Question

这是我的控制器动作类

<?php
namespace Felix\HelloMod\Controller\Files;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;

class ProductFiles extends Action
{
    protected $_pagefactory;
    public function _construct(Context $context, PageFactory $pageFactory){
        $this->_pagefactory = $pageFactory;
        return parent::_construct($context);
    }
    public function execute(){
        return $this->_pagefactory->create();
    }
}

我遇到以下错误：

我错过了构造函数方法的双下划线，并运行php bin / magento setup：di：compile并成功了。

<?php
namespace Felix\HelloMod\Controller\Files;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;

class ProductFiles extends Action
{
    protected $_pagefactory;
    public function __construct(Context $context, PageFactory $pageFactory){
        $this->_pagefactory = $pageFactory;
        return parent::__construct($context);
    }
    public function execute(){
        return $this->_pagefactory->create();
    }
}

错误：在控制器操作中在null上调用成员函数create（）
