Laravel 5.2-会话:::无法正常工作

Question

I want to display an 'falsh-message' for the user I start to redirect him in the routes.php with following code :

Route::get('/alert',function () {
    return redirect()->route('home')->with('message', 'This is a Test Message!');
});

In the alerts.blade.php that I include in the home view I would like to read this message with:

Route::group(['middleware' => ['web']], function () {
  Route::get('/alert',function () {
        return redirect()->route('home')->with('message', 'This is a Test Message!');
    });
});

My Session would be set under storage\\framework\\sessions with the following code :

a:5:{s:6:"_token";s:40:"8304u3fjR9EhvA88QMVGQnGcgdUcWoZj9LrHaDPh";s:7:"message";s:23:"This is a Test Message!";s:5:"flash";a:2:{s:3:"new";a:0:{}s:3:"old";a:1:{i:0;s:7:"message";}}s:9:"_previous";a:1:{s:3:"url";s:22:"http://localhost/alert";}s:9:"_sf2_meta";a:3:{s:1:"u";i:1452937821;s:1:"c";i:1452937821;s:1:"l";s:1:"0";}}

But the Problem is that Laravel gives me no output from the message because it is empty. So maybe someone can help me.

routes.php :

Route::group(['middleware' => ['web']], function () {
    Route::get('/', [
        'uses' => '\App\Http\Controllers\HomeController@index',
        'as' => 'home',
    ]);
    Route::get('/alert',function () {
        return redirect()->route('home')->with('message', 'This is a Test Message!');
    });
});

Answer 1

The web middleware group contains all the middleware required for sessions. Your alert route is in the middleware group, so it sets the session properly, however your home route needs to also be in the web middleware group to be able to read the session.

Answer 2

您可能应该将您的home路由放入您的route.php文件中的web中间件中，以使其工作

Answer 3

Insert session flash data explicitly..

Route::get('/alert',function () {
    $request->session()->flash('message', 'Task was successful!');
    return redirect()->route('home');
});

Answer 4

if you write like this :

Route::get('/alert',function () {
    return redirect()->route('home')->with('message', 'This is a Test Message!');
});

you will find a variable in view named $message; try and check echo $message;

It is one time use; you can also write:

Route::get('/alert',function () {
    $request->session()->flash('message', 'This is a Test Message!');
    return redirect()->route('home');
});

It is also one time use but you need to enable the session. If you want the message in session permanently yo can write:

Route::get('/alert',function () {
    $request->session()->put('message', 'This is a Test Message!');
    return redirect()->route('home');
});

Hope this will helps other to understand more clearly.
