My thoughts:

I wrote a tool class myself. Since it will be used in multiple places in the project, and I don’t want to instantiate it every time I use it, I want to register this tool in Laravel’s Service Container. But unfortunately there are some problems. I will paste the code and my own ideas directly below. Please tell me where the problem is? ? ? Thank you so much! ! !

Step one: Register the container first

<code>php artisan make:provider QcloudVideoServiceProvider</code>

Copy after login

The code is as follows:

<code><?php

namespace App\Providers;

use App\Xiaoteng\QCVod;
use Illuminate\Support\ServiceProvider;

class QcloudVideoServiceProvider extends ServiceProvider
{

    /**
     * Indicates if loading of the provider is deferred.
     *
     * @var bool
     */
    protected $defer = true;

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton('qcloud.vod', function ($app) {
            $glass = new QCVod(config('QCLOUD_KEY'), config('QCLOUD_SECRET'));
            return $glass->setRegion('gz');
        });
    }

    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides()
    {
        return ['qcloud.vod'];
    }
}
</code>

Copy after login

Step 2: Register for Facades

Create Foundation/Facades/QcloudFacades.php under the app directory, the code is as follows:

<code><?php
namespace App\Foundation\Facades;

use Illuminate\Support\Facades\Facade;

class QCvodFacades extends Facade
{

    /**
     * Get the registered name of the component.
     *
     * @return string
     */
    protected static function getFacadeAccessor()
    {
        return 'qcloud.vod';
    }

}</code>

Copy after login

Step 3: Register Service

<code>providers => [
    //...
    App\Providers\QcloudVideoServiceProvider::class,
]

aliases => [
    //...
    'QCvod' => App\Foundation\Facades\QCvodFacades::class,
]</code>

Copy after login

Step 4: Call

<code>dd(ACvod::getRegion());</code>

Copy after login

getRegion() is a getter method in the tool class

The question arises:

<code>Class qcloud.vod does not exist</code>

Copy after login

            $glass = new QCVod(config('QCLOUD_KEY'), config('QCLOUD_SECRET'));
            return $glass->setRegion('gz');
        });
    }

    /**

    public function provides()
    {
        return ['qcloud.vod'];
    }
}

use Illuminate\Support\Facades\Facade;

class QCvodFacades extends Facade
{

    /**

     *
     * @return string
     */
    protected static function getFacadeAccessor()
    {
        return 'qcloud.vod';
    }

}</code>

Copy after login

Step 3: Register Service

<code>providers => [
    //...
    App\Providers\QcloudVideoServiceProvider::class,
]

aliases => [
    //...
    'QCvod' => App\Foundation\Facades\QCvodFacades::class,
]</code>

Step 4: Call

<code>Class qcloud.vod does not exist</code>

Copy after login

QcloudVideoServiceProvider at

<code>$this->app->singleton('qcloud.vod', function ($app) {
   return new QCVod(config('QCLOUD_KEY'), config('QCLOUD_SECRET'));
});</code>

Copy after login

That should be it.

I haven’t written “service provider” and “facade” yet. I feel like singleton()should write the full namespace here.

If it is only used as a tool class, please refer to laravel auxiliary function

composer dump-autoload
