laravel自定义多用户登录方法

• 最终路由是这样的（尤其注意后面的middleware）

Route::get('/', 'IndexController@index');
                Route::get('login', 'IndexController@loginForm');
                Route::post('login', 'IndexController@login');
                Route::get('logout', 'IndexController@logout');
                //产品分类auth:cpadmin
                Route::middleware('auth:cpadmin')->group(function(){
                    Route::resource('categories', 'CategoryController', ['parameters' => ['categories' => 'goods_category']]);
                    //产品
                });

• 创建模型及数据表（注意修改继承和trait，默认是继承自Model没有trait）

• 创建路由（将默认的Route::auth() 删除）

//登录表单
Route::get('/admin/login', 'xc\admin\LoginController@showLoginForm');
//登录提交
Route::post('/admin/login', 'xc\admin\LoginController@login');
//方便调试，退出登录使用了get
Route::get('/admin/logout','xc\admin\LoginController@logout');
//需要登录后能查看的页面
Route::get('/admin','xc\admin\IndexController@index');

• 增加guard及provider (文件位置：config/auth.php)

'guards' => [
        'web' => [
            'driver'   => 'session' ,
            'provider' => 'users' ,
        ] ,

        'api' => [
            'driver'   => 'token' ,
            'provider' => 'users' ,
        ] ,
        //新增
        'xcadmin' => [
            'driver'   => 'session' ,
            'provider' => 'members' ,
        ],
    ] ,
...
'providers' => [
        'users' => [
            'driver' => 'eloquent' ,
            'model'  => App\User::class ,
        ] ,
        //新增
        'members' => [
            'driver' => 'eloquent' ,
            'model'  => App\Member::class ,//对应得模型（数据表）
        ] 
    ] ,

• 修改重定向文件

• 修改异常文件（防止在未通过验证的情况向访问需要登录的页面，由于未登录而跳转到默认的/login）

• 登录控制器

namespace App\Http\Controllers\xc\admin;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
    use AuthenticatesUsers;

    protected function guard()
    {
        return Auth::guard('xcadmin');
    }

    public function showLoginForm()
    {
        dump(Auth::guard('xcadmin')->user());
        return view('xc.admin.login.login');
    }

    public function login(Request $request)
    {
        echo 'login';
        //此处如果使用默认的加密等方法的话这个login可以不用写，但是如果是改造旧系统使用md5、salt等加密的话，需要重写此方法，这里直接使用id登录省略等路方法
        \Illuminate\Support\Facades\Auth::guard('xcadmin')->loginUsingId(1 , true);
        //这是原始方法，参考
        /*$this->validate($request , [
            'email'    => 'required|email' ,
            'password' => 'required|min:6'
        ]);

        if( Auth::guard('admin')->attempt(['email' => $request->email , 'password' => $request->password] , $request->get('remember')) ) {

            return redirect()->intended('/admin');
        }
        return back()->withInput($request->only('email' , 'remember'));*/
        
        return redirect()->intended('/admin');
    }
    //重写下，否则退出后会跳转到/login
    public function logout(Request $request)
    {
        $this->guard()->logout();

        $request->session()->invalidate();

        return redirect('/admin/login');
    }

    protected $redirectTo = '/admin/';

    public function __construct()
    {
        //由于没有命名路由，这里是有点问题，目的是不让未登录用户访问这里
        $this->middleware('guest')->except('/admin/logout');
    }

    public function username()
    {
        //自定义的用户名，重写
        return 'mobile';
    }
}

• 需要登录后才能查看的页面

namespace App\Http\Controllers\xc\admin;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class IndexController extends Controller
{
    protected $redirectTo = '/admin/';
    public function __construct()
    {
        //重要，一定要这样写否则出错
        $this->middleware('auth:xcadmin');
    }
    public function index()
    {
        return 'admin/index';
    }
}

据此可以实现多用户登录
