laravel 和验证请求答案

【问题标题】：laravel and validation with requestlaravel 和验证请求

【问题描述】：

我无法在 Laravel 中正确设置验证。在其他功能中，我在控制器中有这个

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Exports\RimborsiExport;

use DB;
use App\Customers;
use App\Claims;
use App\Refunds;
use App\Services;
use App\Http\Requests\RefundsPost;

use Excel;
use DataTables;
use Redirect;
use Response;

class RefundsController extends Controller
{
    public function storeRefundsData(RefundsPost $request){
        dd($request);
        
        //$validated = $request->validated();
        $customers = Customers::create($request->all());
        return back()->with('status', 'Dati Cliente inseriti correttamente');
    }

}

我还定义了一个自定义请求类型

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class RefundsPost 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()
    {
        $rules = [
            'contr_nom' => 'required|max:255',
            'contr_cog' => 'required',
            'polizza' => 'required',
            'email' => 'required',
            'targa' => 'required',
            'iban' => 'required|iban',
            'int_iban' => 'required',
        ];
        return $rules;
    }
    
    public function messages()
    {
    return [
        'contr_nom.required' => "Il Nome Contraente e' obbligatorio",
        'contr_cog.required'  => "Il Cognome Contraente e' obbligatorio",
        'polizza.required'  => "Il numero di polizza e' obbligatorio",
        'email.required'  => "Una mail e' obbligatoria per le comunicazioni",
        'targa.required'  => "La targa e' obbligatoria",
        'data_sin.required'  => "La data sinistro e' obbligatoria",
        'iban.required'  => "Il numero IBAN e' obbligatorio",
        'int_iban.required'  => "L'intestatario dell' IBAN e' obbligatorio",
        'dossier.required'  => "Il numero di dossier e' obbligatorio",
        'cliente.required'  => "Il cliente e' obbligatorio",
        'stato.required'  => "Lo stato del rimborso e' obbligatorio",
        'date_ref.required'  => "La data della richiesta e' obbligatoria",
        ];
    }
}

我有这把刀片，里面有表格

    <div class="container-fluid">
  <form method="POST" action="{{ route('storeRefundsData') }}" novalidate>
      
    {{ csrf_field() }}

我不明白为什么当我单击表单提交按钮在数据库中创建一个新行时，似乎即使它没有进入控制器功能。如果我使用 Request 而不是自定义类型 RefundsPost 它可以工作并将数据存储在数据库中，但显然没有验证。我该如何解决？非常感谢

【问题讨论】：

在您的表单中尝试{{ var_dump($errors) }}，看看是否有任何验证错误。
如果验证失败，它甚至永远不会进入方法......表单请求在从容器中解析时得到验证，这意味着当框架构建此方法的依赖项时，它会创建在调用方法之前请求类

【解决方案1】：

不确定这是否能解决您的问题，但我已经按照我的方式重写了您的函数。您可以指定规则所针对的 http 方法，在本例中我指定了 POST 请求的规则。

RefundsPost -> 规则：

public function rules() {
    $rules = [];

    switch($this->method()) {
        case 'POST': 
        {
            $rules = [
                'contr_nom' => 'required|max:255',
                'contr_cog' => 'required',
                'polizza' => 'required',
                'email' => 'required',
                'targa' => 'required',
                'iban' => 'required|iban',
                'int_iban' => 'required',
            ];
        }

        default:
            break;
    }

    return $rules;
}

在 storeRefundsData 函数中，您应该使用 $request->validated() 并在继续插入时使用它在验证后返回的属性。

RefundsController -> storeRefundsData：

public function storeRefundsData(RefundsPost $request) {

    $attributes = $request->validated();

    $customers = Customers::create($attributes);

    if (!($customers instanceof Customers)) {
        // could not create customer
        return ['result' => false];
    }

    $customers = $customers->fresh(); // if you need to retrieve the objects id

    return ['result' => true];
}

【讨论】：

我按照您的建议进行了修改，但没有任何改变...实际上我可以 dd 例如规则，它向我显示规则数组...嗯，所以在验证 RefundsPost 类期间发生了错误？但是没有显示错误...我无法理解

【解决方案2】：

很遗憾，我无法发表评论。

但是，出于好奇，我认为 iban 规则是习惯性的，对吗？

如果是这样，您可以尝试以下方法：

    public function rules()
    {
        return [
            'contr_nom' => ['required', 'max:255'],
            'contr_cog' => ['required'],
            'polizza'   => ['required'],
            'email'     => ['required'],
            'targa'     => ['required'],
            'iban'      => ['required', new Iban],
            'int_iban'  => ['required'],
        ];
    }

当然，不要忘记在顶部导入规则类：

use App\Rules\Iban;

试试吧，让我们知道，干杯！
