facebook-authentication

问题 UPDATE 2: OK, got it "kind of" working by changing: $loginUrl = $facebook->getLoginUrl(array( 'canvas' => 1, 'fbconnect' => 0, 'req_perms' => 'publish_stream', 'next' => 'http://'.$_SERVER['SERVER_NAME'].'/success.php', 'cancel_url' => 'http://'.$_SERVER['SERVER_NAME'].'/cancel.php' )); to this: $loginUrl = $facebook->getLoginUrl(array( 'canvas' => 1, 'fbconnect' => 0, 'req_perms' => 'publish_stream', 'next' => 'http://'.$_SERVER['SERVER_NAME'].'/success.php', 'cancel_url' => 'http://'.$

问题 I'm developing mobile first app, using Firebase Auth. Firebase recommends redirect instead of popup. However, I can't seem to find any example of retrieving errors on using Oauth providers (facebook ,Google). Firebase has an example of handling error in SignwithPopup , but fore redirect it only states: This error is handled in a similar way in the redirect mode, with the difference that the pending credential has to be cached between page redirects (for example, using session storage). 回答1:

问题 I'm trying to move to my new view controller after the auth is complete and the user has loged into facebook but I get a error saying "Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information."" I've looked over the documentation and it looks right to me but maybe I'm missing something. Here is my code for my facebook login button @IBAction func FacebookBtnPressed(sender: AnyObject) { let login = FBSDKLoginManager()

问题 I'm writing a Facebook app that lists the user's friends, cross-referenced with information the user has provided about them (which is stored in a Google App Engine database). Here is how my app operates: After the user logs into Facebook, a Graph API call is made through Facebook's Javascript SDK to obtain a list of their friends. Simultaneously, an AJAX request is sent out to my Google App Engine request handler with the user's Facebook ID, and the handler sends back a JSON object with

问题 Sometimes (not very frequently) my android app crashes after first logging to facebook using Facebook Login (Facebook SDK version 3.5). I'm getting exception: java.lang.RuntimeException: Unable to resume activity {my.app.package/com.facebook.LoginActivity}: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=64206, result=0, data=null} to activity {my.app.package/com.facebook.LoginActivity}: java.lang.NullPointerException with 2 different root exceptions:

问题 I have an facebook login system which works with firebase but I want to check if user exist on my firebase (i don't want to add it, just want to make sure if he exist because I want to redirect user to another page to complete its profile, once its done I'll want to send it to firebase). I just need to check if user exist on my db. Here is the code that I try but it returns nil error and it automatically add user to firebase. let credential = FIRFacebookAuthProvider.credentialWithAccessToken

问题 We redirect users to below URL on mobile phones for application authorisation: https://m.facebook.com/dialog/oauth?client_id=XXXXXX&redirect_uri=http://www.server.com/callback.php&scope=offline_access,user_likes,publish_stream,publish_checkins,user_checkins&display=wap If the user is logged in to Facebook on his/her phone, no problem, Facebook automatically redirects to oauth dialog page. If user is not logged in, Facebook asks them to login first. On wap site(A Nokia phone), it redirects to

问题 Trying to register app gave me: Error App Domain: http://www.universalfather.info is not a valid domain. But it IS a valid domain. Is this because it is a ".info" website? 回答1: Add "universalfather.info" as domain and http://www.universalfather.info as siteURL. 回答2: I believe Alex's answer is correct, but you may also have a problem because your base domain (without the www) isn't resolving an A record: host universalfather.info universalfather.info mail is handled by 10 mx1.webhero.com.

问题 My friend called this like lambda-calculus, even though I know some lambas -- I am still confused how the authorization really works to get the access token. So please explain this code, hopefully line-by-line. Source of the example is here. FB.login(function(response) { if (response.authResponse) { console.log('Welcome! Fetching your information.... '); FB.api('/me', function(response) { console.log('Good to see you, ' + response.name + '.'); }); } else { console.log('User cancelled login or

问题 Alright, so for a couple days now I have been trying to integrate Facebook authentication into my Codeigniter based website. I have included the Facebook PHP SDK as a library and that seems to connect just fine, however when I use the getUser method in the SDK a 0 is returned indicating that I am not logged in (except that I am logged in to facebook). Below I have included the PHP SDK in library form, the model that calls the methods in the SDK, the controller that captures data from the
