在工厂类Laravel 5.4之前实现Facade [英] Implementation of Facade in front of Factory class Laravel 5.4
问题描述
对于某些情况-今天早些时候，我正在努力弄清楚如何实现类似于Cache的外观-在这里我可以设置提供程序(如disk())，但在不提供时也具有通用的后备提供程序. /p>
现在，我已使基本基础结构正常工作，但是我认为我的实现令人讨厌.调用default()或provider()只是发臭.但是，有一个概念或我缺少的东西可以填补这里的空白.
对Cache实现类似的功能:: Laravel中的磁盘('x')
这就是我所做的.
// Factories\SMSFactory.php
namespace App\Factories;
use App\IError;
class SMSFactory
{
public static function default()
{
$defaultProvider = config('sms.default_provider');
return self::provider($defaultProvider);
}
public static function provider($providerId)
{
$providerClass = config('sms.' . $providerId);
if (class_exists($providerClass))
{
return (new $providerClass);
}
return new class implements IError {
};
}
}
// sms.php (config)
return [
/**
* Set the default SMS provider for the application
*/
'default_provider' => 'smsglobal',
/**
* Map the SMS provider to a class implementation
*/
'smsglobal' => 'App\SMSGlobal\SMSGlobal',
];
// Providers\SMSServiceProvider.php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class SMSServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
*
* @return void
*/
public function register()
{
$this->app->bind('sms', 'App\Factories\SMSFactory');
}
}
// Facades\SMS.php
namespace App\Facades;
use Illuminate\Support\Facades\Facade;
class SMS extends Facade
{
protected static function getFacadeAccessor()
{
return 'sms';
}
}
// app.php
App\Providers\SMSServiceProvider::class,
# and in aliases
'SMS' => App\Facades\SMS::class,
// Controllers/TestController.php
namespace App\Http\Controllers\TestController;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Facades\SMS;
class TestController extends Controller
{
public function sendSMS($destination, $message)
{
$data = $request->all();
return SMS::default()->send([
'destination' => $destination,
'message' => $message,
]);
}
}
真正困扰我的是必须始终使用default()...
我知道外观是一个静态类，但是是否可以以这种方式进行设置呢?
SMS::send($args);
// When I want to use another gateway
SMS::provider('nexmo')->send($args);
您可以在SMS Factory类中使用__call方法，并且必须相应地对其进行更改:
class SMSFactory
{
public function default()
{
$defaultProvider = config('sms.default_provider');
return $this->provider($defaultProvider);
}
public function provider($providerId)
{
$providerClass = config('sms.' . $providerId);
if (class_exists($providerClass))
{
return (new $providerClass);
}
return new class implements IError {
};
}
public function __call($name, $arguments)
{
if (!method_exists($this, $name)) {
$object = [$this->default(), $name];
} else {
$object = [$this, $name];
}
return call_user_func_array($object, $arguments);
}
}
SMSFactory类不应具有静态方法，因为可以通过外观访问静态方法.
For some context - earlier today I was struggling to figure out how to implement a facade similar to Cache - where I could set a provider (like disk()), but also have a generic fall back provider when not supplied.
Now, I got the basic infrastructure working, but I think my implementation is nasty. Having call default() or provider() just stinks. However, there is a concept or something I'm missing to fill in the gaps here.
Implementing similar functionality to Cache::disk('x') in Laravel
Here is what I've done.
// Factories\SMSFactory.php
namespace App\Factories;
use App\IError;
class SMSFactory
{
public static function default()
{
$defaultProvider = config('sms.default_provider');
return self::provider($defaultProvider);
}
public static function provider($providerId)
{
$providerClass = config('sms.' . $providerId);
if (class_exists($providerClass))
{
return (new $providerClass);
}
return new class implements IError {
};
}
}
// sms.php (config)
return [
/**
* Set the default SMS provider for the application
*/
'default_provider' => 'smsglobal',
/**
* Map the SMS provider to a class implementation
*/
'smsglobal' => 'App\SMSGlobal\SMSGlobal',
];
// Providers\SMSServiceProvider.php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class SMSServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
*
* @return void
*/
public function register()
{
$this->app->bind('sms', 'App\Factories\SMSFactory');
}
}
// Facades\SMS.php
namespace App\Facades;
use Illuminate\Support\Facades\Facade;
class SMS extends Facade
{
protected static function getFacadeAccessor()
{
return 'sms';
}
}
// app.php
App\Providers\SMSServiceProvider::class,
# and in aliases
'SMS' => App\Facades\SMS::class,
// Controllers/TestController.php
namespace App\Http\Controllers\TestController;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Facades\SMS;
class TestController extends Controller
{
public function sendSMS($destination, $message)
{
$data = $request->all();
return SMS::default()->send([
'destination' => $destination,
'message' => $message,
]);
}
}
What is really bothering me is having to always use default()...
I understand that the facade acts as a static class, but is it possible to set it up in such a way that I could make calls like this?
SMS::send($args);
// When I want to use another gateway
SMS::provider('nexmo')->send($args);
You can use the __call method in your SMS Factory class, and it must be changed accordingly:
class SMSFactory
{
public function default()
{
$defaultProvider = config('sms.default_provider');
return $this->provider($defaultProvider);
}
public function provider($providerId)
{
$providerClass = config('sms.' . $providerId);
if (class_exists($providerClass))
{
return (new $providerClass);
}
return new class implements IError {
};
}
public function __call($name, $arguments)
{
if (!method_exists($this, $name)) {
$object = [$this->default(), $name];
} else {
$object = [$this, $name];
}
return call_user_func_array($object, $arguments);
}
}
The SMSFactory class should not have static methods as the static methods can be accessed through facade.
