Socialite 不能在 Laravel 中间件中工作，我该如何解决这个问题？

Question

我正在使用 Socialite 进行 Google 身份验证，我有一个中间件用于检查用户是否通过他们的 google_id 存在于我的本地数据库中，它可以重定向到 /home 页面，否则它将重定向回 Google身份验证页面，在执行此操作时，我遇到了中间问题，错误是：

客户端错误：POST https://www.googleapis.com/oauth2/v4/token 导致 400 Bad Request 响应：{ "error": "invalid_request", "error_description": "Missing required parameter: code" }

中间件

<?php

namespace App\Http\Middleware;
//use Socialite;
use App\GmailAccount;
use Closure;

use Laravel\Socialite\Facades\Socialite;

use Illuminate\Support\Facades\Auth;

class GoogleAuth
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

        $user = Socialite::driver('google')->stateless()->user();

        $finduser = GmailAccount::where('google_id', $user->id)->first();

        if($finduser){
            return $next($request);
        }

        else{
            return route('/logingoogle');
        }

    }
}

Route::group(['middleware' => 'App\Http\Middleware\GoogleAuth'], function()

    Route::get('/home', 'HomeController@index')->name('home');

});

Route::get('/logingoogle', 'GoogleController@google_login');

Answer 1

以下是一个工作示例：

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Socialite;
use App\User;

class LoginController extends Controller
{
    use AuthenticatesUsers;

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

    public function handleProviderCallback()
    {
        try {
            $user = Socialite::driver('google')->user();
        } catch (\Exception $e) {
            return redirect('/login');
        }

        // check if they're an existing user
        $existingUser = User::where('email', $user->email)->first();

        if ($existingUser) {
            // log them in
            auth()->login($existingUser, true);
        } else {
            // create a new user
            $newUser                  = new User;
            $newUser->name            = $user->name;
            $newUser->email           = $user->email;
            $newUser->google_id       = $user->id;
            $newUser->avatar          = $user->avatar;
            $newUser->avatar_original = $user->avatar_original;
            $newUser->lastlogin_at    = \Carbon\Carbon::now();
            $newUser->save();
            auth()->login($newUser, true);
        }
        session(['user_name' => $user->name]);
        session(['user_email' => $user->email]);
        session(['user_avatar' => $user->avatar]);

        return redirect()->to('/home');
    }
}

Route::get('/redirect', 'Auth\LoginController@redirectToProvider');
Route::get('/callback', 'Auth\LoginController@handleProviderCallback');

Answer 2

并包括这些：

use Illuminate\Foundation\Auth\AuthenticatesUsers; use Socialite;

Answer 3

你可以试试这个吗？

if($finduser) {
    auth()->login($finduser), true);
}
else {
    return redirect('/logingoogle');
}
