如何清理laravel 5.X请求输入? [英] How can I sanitize laravel 5.X Request inputs?

问题描述

我有MyRequest.php类扩展了App\Http\Requests\Request.我想trim()验证之前的每个输入，因为在其后面带有空格的电子邮件不会通过验证.

I have MyRequest.php class extending App\Http\Requests\Request. I want to trim() every input before validation because an e-mail with a space after it does not pass validation.

但是sanitize()已从src/Illuminate/Foundation/Http/FormRequest.php

推荐答案

我刚遇到相同的问题.
我想向您展示另一种不使用extends但使用traits的方法. (我将从Tarek Adam获得示例类).

I just came across for the same problem.
I'd like to show you another way of doing it without extends but with traits. ( I will take the Example Classes from Tarek Adam ).

PHP 特质类似于将被注入到二手课.一个主要的区别是，Trait不需要像extends那样的任何依赖项.这意味着您可以将一个特征用于多个类，而不仅仅是一个类.适用于控制器，请求和任何您喜欢的东西.

PHP Traits are like functions which will be injected into the used class. The one main difference is that a Trait doesn't need any dependency like a extends do. This means you can use a trait for more then just one class e.x. for Controllers, Requests and whatever you like.

Laravel在BaseController中提供了一些特征，我们可以做同样的事情.

Laravel provides some traits in the BaseController, we can do the same.

在\App\Traits\SanitizedRequest.php中的文件中创建一个特征.您可以在无关紧要的任何地方创建它.您必须确保提供正确的名称空间.

Create a trait as file in \App\Traits\SanitizedRequest.php. You can create it anywhere it doesn't matter really. You have to provide the correct namespace for sure.

namespace App\Trait;

trait SanitizedRequest{

    private $clean = false;

    public function all(){
        return $this->sanitize(parent::all());
    }


    protected function sanitize(Array $inputs){
        if($this->clean){ return $inputs; }

        foreach($inputs as $i => $item){
            $inputs[$i] = trim($item);
        }

        $this->replace($inputs);
        $this->clean = true;
        return $inputs;
    }
}

在您的请求中，可以将特征与use SanitizedRequest关键字一起使用.

In your Request you can use the trait with use SanitizedRequest keyword.

namespace App\Http\Requests\Forms;

use App\Http\Requests\Request;
use App\Trait\SanitizedRequest; // Import the Trait 

class ContactRequest extends Request {
    use SanitizedRequest; // This line adds all the Trait functions to your current class

    public function authorize(){ return true; }
    public function rules(){ return []; }
}
