Laravel Socialite Facebook错误：“POST https://graph.facebook.com/oauth/access_token导致'400 Bad Request`”

Question

I've made social login using Laravel Socialite for facebook and it was working fine. I haaven't changed anything and now it's not working. It shows this error when trying to login:

Client error: POST https://graph.facebook.com/oauth/access_token resulted in a 400 Bad Request response: {"error":{"message":"This IP can't make requests for that application.","type":"OAuthException","code":5,"fbtrace_id":"D (truncated...)

I haven't changed setting in my facebook app, nor in my code. My code is the following:

 Route::get('login', ['as' =>'getLogin', 'uses'=>'Auth\\AuthController@getLogin']); Route::get('handleProviderCallback/{provider}', 'Auth\\AuthController@handleProviderCallback'); 

 public function login($provider = false) { if(!$provider) { $user = Input::all(); $auth_user = new AuthenticateUser(); $is_logged = $auth_user->findByEmailOrCreate($user, false); if($is_logged) { Session::put('user', Auth::user()); Session::put('user_id', Auth::user()->id); Session::put('email', Auth::user()->email); Session::put('name', Auth::user()->name); return redirect()->intended('dashboard'); } return redirect('/')->withInput()->with('error', 'Wrong username or password!'); } return \\Socialite::with('facebook')->redirect(); } public function handleProviderCallback($provider=false) { if(Input::has('code')) { $user = \\Socialite::with($provider)->user(); $auth_user = new AuthenticateUser(); $provider_user = $auth_user->findByEmailOrCreate($user, $provider); Session::put("user", array($provider_user)); Session::put('user_id', $provider_user->id); Session::put('email',$provider_user->email); Session::put('name',$provider_user->name); return redirect('dashboard'); } } 

Problem appears in handleProviderCallback method in this line:

$user = \\Socialite::with($provider)->user(); .

When I only dump this: $user = \\Socialite::with($provider)

it shows data but when it is used like that to get user data it returns the error:

$user = \\Socialite::with($provider)->user();

In config/services.php I've set settings like this example:

  'facebook' => [ 'client_id' => 'my-client-id-from-fb-app', 'client_secret' => 'my-secret-code-from-fb-app', 'redirect' => 'http://my-example-domain/my-site/handleProviderCallback/facebook' ], 

In my facebook app I've set in settings:

App Domains: my-example-domain, Privacy Policy URL: http://my-example-domain/my-site/, Site URL: http://my-example-domain/my-site/handleProviderCallback/facebook, Valid OAuth redirect URIs: http://my-example-domain/my-site/handleProviderCallback/facebook

Answer 1

I had this message on my local machine after getting secret key value from .env file

ClientException in RequestException.php line 111:
enter code here Client error: `POST 
https://graph.facebook.com/v2.8/oauth/access_token` resulted in a `400 
Bad Request` response:
{"error":{"message":"Error validating client 
secret.","type":"OAuthException","code":1,"fbtrace_id":"ID"}}

As expected problem was with secret key, I pasted it wrong, so after double check and right copy/past from fb everything worked.

Hope this info will help somebody.

Answer 2

Yeah, I didn't check the request at all to see what's returned but someone on Larachat helped me solve this problem.

All I had to do before getting the user and handle the request was to add the following code in the callback method:

if (!$request->has('code') || $request->has('denied')) {
   return redirect('/');}

What's your Laravel version?

I've experienced the exact same problem and after going through the socialite package and make little changes, it solves the problem. You might want to give it a try.

vendor/laravel/socialite/TwoFacebookProvider line 81

Replace this

parse_str($response->getBody(), $data);

with

$data = json_decode($response->getBody(), true);

It seems like the data isn't adding
