php - Laravel 身份验证 - 即使凭据正确且与数据库完全相同，用户也无法登录

Question

我正在创建一个新项目，在创建系统身份验证所需的所有模块后，我无法登录并转到正确的页面，即使登录凭据正确且与数据库。这是代码。请帮助我确切地知道我哪里出错了，提前谢谢你。

控制器

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Validator;
use Auth;

class AuthController extends Controller
{
    function index() {
        return view('auth/login');
    }

    function checklogin(Request $request) {
        $this->validate($request, [
            'username'=>'required|email',
            'password'=>'required|min:6'
        ]);

        $user_data = array(
            'username'=>$request->get('username'),
            'password'=>$request->get('password')
        );

        if(Auth::attempt($user_data)) {
            return redirect('personnel');
        }else {
            return back()->with('error', 'Wrong Login Details');
        }
    }

    function successlogin() {
        return view('personnel');
    }

    function logout() {
        Auth::logout();
        return redirect('auth');
    }
}

web.php - 这是路线

Auth::routes();

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

登录

Route::get('/auth', 'AuthController@index');
Route::post('/auth/checklogin', 'AuthController@checklogin');
Route::get('/auth/logout', 'AuthController@logout');

人员

Route::get('/personnel', function () {
    return view('personnel');
});

Answer 1

因为您使用的是username列而不是 laravel 的默认email列，

尝试这样做：

if(Auth::attempt(['username' => $request['username'], 'password' => $request['password']])) {
   return redirect('personnel');
}else {
    return back()->with('error', 'Wrong Login Details');
}
