Laravel 8.12 不显示错误信息

Question

我不明白为什么错误消息没有显示在 laravel 的表单控件中。我的错误是什么？

虽然我在满足以下条件时可以收到“okey”消息，但我无法清楚地理解错误消息没有显示，因为它不满足条件。

use App\Http\Controllers\Website\contact;

Route::get('/register', [contact::class, 'index'])->name('register');

如果你愿意用另一种方法来解决你的问题，或者一个快速的解决方案，你可以直接使用 Validator 类， 首先将其添加到您的控制器中， use Illuminate\Support\Facades\Validator; 那么，

public function post(Request $request)
    {
        $validator = Validator::make($request->all(),[
            'name' => ['required', 'max:10'],
            'email' => ['required'],
        ]);
        
        if ($validator->fails()) {
            return redirect()->back()
                        ->withErrors($validator);
        }

        echo "okey";
    }
