Laravel 5无法使用AppServiceProvider中的boot与视图共享数据

Question

Just done a fresh install of L5 and, as per the documentation, i'm trying to share data with all views using a simple share method in the AppServiceProvider class.

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use View;

class AppServiceProvider extends ServiceProvider {

/**
 * Bootstrap any application services.
 *
 * @return void
 */

public function boot()
{
    View::share('website', 'test');
}

/**
 * Register any application services.
 *
 * This service provider is a great spot to register your various container
 * bindings with the application. As you can see, we are registering our
 * "Registrar" implementation here. You can add your own bindings too!
 *
 * @return void
 */
public function register()
{
    $this->app->bind(
        'Illuminate\Contracts\Auth\Registrar',
        'App\Services\Registrar'
    );
}

}

route file:

Route::get('/', function(){
return view('test');
});

blade file:

<h1>Test</h1>
{{ $website }}

This should be really easy, so i'm wondering if i've made a very obvious mistake at the installation stage.

Thanks

Most probably you should clear the compiled.php file by running:

php artisan clear-compiled

or by manual deleting vendor/compiled.php (in previous L5 versions it's storage/framework/compiled.php).

Here's the explanation. Laravel pre-compiles certain classes that are used on basically every request. This serves the purpose of performance optimization. Files to compile can be specified in config/compile.php under files. The default one looks like this:

'files' => [
    realpath(__DIR__.'/../app/Providers/AppServiceProvider.php'),
    realpath(__DIR__.'/../app/Providers/BusServiceProvider.php'),
    realpath(__DIR__.'/../app/Providers/ConfigServiceProvider.php'),
    realpath(__DIR__.'/../app/Providers/EventServiceProvider.php'),
    realpath(__DIR__.'/../app/Providers/RouteServiceProvider.php'),
],

That means if you change one of those precompiled files, changes won't be applied immediately (if compiled.php exists) but only after you run php artisan optimize again or after you run php artisan clear-compiled to clear the compiled.php file.
