获取request类的protected属性的三种方法

问题来源

问答：这个提示是什么意思？

三种方法

• $request->content
• $request['content']
• $request->input('content')

代码与解释

<?php

namespace App\Http\Controllers\Api;

use App\Http\Requests\Api\ReplyRequest;
use App\Models\Reply;
use App\Models\Topic;
use App\Transformers\ReplyTransformer;

class RepliesController extends Controller
{
    public function store(ReplyRequest $request, Topic $topic, Reply $reply)
    {
        //通过IlluminateRequest基类中的__get()魔术方法调用Arr::get方法来获取值。
        $reply->content = $request->content;

        //因为IlluminateRequest基类实现了ArrayAccess（数组式访问）接口,因此可以像访问数组元素一样
        //访问对象的属性。调用的是基类中的offsetGet方法
        $reply->content = $request['content'];

        //因为IlluminateRequest基类中引入了trait InteractsWithInput，
        //因此可以使用trait中的input方法。最后调用了IlluminateHelpers中的data_get方法
        $reply->content = $request->input('content');

        $reply->topic_id = $topic->id;
        $reply->user_id = $this->user()->id;
        $reply->save();

        return $this->response->item($reply, new ReplyTransformer())
            ->setStatusCode(201);
    }
}
