Laravel 拉威尔：为什么验证消息不显示？

我在主机上使用Laravel5.4。我的验证方法正在工作，但它不显示消息。我做了显示错误所需的所有操作，但它不起作用

@if($errors->has('recipient'))
<div class="form-group">
<label class="col-lg-2 control-label"></label>  
<div class="col-lg-10">                     
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->get('recipient') as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
</div>
</div>
@endif

我的验证程序代码：

protected function validator(array $data)
{        
    return Validator::make($data, [

        "$this->recipient" => [
            'sometimes',
            'required',
            'email',
            'exists:users,email',
            Rule::notIn([auth()->user()->email])
        ],

        "$this->subject" => 'sometimes|required|min:10',

        "$this->message" => 'sometimes|required|min:50',

    ], $this->validator_messages());
}

我的路线：

Route::get('/compose', 'InboxController@compose')     ->name('compose');
Route::post('/compose', 'InboxController@send');

转储的结果（$errors）

：

您需要更改：

"$this->recipient"
"$this->subject" 
"$this->message"

要解决当前问题，请将

$errors->get（'recipient'）

更改为

$errors->all（）

应该是这样的：

@foreach ($errors->all() as $error)
   <li>{{ $error }}</li>
@endforeach

之后，您可以将类型从Request更改为CustomRequest

public function send(CustomRequest $request)
{
   $this->create($request->all());
   return redirect($this->redirectToAfterSendMessage);
}

在CustomRequest.php中，提取验证逻辑，如下所示：

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class CustomRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name' => 'required',
            'email' => 'required',
            'message' => 'required',

        ];
    }

    public function messages()
    {
        return [
            'name.required' => 'Name is required.',
            'email.required' => 'Email is required.',
            'message.required' => 'Message is required.',
        ];
    }
}

请包括执行验证的代码以及控制器方法。请显示
{{dd（$errors）}
为什么使用
“$this->recipient”
？仅使用“收件人”

！它应该对你有用！我已删除但未工作显示消息，$errors返回null。但是验证正在工作。在我的本地站点中，

$this->recipient

也在工作。在主机上也可以运行此代码，但不会返回messages@MaxNet我更新了我的答案。如果它解决了你的问题，请记下我的答案是正确的。如果有帮助，请投票表决。如果你还有什么问题，告诉我。

@foreach ($errors->all() as $error)
   <li>{{ $error }}</li>
@endforeach

php artisan make:request CustomRequest

public function send(CustomRequest $request)
{
   $this->create($request->all());
   return redirect($this->redirectToAfterSendMessage);
}

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class CustomRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name' => 'required',
            'email' => 'required',
            'message' => 'required',

        ];
    }

    public function messages()
    {
        return [
            'name.required' => 'Name is required.',
            'email.required' => 'Email is required.',
            'message.required' => 'Message is required.',
        ];
    }
}
