ajax to render a content page with a Facebook Like Button plugin in it.
问题是当用户点击 Like 时,Facebook 会提取元信息,但我不知道如何使用 ajax 分配元信息.
The problem is that when the user clics Like, Facebook will extract meta info but I don't know how to assign the meta with ajax.
我尝试使用 append to head int FB.init 但它似乎不起作用并且当用户喜欢 Facebook 上的页面时更新没有反映
I tried using append to head int FB.init but it seems to not work and the update isn't reflected when users like the page on Facebook
$('head').append("<meta property="og:title" content="The Rock"/>');

当然这行不通,因为 Facebook 的抓取工具从您的服务器请求您的 URL – 并且不关心 DOM 当前在任何用户的浏览器.
Of course this does not work, because Facebook’s scraper requests your URLs from your server – and does not care about what the DOM might currently look like in any user’s browser.
您不能在客户端添加开放图谱元数据.
You can not add Open Graph meta data client-side.
