Is there a simple Facebook “Like” or share URL?

问题

Is there a simple URL string that Facebook will accept to "like" a site... or more accurately (as a commenter points out below), share a site? As a comparison, Twitter allows you to post from any page simply by pointing an anchor at a customized URL... like this:

<a href="https://twitter.com/share?text=Check%20out%20this%20site:&url=http://example.com">Tweet this!</a>

I can't seem to find anything in the Facebook documentation.

Not exactly an answer, but close enough for me:

http://www.facebook.com/sharer.php?u=http://mysite.com/

That'll do it.

There is a non-depreciated equivalent to the twitter or sharer.php functionality, though it is way more annoying. This doesn't exactly answer the question about "liking" a page but does accomplish the exact analogy to the twitter share, which seems to be what the question is asking.

https://developers.facebook.com/apps/ - make a new app with a developer account.
Make the Display Name the name of your business or website
add your domain without http under App Domains
add your base URL under Website with Facebook Login (with http )
Grab the App ID

Now make your url like this:

http://www.facebook.com/dialog/feed?app_id=000000000000000&link=http://example.com/whatever&redirect_uri=http://example.com/backtothesite

You would think the redirect_uri would default to the user's facebook home or to the link parameter, but it's a required field.

More parameters here: http://developers.facebook.com/docs/reference/dialogs/feed/

No, Facebook only permits Liking a page via a Like button.

回答4:

At the bottom of this page:

http://developers.facebook.com/docs/share/

Feel free to create your own implementation based on this.

回答5:

There is a way how to do it, but not very comfortable for users, because they must click on 'like' button twice.

https://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fexample.com%2F

http%3A%2F%2Fexample.com%2F is url encoded version of http://example.com/ .

Or you can place this link into iframe and then only one click is needed for liking of url

It's a little more verbose with Facebook to do the same thing.

<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId={YOUR_APP_ID}";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

<div class="fb-like" 
    data-href="http://mysite.com" 
    data-send="true" 
    data-width="450" 
    data-show-faces="true">
</div>
