Facebook Open Graph Watch action

问题:

I'm trying to make a Facebook video application so users can have a video stored on my site displayed on their wall using Facebook Open Graph.

I'm using the below code for user login.

<script>
    window.fbAsyncInit = function() {
        FB.init({
            appId      : 'MYAPPID', // App ID
            status     : true, // check login status
            cookie     : true, // enable cookies to allow the server to access the session
            xfbml      : true  // parse XFBML
        });
    };

    // Load the SDK asynchronously
    (function(d){
        var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
        js = d.createElement('script'); js.id = id; js.async = true;
        js.src = "//connect.facebook.net/en_US/all.js";
        d.getElementsByTagName('head')[0].appendChild(js);
    }(document));
</script>

Now how do I implement the Watch action?

curl -F 'access_token=myaccesstoken' \
 -F 'movie=http://samples.ogp.me/453907197960619' \
    'https://graph.facebook.com/me/video.watches'

And this

curl 'https://graph.facebook.com/me/video.watches?access_token=myaccesstoken'

in PHP? And how can I get the access token of users?

回答1:

To get the user access token in PHP SDK 3.1.1:

// Get the current access token
$access_token = $facebook->getAccessToken();
