Laravel抽象類庫

Question

您好我試圖在laravel中實現存儲庫模式與抽象類有一些基礎功能，這是我新來的。

我就行了AbstractRepository->創建（$請求）獲得

Parse error:syntax error, unexpected '->' (T_OBJECT_OPERATOR)

; 當我從存儲庫中的抽象調用函數。下面是代碼

AbstractRepository.php

<?php 

    namespace App\Abstracts; 

    use App\Exceptions\NoResourceFoundException; 
    use App\Exceptions\ResourceNotFoundException; 

    abstract class AbstractRepository 
    { 

     /** 
     * @var Model 
     */ 
     protected $model; 

     /** 
     * @var array 
     */ 
     public $errors = []; 

     /** 
     * @param Model $model 
     */ 
     public function __construct(Model $model) 
     { 
      $this->model = $model; 
     } 

     public function create(array $data) 
     { 
      return $this->model->create($data); 
     } 
    } 

ReportRepositoryInterface.php

<?php 

namespace App\Interfaces; 

interface ReportRepositoryInterface { 

    public function createReport (array $data); 
} 
?> 

ReportRepository.php

<?php 

namespace App\Repositories; 

use App\Interfaces\ReportRepositoryInterface; 
use App\Models\Report; 
use App\Services\ApiResponse; 
use Illuminate\Http\Request; 
use App\Abstracts\AbstractRepository; 

class ReportRepository implements ReportRepositoryInterface { 

    public function createReport(array $request){ 
    AbstractRepository->create($request); 
    return ApiResponse::responseData($request, 'Record successfully created!'); 
    } 
} 

?> 

ReportsController.php

<?php 

namespace App\Http\Controllers; 

use Illuminate\Http\Request; 
use App\Interfaces\ReportRepositoryInterface; 
use Illuminate\Support\Facades\Log; 

class ReportsController extends Controller 
{ 

    public function __construct(ReportRepositoryInterface $report, Request $request) 
    { 
    $this->report = $report; 
    $this->request = $request; 
    } 

    public function createReport() 
    { 
    $data = $this->request->all(); 
     return $this->report->createReport($data); 
    } 
} 

任何人都可以啓發我嗎？謝謝

當一個類是abstract這意味着你不能直接創建該類的一個實例，而不是你可以調用該類的方法而不創建該類的一個實例，這將是一個static方法。一個abstract類是爲了擴展。在這種情況下，您的ReportRepository需要被修改爲：

class ReportRepository extends AbstractRepository implements ReportRepositoryInterface { 

    public function createReport(array $request){ 
     $this->create($request); 
     return ApiResponse::responseData($request, 'Record successfully created!'); 
    } 
} 

看看手冊中的abstraction和static方法可見手冊。
