Zend 3错误：AlbumController :: __ construct（）的参数必须是Album \\ Model \\ AlbumTable的一个实例，没有给出

Question

我正在使用zend 3，并且在尝试列出数据库表中的所有相册时无法解决此错误。 错误是

可捕获的致命错误：传递给Album \\ Controller \\ AlbumController :: __ construct（）的参数1必须是Album \\ Model \\ AlbumTable的实例，没有给出，在C：\\ xampp \\ htdocs \\ zftutorial \\ vendor \\ zendframework \\ zend-servicemanager中调用\\ SRC \\厂\\ InvokableFactory.php

这些是我的文件： AlbumController.php

<?php
namespace Album\Controller;

 {


    private $table;

   public function __construct(AlbumTable $table)
    {
        $this->table = $table;
    }



        public function indexAction()
        {
             return new ViewModel([
            'albums' => $this->table->fetchAll(),
        ]);
        }  



     public function addAction()
     {

Answer 1

在你的module.config.php中你有这个：

 'controllers' => array(
     'invokables' => array(
         'Album\Controller\Album' => 'Album\Controller\AlbumController',
     ),    
  ),

看起来你在这里混淆了一些概念。 一个invokable将是一个在它的构造函数中没有参数的类。 ZF3中不再存在 invokable，就像它们在ZF2中那样。

由于控制器需要一个AlbumTable对象，因此您无法将其用作可调用对象，并且需要创建一个工厂来注入它。 您已经在Module.php中完成了哪些工作。

查看代码，如果从module.config.php中删除这些行，它可能会有效。

您还应该从Module.php中删除getAutoloaderConfig() 。 因为一段时间不推荐使用zend loader来支持composer autoloader。

Answer 2

您需要替换以下代码

   'controllers' => array(
     'invokables' => array(
         'Album\Controller\Album' => 'Album\Controller\AlbumController',
      ),    

   ),

与代码

   'controllers' => [
        'factories' => [
        Controller\AlbumController::class => InvokableFactory::class,
     ],
   ],

从文档中可以看出来

zf3中不再存在invokables。
