Lumen: print custom config return NULL

问题

I placed the configuration directory in the application root:

/config/app.php

Contents of /config/app.php:

<?php

return [
    'test' => 'this config should work',
];

In the /bootstrap/app.php:

$app->configure('app');

To test:

dd(config('app.test'));

Result is NULL :(. How can I fix it? I see that there is the same issue on github (https://github.com/laravel/lumen-framework/issues/107) but I have already updated my Lumen at the last version.

回答1:

I added following lines just before return $app; (this includes all files placed in config directory.

/*
|--------------------------------------------------------------------------
| Include all configs (by SK)
|--------------------------------------------------------------------------
|
| Here we include all php files that exists in config directory
|
*/
$files = scandir("config/");
if($files) {
    foreach($files as $file) {
        if(preg_match("@(\.php)$@",$file)) {
            // include app configs
            $app->configure($file);
        }
    }
}

回答2:

In your bootstrap.php file insert this

collect(scandir(__DIR__ . '/../config'))->each(function ($item) use 
($app) {
        $app->configure(basename($item, '.php'));
});
