Problem with Facebook Open Graph API call... need an active access token?
I'm using Facebook's open graph api along with the JavaScript SDK on my site. My goal is for a user to connect to my site and then after performing certain actions on my site publish a message to the users facebook stream. I have the facebook connect function working just fine. During the connect I request email, publish_stream, offline_access permissions. I think those are all I need for what I'm trying to do. Now when the user connects via facebook connect I do get and capture the facebook access token and secret though I don't know what to do with them.
According to Facebook's shoddy documentation for the JavaScript SDK... to do what I'm trying to do it says to use the following code:
var body = 'Reading Connect JS documentation';
FB.api('/me/feed', 'post', { message: body }, function(response) {
if (!response || response.error) {
alert('Error occured');
} else {
alert('Post ID: ' + response.id);
}
});
I'm doing just that as a test and instead of alerting the response I'm stringifying the JSON response and writing to the console. Suffice it to say the stream publish fails and the response is this:
{"error":{"type":"OAuthException","message":"An active access token must be used to query information about the current user."}}
If the user is 'connected' to my site via facebook connect and accepted all the permi开发者_开发问答ssions I specified, don't I have a valid access token? Is the access token another parameter I have to pass to the api call?
Make sure you have all this in the page:
<BODY>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script type="text/javascript">
FB.init({
appId : APP_ID, // the app ID you get when you register your app in http://www.facebook.com/developers/
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
if (FB.getSession() != null) {
var body = 'Reading Connect JS documentation';
FB.api('/me/feed', 'post', { message: body }, function(response) {
if (!response || response.error) {
alert('Error occured');
} else {
alert('Post ID: ' + response.id);
}
});
}
</script>
The above code worked for me with the publish_stream permission. Make sure that the code is not running before the javascript api has received the access token. Run:
console.log(FB.getSession())
directly above the FB.api call to make sure you have an access_token.
