Laravel 不会触发 ComposerServiceProvider 类

Question

我在 ComposerServiceProvider 文件的 boot 方法中放置的“view()->share(...)”不起作用。但是当我把它放在 AppServiceProvider 中时它可以工作。我还在 app.php 文件的“providers”部分添加了 ComposerServiceProvider。

错误：

ErrorException
Undefined variable: test (View: /Users/devtools/Projects/sites/laravel/resources/views/components/backend/sidebar/menu-list.blade.php)
http://localhost/tr/admin/settings

可能是什么问题？感谢您的帮助。

它们是我的代码：

namespace App\Providers;
use Illuminate\Support\ServiceProvider;

class ComposerServiceProvider extends ServiceProvider
{
    // ...

    public function boot()
    {
        // This code works when I put it in AppServiceProvider.php
        view()->composer('*', function ($view) {
            view()->share('test', 'deneme');
        });
    }
}

config/app.php：

// ...
'providers' => [
  /*
   * Application Service Providers...
   */
   App\Providers\ComposerServiceProvider::class,
],

routers/web.php：

Route::prefix(LaravelLocalization::setLocale() . "/admin")
    ->name('admin.')
    ->middleware(['localeSessionRedirect', 'localizationRedirect', 'localize', 'auth', 'verified'])
    ->group(function ()
    {
        Route::get('/', function () {
            return view('backend.home');
        })->name('home');
    });

如您所见，这些是文件名和路径

解决方案：

问题是我删除了“数据”文件夹 “存储/框架/缓存/”。当我运行“php artisan cache:clear” 命令，它给出了一个错误。我添加了文件夹，没关系。

试试这个：

    View::composer('*', function($view)
    {
        $view->share('test', 'deneme');
    });

别忘了添加这个：

use View;
