Laravel Socialite Facebook Login Error: The parameter app_id is required

问题

Trying to get socialite to work on my app. Facebook returns the The parameter app_id is required error.

Routes:

Route::get('/login/facebook', '\CommendMe\Http\Controllers\AuthController@redirectToProvider');

Route::get('/login/facebook/callback', '\CommendMe\Http\Controllers\AuthController@handleProviderCallback');

services.php:

'facebook' => [
    'client_id' => env('426129694395672'),  
    'client_secret' => env('840fca14fc9fac4b592cd49f285c2ee9'), 
    'redirect' => 'http://localhost/login/facebook/callback',
],

AuthController.php

public function redirectToProvider() {
    return Socialite::driver('facebook')->redirect();
}   

public function handleProviderCallback() {
    $user = Socialite::driver('facebook')->user();

    $user->name;
}

When trying the /login/facebook route, facebook returns this error. Why is this happening?

回答1:

Either use as

'client_id' => '426129694395672',

'client_id' => env("FB_APP",'426129694395672'),

and use FB_APP = '426129694395672' in .env file

Instead

'client_id' => env('426129694395672'),

Using env('VarName') is to get value of environment variable named as VarName in .env file

回答2:

Assuming that you have the following in your .env file:

CLIENT_ID=426129694395672
CLIENT_SECRET=840fca14fc9fac4b592cd49f285c2ee9

The facebook[] in your services.php should be like this:

'facebook' => [
    'client_id' => env('CLIENT_ID'),  
    'client_secret' => env('CLIENT_SECRET'), 
    'redirect' => 'http://localhost/login/facebook/callback',
],
