方法Illuminate \ Auth \ RequestGuard :: attempt不存在

问题描述

我对Laravel和Lumen都是陌生的.我在lumen 5.6中使用oauth2.0创建了一个登录api，我已经安装了通行证并生成了令牌.以下是我的登录控制器功能，可以正常工作.它返回令牌.

I am new to both laravel and lumen.I was creating a login api with oauth2.0 in lumen 5.6, i have installed passport and generated token.Below is my login controller function and it is working fine. It returns token.

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Route;
//use Illuminate\Support\Facades\DB;
use App\User;
use Auth;

public function login(Request $request)
        {
            global $app;
            $proxy = Request::create(
                '/oauth/token',
                'post',
                [
                    'grant_type'    =>  env('API_GRAND_TYPE'),
                    'client_id'     =>  env('API_CLIENT_ID'),
                    'client_secret' =>  env('API_CLIENT_SECRET'),
                    'username'      =>  $request->username,
                    'password'      =>  $request->password,
                ]

            );
            return $app->dispatch($proxy);
        }

由于除了用户名和密码外，我还必须检查用户状态，因此我需要首先检查用户凭据.所以我确实喜欢这个.

Since i have to check user status apart from username and password, i need to check the user credential first. so i do like this.

public function login(Request $request)
{

    $credentials = $request->only('username', 'password');

    if (Auth::attempt($credentials)) {
        return ['result' => 'ok'];
    }

    return ['result' => 'not ok'];
}

Here i am getting this error.
Method Illuminate\Auth\RequestGuard::attempt does not exist.

So i tried Auth::check instead of Auth::attempt.
Now there is no error but it always return false even though the credentials are valid.

I searched a lot for a solution but i didn't get.

推荐答案

功能防护仅适用于具有Web中间件的路由

The function guard is only available for routes with web middleware

public function login() {

  if(Auth::guard('web')->attempt(['email' => $email, 'password' => $password], false, false)) {requests
     // good
  } else {
    // invalid credentials, act accordingly
 }
}
