Question

我有一个具有以下功能的控制器

public function completeRegistration(Request $request)
{
        $yy = $request->exp_year;
        $mm = $request->exp_month;
        $cardnum = $request->cardnum;
        $cvc = $request->cvc;
}

我希望能够做到这样的事情

public function completeRegistration(Request $request)
{
        $yy = $request->exp_year;
        $mm = $request->exp_month;
        $cardnum = $request->cardnum;
        $cvc = $request->cvc;

    if(billUser($cardnum, $mm, $yy, $cvc))
    {
        echo "charge success";
    }
    else 
    {
        echo "uh something was wrong";
    }
}

自从5.2不再拥有命令和处理程序后，我的选择是什么？其他控制器需要能够与我的支付网关的API进行交互。我需要一个与支付相关的功能列表，我可以轻松地将其调用到任何控制器中。

我认为您需要提供服务：

# app/Services/Payment/Payment.php

<?php
namespace App\Services\Payment;

class Payment 
{
    public function billUser($cardnum, $mm, $yy, $cvc)
    {
        // Your logic here
    }
}

然后，如果您想要将此服务“Laravel方式”集成，则需要创建服务提供商：

# app/Services/Payment/PaymentServiceProvider.php

<?php
namespace App\Services\Payment;

use Illuminate\Support\ServiceProvider;

class PaymentServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton('Payment', function($app) {
            return new Payment();
        });
    }
}

然后在config/app.php注册此服务提供商：

return [

    ...

    'providers' => [

        ...

        App\Services\Payment\PaymentServiceProvider::class,

        ...

    ],

    ...

];

然后，您可以在控制器中访问它：

<?php
namespace App\Http\Controllers;

public function completeRegistration(Request $request)
{
    $yy = $request->exp_year;
    $mm = $request->exp_month;
    $cardnum = $request->cardnum;
    $cvc = $request->cvc;

    if(app('Payment')->billUser($cardnum, $mm, $yy, $cvc))
    {
        echo "charge success";
    }
    else 
    {
        echo "uh something was wrong";
    }
}

然后，您可以进一步为您的服务创建Facade：

# app/Services/Payment/PaymentFacade.php

<?php
namespace App\Services\Payment;

use Illuminate\Support\Facades\Facade;

class PaymentFacade extends Facade
{
    protected static function getFacadeAccessor()
    {
        return 'Payment';
    }
}

要使用它，您还需要将其注册到app/config.php文件中：

return [

    ...

    'aliases' => [

        ....

        'Payment' => App\Services\Payment\PaymentFacade::class,
    ],

];

并在代码中的任何位置使用它：

<?php
namespace App\Http\Controllers;

use Payment;

public function completeRegistration(Request $request)
{
    $yy = $request->exp_year;
    $mm = $request->exp_month;
    $cardnum = $request->cardnum;
    $cvc = $request->cvc;

    if(Payment::billUser($cardnum, $mm, $yy, $cvc))
    {
        echo "charge success";
    }
    else 
    {
        echo "uh something was wrong";
    }
}

我希望这有帮助！

如何在Laravel 5.2中执行外部功能？
