Facebook share button only share the_permalink(), without thumbnail, tilte, excerpt, etc

Question

I'm trying to add socials to my post. I can share the post, but only the post URL. How could I share the post thumbnail, the Title, the excerpt, the author, etc.

This is what i'm trying:

HTML (in single.php):

<div class="share-icons-wrapper">  
    <a href="" onClick="facebookSharer()"><i class="fa fa-facebook share-icon"></i></a>
</div>  

Js

jQuery('.share-icons-wrapper a').click(function(e) {
   e.preventDefault();
});

// Facebook

function facebookSharer(){
window.open( 'https://www.facebook.com/sharer/sharer.php?u='+encodeURIComponent(location.href), 
    'facebookWindow', 
    'width=650,height=350');
    return false;
}   

I don't know wath i'm missing. Thanks.
