我试图在Laravel中设置路由保护，但收到以下错误消息：

我做错了什么？错误来自哪里？昨天一切顺利

My

Route::post('/signin', [

希望您能帮助我。

我看不到任何可能引发此问题的路线。唯一的问题是，试图访问您的仪表板的非授权用户将被重定向到

/login

，这可能会导致此触发器。进行以下更改。您还缺少用于重定向已登录用户的来宾中间件

重定向试图访问身份验证页的未经身份验证的用户

app/Exceptions/Handler.php

return redirect()->guest(route('home'));

您需要重定向试图访问仅来宾页面的身份验证用户，所以将他们重定向到仪表板而不是主页

app/Http/Middleware/RedirectIfAuthenticated.php

return redirect()->route('dashboard');

将来宾中间件应用于非身份验证路由

<?php

Route::group(['middleware' => ['guest']], function () {

    Route::get('/', function () {
        return view('welcome');
    })->name('home');

    Route::post('signup', [
        'uses' => 'UserController@postSignUp',
        'as' => 'signup'
    ]);

    Route::post('signin', [
        'uses' => 'UserController@postSignIn',
        'as' => 'signin'
    ]);
});


Route::get('dashboard', [
    'uses' => 'UserController@getDashboard',

不起作用。。单击“提交”按钮后，我得到：对不起，找不到您要查找的页面，上面出现了相同的错误。@Codehan25提交什么？注册还是登录？同时运行
php artisan route:list
并将结果发布到您的问题中……两者都可以，无论表单是否为空。我已经用php artisan route:list的结果更新了我的问题。@Codehan25从您的应用程序文件夹中运行
php artisan Service
，然后从访问站点并检查它是否有效。您不应该在xampp的目录路径下运行laravel应用程序，因为它需要重写url。不起作用。。单击“提交”按钮后，我得到：对不起，找不到您要查找的页面，上面出现了相同的错误。@Codehan25提交什么？注册还是登录？同时运行
