title: Facebook share url: how to insert custom text at the post?
body: <p>I believe that the answser is simple, but I can't find any useful updated answer.</p>
  
  <p>With Facebook you can easily share a link using this url:</p>
  
  <p><a href="https://www.facebook.com/sharer/sharer.php?u=http://stackoverflow.com" rel="nofollow">https://www.facebook.com/sharer/sharer.php?u=http://stackoverflow.com</a></p>
  
  <p>And with Twitter, you can easily share a tweet using this other format:</p>
  
  <p><a href="https://twitter.com/intent/tweet?text=hello%20this%20is%20a%20tweet" rel="nofollow">https://twitter.com/intent/tweet?text=hello%20this%20is%20a%20tweet</a></p>
  
  <p>(You can click on the links to see the result)</p>

  <p>The thing is, in twitter you can see that I can specify the text of the post directly in the url. But I don't know how to do this on Facebook.</p>
  
  <p>There's a way to do this, with Facebook? I don't want that the user share any URL, but a post with a default text.</p>
  
  <p>Thanks in advance!</p>
