Passport: `POST http://passport.dev/oauth/token` resulted in a `400 Bad Request` response:

i am following laracasts video to set up passport, but it's giving the exception on Guzzle request in callback

code :

Route::get('/', function () {
     $query = http_build_query([
        'client_id' => 1,
        'redirect_url' => 'http://consumer.dev/callback',
        'response_type' => 'code',
        'scope' => ''
      ]);

     return redirect('http://passport.dev/oauth/authorize?'.$query);
});

Route::get('/callback', function (Request $request) {
    $http = new GuzzleHttp\Client;

    $response = $http->post('http://passport.dev/oauth/token', [
        'form_params' => [
            'grant_type' => 'authorization_code',
            'client_id' => 1,
            'client_secret' => 'JzyOQCKcmVHt5wgjtS45iAz3rcPKbiCUnd0rNfOj',
            'redirect_uri' => 'http://consumer.dev/callback',
            'code' => $request->code,
        ],
    ]);

    return json_decode((string) $response->getBody(), true);
});

it seems the redirect_uri is null in $authCodePayload in file AuthCodeGrant.php line number 97 after decrypting the authcode value.

Not sure why this is, and it's probably caused by the PHP League OAuth2 package, but you must pass your client_id in as a string, as opposed to an integer.

string is passed for client_id param

the problem was fixed . the problem was due to differences in redirect_url in first and redirect_uri ... L vs I (eye) . Thank you @adamgoose

Create a variable in .env and changed value according your App URL instead localhost and use during post URL.

GUZZLE_POST_URL='localhost/oauth/token'

$user = Auth::user();
$http = new GuzzleHttp\Client;
//get from env file
$url = env('GUZZLE_POST_URL');
$response = $http->post($url, [
'form_params' => [
'grant_type' => 'password',
'client_id' => Config::get('constant_define.passport_api_password_grant_client_id'),
'client_secret' => Config::get('constant_define.passport_api_password_grant_client_secret'),
'username' => $email,
'password' => $password,
'scope' => '*',
],
]);
