Facebook Sharer没有显示正确的描述

[英]Facebook Sharer doesn't display correct description

原文 2014-05-31 12:20:21 2 1 php/ facebook/ facebook-graph-api

I'm building a very simple generate-and-share web app (www.startupgenerator.eu). 我正在构建一个非常简单的生成和共享Web应用程序（www.startupgenerator.eu）。 I'm using classic sharer.php FB tool. 我正在使用经典的sharer.php FB工具。

I'm passing a value (c) via QueryString. 我通过QueryString传递值（c）。 This is the encrypted phrase that will be displayed as value for meta description and open graph og:description. 这是加密短语，将显示为元描述和打开图og：description的值。 Moreover; 此外; if a value is present in c variable, the og:title will contain a different value. 如果c变量中存在值，则og：title将包含其他值。

Anyway, it doesn't work with fb sharer. 无论如何，它与fb sharer不兼容。 When a user opens the sharer popup (via clicking the share button on the website; or via direct paste in his timeline), Facebook loads only the standard description and the standard title. 当用户打开共享器弹出窗口（通过单击网站上的共享按钮；或通过在其时间轴中直接粘贴）时，Facebook仅加载标准描述和标准标题。 It seems like FB has already cached the values, and doesn't make the request with the "custom" c query string value. 似乎FB已经缓存了值，并且没有使用“自定义” c查询字符串值发出请求。

How come? 怎么会？ Thanks in advance for help. 在此先感谢您的帮助。
