如何访问 Laravel 中的验证错误 属性 名称？

Question

我从 Laravel 开始，我尝试对其进行验证并查看每个输入的错误，我已经遍历 $error->all() 但我需要在其下显示每个输入的错误并且我使用此代码 $errors->has('password') 来显示输入有错误，但我也需要显示消息。 我得到 print_r($errors) 并且它 return 这个：

Illuminate\Support\ViewErrorBag Object
(
    [bags:protected] => Array
        (
            [default] => Illuminate\Support\MessageBag Object
                (
                    [messages:protected] => Array
                        (
                            [firstName] => Array
                                (
                                    [0] => The first name field is required.
                                )

                            [lastName] => Array
                                (
                                    [0] => The last name field is required.
                                )

                            [email] => Array
                                (
                                    [0] => The email must be a valid email address.
                                    [1] => The email field is required.
                                )

                            [password] => Array
                                (
                                    [0] => The password field is required.
                                )

                            [password_confirmation] => Array
                                (
                                    [0] => The password confirmation field is required.
                                )

                        )

                    [format:protected] => :message
                )

        )

)

我的问题是我无法访问消息？

AS 根据 Laravel 文档，您可以使用 @error 指令实现相同的

The $errors variable is bound to the view by the Illuminate\View\Middleware\ShareErrorsFromSession middleware, which is provided by the web middleware group. When this middleware is applied an $errors variable will always be available in your views, allowing you to conveniently assume the $errors variable is always defined and can be safely used.

例如

<label for="title">Post Title</label>

<input id="title" type="text" class="@error('title') is-invalid @enderror">

@error('title')
    <div class="alert alert-danger">{{ $message }}</div>
@enderror

Laravel -> Validation -> Displaying The Validation Errors
