【问题描述】：
我尝试使用验证器通过 laravel 验证数据，并将其插入到名为 offer 的表中，我确信这是真的，我也使用它来验证 这是我的代码 web.php
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\Front\UserController;
use App\Http\Controllers\CrudController;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!

*/
Route::get('/', function () {
return view('welcome');
});
Route::namespace('Front')->group(function(){
Route::get('users',[UserController::class,'showAdminName']);
});
Auth::routes(['verify' =>true]);
Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home')->middleware('verified');
Route::get('fillable',[\App\Http\Controllers\CrudController::class,'getOffers']);
Route::group(['prefix'=>'offers'],function(){
// Route::get('store',[CrudController::class,'store']);
Route::get('create',[CrudController::class,'createview']);
Route::post('store',[CrudController::class,'store']);
});
CrudController.php
<?php
namespace App\Http\Controllers;
use App\Models\Offer;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class CrudController extends Controller
{
public function getOffers(){
return Offer::select('id','name')->get();
}
public function createview(){
return view('offers.create');
}
public function store(Request $request){
// validate data
$validate = Validator::make($request->all,[
'name' => 'required|min:5|max:10|unique:offers,name',
'price' => 'required|numeric',
'details' => 'required'
]);
// insert
Offer::create([
'name' => $request->name,
'price' => $request->price,
'details' => $request->details,
]);
return back()->with('offer_created','Saved succesfully');
}
}

它给了我这个错误
Illuminate\Validation\Factory::make(): 参数 #1 ($data) 必须是 类型数组，给定空值，调用 C:\xampp\htdocs\starter\vendor\laravel\framework\src\Illuminate\Support\Facades\Facade.php 在第 261 行
