Why do we need to create a channel.html on our server to use Facebook JS SDK?

阅读更多关于 Why do we need to create a channel.html on our server to use Facebook JS SDK?

问题 I really don't understand why do we need to create channel.html file, as mentioned by FB docs. I also want to understand how it is used. In my logs I don't see this file being ever requested. 回答1: The channel file is to provide a way to do cross domain communication between FB's servers and your own. The reason for this is their tight control over access tokens. You must authenticate a redirect url and app id to retrieve this access token. In order for them to pass you the token, they hit

facebook like button not displaying :: FB.getLoginStatus() called before calling FB.init()

阅读更多关于 facebook like button not displaying :: FB.getLoginStatus() called before calling FB.init()

I just want a basic facebook like button on my site. I follow the instructions per facebooks site (http://developers.facebook.com/docs/reference/plugins/like/). I tried the HTML5 , XFBML , and iFrame ways, no joy on either. So I thought maybe it's something with my site interfering. So I created a bare-bones html page like below and it still gives me the FB.getLoginStatus() called before calling FB.init() error. <html> <body> <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id;

How to log out user from facebook application, but maintain login from facebook

阅读更多关于 How to log out user from facebook application, but maintain login from facebook

I have tried the PHP SDK (v.3.1.1), and the current Javascript SDK as suggested here : https://developers.facebook.com/docs/guides/web/ now when trying to log out I have tried both FB.logout() ( for js ) and $facebook->getLogoutUrl() ; as the documentation for both clearly state, these methods log the user out of the application as well as their facebook session. But I only need to log the user out of the facebook application ( the test site ). I have tried logging the user out of my test site, ignoring the facebook aspect. But in this case, when the user clicks the login button again, the

问题 I have problem in a script that was working until 3 or 4 days ago.

It continues to work normaly. I Know that I can force the parameter display: 'popup', but sending the request after some other javascript lines it means that

I am currently developing a web application with the Facebook Graph API. My current goal is to retrieve only posts which have a location attached. While retrieving posts with and without location is already working, I am not able to retrieve only posts with location. The query which retrieves both types looks like this: '/me/feed?fields=id,name,message,picture,place,with_tags&limit=100&with=location' The query which should retrieve only posts with location looks like this: /me/feed?fields=id,name,message,picture,place,with_tags&limit=100&with=location The problem I have is that with the

Is there a Facebook Share button event for FB.Event.subscribe?

阅读更多关于 Is there a Facebook Share button event for FB.Event.subscribe?

问题 I'm looking to split test clicks between the Facebook Like button and Facebook Share button. I know I can attach an event handler of FB.Event.subscribe('edge.create',...) to track clicks on the Facebook like button, but is there a corresponding event for the Facebook share button? There doesn't appear to be on in the FB.Event.subscribe documentation. 回答1: There is no event for this - if you need to be notified when a user clicks shares from within your app, you should create your own share

Facebook Login API HTTPS Issue

阅读更多关于 Facebook Login API HTTPS Issue

The website I'm working on has a Facebook login option, but recently a user reported it wasn't working for them. I disabled my extensions etc, I got this error in my console: Blocked a frame with origin "https://www.facebook.com" from accessing a frame with origin "http://static.ak.facebook.com". The frame requesting access has a protocol of "https", the frame being accessed has a protocol of "http". Protocols must match. Is there an option I can feed to the API that will get it to work on the same protocols? FYI, the primary website runs on HTTP (no S). It is especially odd because it seems
