在Laravel中实现与Cache :: disk('x')类似的功能 [英] Implementing similar functionality to Cache::disk('x') in Laravel

问题描述

这只是我要寻找的解决方案的一个普遍问题.

This is just a general question around a solution I'm trying to find.

我可能有许多提供相同类型服务的提供商，我需要一种能够拥有默认服务的方法，然后还需要手动调用切换器方法来更改它们.

I have potentially many providers of the same type of service and I need a way to be able to have a default, but then also manually call a switcher method to change them.

当前，我已经通过配置设置将接口绑定到实现，并且效果很好-但这意味着我只能为每种服务类型支持一个活动的提供程序.

Currently, I've bound an Interface to an Implementation via configuration settings and this works well - but it means I can only support one active provider per type of service.

我注意到Cache :: disk()方法确实是我想要的，但是我不确定应该在哪里定义这种类型的switch方法.

I noticed the Cache::disk() method is really what I'm looking for, but I'm not sure where this type of switch method should be defined.

当前:

interface IProvider {

    public function getServiceInfo($args);

    public function setServiceInfo($args);

}

class GoldService implements IProvider {
    // implementation of the two interface methods

}

class SilverService implements IProvider {

}


// ProviderServiceProvider

public function register()
{
    $this->app->bind(
        App/IProvider,
        App/GoldService
    );
}


// Controller

public function getServiceInfo(Service $serviceId) 
{
    $provider = $app->make('App/IProvider');
    $provider->getServiceInfo($serviceId);
}

想要.

// What I want to be able to do
public function getServiceInfo(Service $serviceId)
{
    // Using a facade

    if ($serviceId > 100)
    {
        Provider::getServiceInfo($serviceId);       
    }
    else 
    {
        Provider::switch('SilverService')
            ->getServiceInfo($serviceId);
    }
}

我知道我对Facade提出了附加要求-不确定我是否在这里混淆了Contracts/Fades-但本质上我希望接口强制执行实例方法，但是Facade可以方便地访问实例

I know I've thrown in an additional requirement there of the Facade - not sure if I've confused Contracts/Facades here - but essentially I want the interface to enforce the instance methods, but Facade for easy access to the instances.

并不是在这里真正寻找代码-这将很容易.我只是不确定我是否真的想过这个，并正在朝着正确的方向寻找微动.

Not really looking for code here - that'll be the easy part. I'm just not sure I've really grok'd this and looking for a nudge in the right direction..

推荐答案

使用接口确保服务实现您所需的方法是合理的.

Using an interface to ensure a service implements the methods you require makes sense.

但是要根据对象实例的属性使用其他服务；对我来说，这听起来更像是Factory模式.

But with regard to using a different service based on the properties of an object instance; that sounds more like the Factory pattern to me.
