API Key Error in Facebook Connect (javascript sdk)
I am trying to implement Facebook Connect on a website. I am trying to work with Javascript SDK of Facebok. I am new to it and unfortunately most of links provided in Facebook WIKI are out of date... Returning 404 not found. Anyway I added this code before the ending </body>:
<script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"></script>
<div id="fb-root"></div>
<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"> </script>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({
appId : '12344', // my real app id is here
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : false // parse XFBML
});
FB.login(function(response) {
if (response.session) {
if (response.perms) {
alert('user is logged in and granted some permissions');
// user is logged in and granted some permissions.
// perms is a comma separated list of granted permissions
} else {
alert('user is logged in, but did not grant any permissions');
开发者_C百科 // user is logged in, but did not grant any permissions
}
} else {
alert('user is not logged in');
// user is not logged in
}
}, {perms:'email'});
</script>
And I have a login button at some other place (much before the above scripts) in the same page rendered with:
<fb:login-button v="2">Connect with Facebook</fb:login-button>
This button renders as a normal fb connect button and clicking it opens a new popup window as it normally should. Problem is that it shows 'invalid api key specified' error. On inspecting address bar of popup, I see that api_key=undefined is passed to it :(
Any idea about this? I am trying to fix this for last 5 hours now... Please help me found out why correct API key is not being passed to popup window.
Thanks in advance.
I'm doing the same thing, and i found an example that is very simple to implement and understand (here thay use jQuery, but you can do the same without libraries):
<body>
<div>
<button id="login">Login</button>
<button id="disconnect">Disconnect</button>
</div>
<div id="user-info" style="display: none;"></div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
// initialize the library with the API key
FB.init({ appId : '12344' });
// fetch the status on load
FB.getLoginStatus(handleSessionResponse);
$('#login').bind('click', function() {
FB.login(handleSessionResponse);
});
$('#disconnect').bind('click', function() {
FB.api({ method: 'Auth.revokeAuthorization' }, function(response) {
clearDisplay();
});
});
// no user, clear display
function clearDisplay() {
$('#user-info').hide('fast');
}
// handle a session response from any of the auth related calls
function handleSessionResponse(response) {
// if we dont have a session, just hide the user info
if (!response.session) {
clearDisplay();
return;
}
// if we have a session, query for the user's profile picture and name
FB.api(
{
method: 'fql.query',
query: 'SELECT name, pic FROM profile WHERE id=' + FB.getSession().uid
},
function(response) {
var user = response[0];
$('#user-info').html('<img src="' + user.pic + '">' + user.name).show('fast');
}
);
}
</script>
</body>
Look here for the entire code, and here you can find other resource.
I had set my facebook connect address to have www and I was accessing my test site with non www, when I switched to the www version fb connect worked fine.
You need to set the canvas post-authorize url, and make sure that the base canvas url is a prefix of the post-authorize url.
