Laravel 6错误-照亮\合同\容器\BindingResolutionExc0019目标类不存在

Question

我试图插入数据到我的数据库，但此错误显示：

目标类[App\Http\Controller\Master\Request]不存在。

虽然我的供应商模型和供应商控制器在正确的目录。

这是我的供应商模型源代码（\app\Model\Master）：

<?php

namespace App\Model\Master;

use Illuminate\Database\Eloquent\Model;

class Vendor extends Model
{
    protected $table = 'vendors';

    public function user_modify()
    {
        return $this->belongsTo('\App\User', 'user_modified');
    }
}

这是我的VendorController源代码（\app\Http\Controllers\Master）：

<?php

namespace App\Http\Controllers\Master;

use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;

class VendorController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view("vendor.index");
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view("vendor.create");
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $data = new Vendor();

        $data->vendor_firstname = $request->first_name;
        $data->vendor_lastname = $request->last_name;
        $data->vendor_address = $request->address;
        $data->vendor_phone = $request->contact;
        $data->vendor_firstname = $request->first_name;
        $data->active = $request->vendor_status;
        $data->vendor_modified = Auth::user()->id;

        if($data->save()){
            return redirect()->route('vendor.index');
        }else{
            return redirect()->back();
        }
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

这是我的路线列表：

是什么导致了这个错误？我该如何修复它？尝试运行php artisan config:cache和composer dump autoload，但仍然没有成功。。

添加使用照亮\Http\Request 在控制器文件中。

<?php

namespace App\Http\Controllers\Master;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;

class VendorController extends Controller
{
    public function index()
    {
        return view("vendor.index");
    }
    public function create()
    {
        return view("vendor.create");
    }
    public function store(Request $request)
    {
        $data = new Vendor();

        $data->vendor_firstname = $request->first_name;
        $data->vendor_lastname = $request->last_name;
        $data->vendor_address = $request->address;
        $data->vendor_phone = $request->contact;
        $data->vendor_firstname = $request->first_name;
        $data->active = $request->vendor_status;
        $data->vendor_modified = Auth::user()->id;

        if($data->save()){
            return redirect()->route('vendor.index');
        }else{
            return redirect()->back();
        }
    }
}
