接口不绑定到实现

Question

我正在构建一个 Lumen 应用程序。我正在尝试为我的存储库使用接口。我所有的逻辑都包含在一个 composer 包中。

这是我的 vendor/package/src/app/Providers/PackageServiceProvider.php:

<?php

namespace Vendor\Package\App\Providers;

use Illuminate\Support\ServiceProvider;

class SmsBackendCoreServiceProvider extends ServiceProvider
{
    protected $defer = false;

    public function register()
    {
        $this->app->bind(
            'Vendor\Package\App\Repositories\Contracts\SmsService',
            'Vendor\Package\App\Repositories\Services\SmsJson'
        );
    }

    public function boot()
    {
        $this->app->group(
            ['namespace' => 'Vendor\Package\App\Http\Controllers'],
            function ($app) {
                require __DIR__.'/../../routes/web.php';
            }
        );
    }
}

这是我的 vendor/package/src/routes/web.php:

<?php

$app->get('/sms/send.json', 'JsonController@send');

这是我的 vendor/package/src/app/Http/Controllers/JsonController.php:

<?php

namespace Vendor\Package\App\Http\Controllers;

use Vendor\Package\App\Http\Controllers\BaseController;
use Vendor\Package\App\Repositories\Contracts\SmsService;

class JsonController extends BaseController
{
    public $service;

    public function __construct(SmsService $service)
    {
        $this->service = $service;
    }

    public function send()
    {
        $response = $this->service->sendSms(1, 2, 3);

        return $response;
    }
}

这是我的 vendor/package/src/app/Repositories/Contracts/SmsService.php:

<?php

namespace Vendor\Package\App\Repositories\Contracts;

class SmsService
{
    public function sendSMS($from, $to, $text);
}

最后，这是我的vendor/package/src/app/Repositories/Services/SmsJson。php:

<?php

namespace Vendor\Package\App\Repositories\Services;

use Vendor\Package\App\Repositories\Contracts\SmsService;

class SmsJson implements SmsService
{
    public function sendSMS($from, $to, $text)
    {
        echo 'success';
    }
}

当我尝试访问 http://mydomain.dev/sms/send.json 时，出现此错误：

FatalErrorException in SmsService.php line 7: Non-abstract method Mitto\SmsBackendCore\App\Repositories\Contracts\SmsService::sendSMS() must contain body

我哪里错了？

Answer 1

你的合约声明为class，它必须是一个接口。

接口不绑定到实现

Interface not binding to implementation

php

interface

repository-pattern

laravel
