laravel 添加后台登陆守护器

后台不能在一个浏览器登陆，下面简单配置下即可解决这个问题。

设置路由如下：

<?php

/**
 * 后台路由，从Illuminate\Routing\Router控制器的auth()方法中复制过来的
 */
Route::namespace(\'Admin\')->group(function () {
    // Authentication Routes...
    Route::get(\'login\', \'Auth\LoginController@showLoginForm\')->name(\'admin.login\');
    Route::post(\'login\', \'Auth\LoginController@login\');
    Route::post(\'logout\', \'Auth\LoginController@logout\')->name(\'admin.logout\');

// Registration Routes...
    Route::get(\'register\', \'Auth\RegisterController@showRegistrationForm\')->name(\'admin.register\');
    Route::post(\'register\', \'Auth\RegisterController@register\');

// Password Reset Routes...
    Route::get(\'password/reset\', \'Auth\ForgotPasswordController@showLinkRequestForm\')->name(\'admin.password.request\');
    Route::post(\'password/email\', \'Auth\ForgotPasswordController@sendResetLinkEmail\')->name(\'admin.password.email\');
    Route::get(\'password/reset/{token}\', \'Auth\ResetPasswordController@showResetForm\')->name(\'admin.password.reset\');
    Route::post(\'password/reset\', \'Auth\ResetPasswordController@reset\');

    Route::middleware(["auth:admin"])->group(function () {
        Route::get(\'/\', \'AdminController@index\')->name(\'admin\');
    });
});

<?php

/**
 * 前台路由，从Illuminate\Routing\Router控制器的auth()方法中复制过来的
 */
Route::get(\'/\', function () {
    return view(\'welcome\');
});

// Authentication Routes...
Route::get(\'login\', \'Auth\LoginController@showLoginForm\')->name(\'login\');
Route::post(\'login\', \'Auth\LoginController@login\');
Route::post(\'logout\', \'Auth\LoginController@logout\')->name(\'logout\');

// Registration Routes...
Route::get(\'register\', \'Auth\RegisterController@showRegistrationForm\')->name(\'register\'
