Get value in url in FormRequest form validator

I recently started a blog and wrote "elegant" code according to the Laravel project development specifications.
The routing of the project is probably like this

Route::get(&#39;/keywords&#39;,&#39;KeywordsController@index&#39;);
Route::get(&#39;/keywords/create&#39;,&#39;KeywordsController@create&#39;);
Route::post(&#39;/keywords/store&#39;,&#39;KeywordsController@store&#39;);
Route::delete(&#39;/keywords/{id}&#39;,&#39;KeywordsController@destory&#39;);
Route::get(&#39;/keywords/{id}/edit&#39;,&#39;KeywordsController@edit&#39;);
Route::put(&#39;/keywords/{id}&#39;,&#39;KeywordsController@update&#39;);

The validator uses the FormRequest base class to verify. The code is as follows

<?php

namespace App\Http\Requests;use Illuminate\Validation\Rule;class KeywordRequest extends Request{
    public function rules()
    {
        //$this->route(&#39;id&#39;) 获取url占位符为id的数据
        switch ($this->method())
        {
            case  &#39;POST&#39; :
            {
                return [
                  &#39;keyword&#39; => &#39;required|unique:keywords&#39;
                ];
            }
            case &#39;PUT&#39;:
            case &#39;PATCH&#39;:
            {
              return [
                &#39;keyword&#39; => [
                  &#39;required&#39;,
                  Rule::unique(&#39;keywords&#39;)->ignore($this->route(&#39;id&#39;)),
                ],
              ];
            }
            case &#39;DELETE&#39;:
            case &#39;GET&#39;:
            default:
            {
                return [];
            }
        }
    }
    public function messages()
    {
       return [
           &#39;keyword.required&#39; => &#39;关键字不能为空&#39;,
           &#39;id.required&#39; => &#39;id不能为空&#39;,
           &#39;keyword.unique&#39; => &#39;关键字已存在,请重新填写&#39;
       ];
    }}

Verification is performed according to the request method
In order to maintain the standard, when I updated the request, I did not put the id in the form, but only in the URL. There is also such a method in the official documents.

use Illuminate\Validation\Rule;
Validator::make($data, [
    &#39;email&#39; => [
        &#39;required&#39;,
        Rule::unique(&#39;users&#39;)->ignore($user->id),
    ],]);

But I never knew how to get this $user->id. I finally found a method online that met my requirements

$this->route(&#39;id&#39;)
