Laravel 5更改环境以匹配URL

Question

I have installed a fresh copy of Laravel.

I need it so i can set the environment to the URL.

So for instance in L4 i used this within the start.php file

$env = $app->detectEnvironment(function()
{
    return isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : '';
});

This then loaded the correct environment for the project, so if we had a local domain dev.laravel.com it would load in the environment variables from dev.laravel.com

I cannot do this within Laravel 5.

Any guesses how I can apply this?

You can for example do it for use different database, then you have some different variables on .env like:

DB_HOST=localhost
DB_DATABASE=database1
DB_USERNAME=foo
DB_PASSWORD=foo

DB_HOST_2=localhost
DB_DATABASE_2=database2
DB_USERNAME_2=foo
DB_PASSWORD_2=foo

and in config/dababase.php:

'connections' => [

        'mysql' => [
            'driver'    => 'mysql',
            'host'      => env('DB_HOST', 'localhost'),
            'database'  => env('DB_DATABASE', 'forge'),
            'username'  => env('DB_USERNAME', 'forge'),
            'password'  => env('DB_PASSWORD', ''),
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ],

        'mysql2' => [
            'driver'    => 'mysql',
            'host'      => env('DB_HOST_2', 'localhost'),
            'database'  => env('DB_DATABASE_2', 'forge'),
            'username'  => env('DB_USERNAME_2', 'forge'),
            'password'  => env('DB_PASSWORD_2', ''),
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ],

and finally use:

Config::set('database.default', "mysql") or Config::set('database.default', "mysql2")

depending you need.

For example I use to change database connection after login user doing it at controller abstract class changing the value depending session var, that is changed after login depending type of user:

abstract class Controller extends BaseController {

    use DispatchesCommands, ValidatesRequests;

    public function __construct()
    {
        Config::set('database.default', Session::get('myapp.database','mysql'));
    }
}

After login I put to change this value:

Session::set('myapp.database', 'mysql2') or Session::set('myapp.database', 'mysql')

and in the next call to controller the database connections is changed.
