不同控制器动作的一种途径

Question

I want to use one route for one controller but different actions. I woud like to switch the action of controller by the current value in session, but don't change the route (current url in browser).

I tried this code:

$token = session('stravaAccessToken');
$athlete = session('stravaAthlete');
$stats = session('stravaStats');

if (empty($token) || empty($athlete) || empty($stats)) {
    Route::get('/', 'StravaController@login');
} else {
    Route::get('/', 'StravaController@index');
}

but, the session values returned always null (may be values are cached?!)

I woud like to use there code below, but there don't work as need... I have the session values as right as well, but, I don't understand, what do I need to return from callback function?

Route::get('/', function(){
    $token = session('stravaAccessToken');
    $athlete = session('stravaAthlete');
    $stats = session('stravaStats');

    if (empty($token) || empty($athlete) || empty($stats)) {
        Route::get('/', 'StravaController@login');
    } else {
        Route::get('/', 'StravaController@index');
    }
});

php 7.1, laravel 5.8

for first variant of code: always opened an action 'StravaController@login', for second variant of code: opened blank page

I woud like to expect an action 'StravaController@index' (is session values not empty) or an action 'StravaController@login' (if session values are empty)

Answer 1

Send everything to one function:

Route::get('/', 'StravaController@handle');

and have that function call the login / index functions accordingly:

public function handle() {
    $token = session('stravaAccessToken');
    $athlete = session('stravaAthlete');
    $stats = session('stravaStats');

    if (empty($token) || empty($athlete) || empty($stats)) {
        return $this->login();
    } else {
        return $this->index();
    }
}

An alternative option would be putting the login page on a different route, and having middleware redirect to it if the "logged in" data isn't present.
