Question

我有以下存储库类

    <?php 
namespace App\Repositories;

use App\Customer;
use App\Comment;
use App\CustomerCode;
use Illuminate\Support\Facades\Request;

class CustomerRepository {

    use ValidatesRequests;

    public function getAll($search=null,Request $request)
    {
        if($search){
            return Customer::where('name','like',"%$search%")->paginate(5);
        }
        return Customer::paginate(5);
    }
}?>

和控制器类

<?php
namespace App\Http\Controllers;
use App\Repositories\CustomerRepository;
use Illuminate\Http\Request;

class CustomerController extends Controller{

    private $customerRepo;

    function __construct(CustomerRepository $customerRepo){
        $this->customerRepo = $customerRepo;
    }

    function index(Request $request){
        return $this->customerRepo->getAll($request->input('search',null));
    }
}

这给了我错误

类型错误：参数2传递给 App \ Repositories \ CustomerRepository :: getAll（）必须是。的实例照亮\支持\外墙\请求，没有给出，调用 C：\ XAMPP \ htdocs中\ avmaxapi \程序\ HTTP \控制器\ CustomerController.php 在第21行

我知道我没有通过第二个论点，但不应该自动注入

我不希望每次都从控制器传递请求对象;

使用use Illuminate\Http\Request;

而不是：use Illuminate\Support\Facades\Request;

以下内容：

<?php 
namespace App\Repositories;

use App\Customer;
use App\Comment;
use App\CustomerCode;
use Illuminate\Http\Request;

class CustomerRepository {

    use ValidatesRequests;

    public function getAll($search=null,Request $request)
    {
        if($search){
            return Customer::where('name','like',"%$search%")->paginate(5);
        }
        return Customer::paginate(5);
    }
}?>

请求在存储库类中注入类
