How to pass a parameter like title, summary and image in a Facebook sharer URL

Looks like Facebook disabled passing parameters to the sharer.

We have changed the behavior of the sharer plugin to be consistent with other plugins and features on our platform.

The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post from the url OG meta tags.

Here's the URL to the post: https://developers.facebook.com/x/bugs/357750474364812/

The only parameter you need right now is ?u=<YOUR_URL>. All other data will be fetched from page or (better) from your open graph meta tags:

<meta property="og:url"                content="http://www.nytimes.com/2015/02/19/arts/international/when-great-minds-dont-think-alike.html" /><meta property="og:type"               content="article" /><meta property="og:title"              content="When Great Minds Don’t Think Alike" /><meta property="og:description"        content="How much does culture influence creative thinking?" /><meta property="og:image"              content="http://static01.nyt.com/images/2015/02/19/arts/international/19iht-btnumbers19A/19iht-btnumbers19A-facebookJumbo-v2.jpg" />

Example & description here

You can test your page for accordance in the debugger.

This works at the moment (Oct. 2016), but I can't guarantee how long it will last:
