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

我正在使用zend 3并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Zend 3错误：对AlbumController :: __ construct（）的参数必须是Album Model AlbumTable的一个实例，没有给出

可捕捉致命错误：传递给Album \ Controller \ AlbumController :: __ construct（）的参数1必须是Album \ Model \ AlbumTable的实例，未给出，在C：\ xampp \ htdocs \ zftutorial中调用\供应商\ zendframework \ Zend的-的ServiceManager的\ src \厂\ InvokableFactory.php

这些都是我的文件： AlbumController.php

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



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

在你module.config.php你有这样的：

'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invokeable可以是一个在其构造函数中没有参数的类。 ZF3中也有invokables no longer exist，就像它们在ZF2中一样。

由于控制器需要一个AlbumTable对象，因此不能将其用作可调用对象，并且需要创建一个工厂来注入它。你已经在Module.php中完成了。

看着你的代码，它可能会工作，如果你从module.config.php中删除这些行。

您还应该从Module.php中删除getAutoloaderConfig()。一段时间以来，zend加载程序不赞成使用作曲家自动加载器。

您需要的代码

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

由于从docs

invokables在ZF3不再存在替换下面的代码

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

    ),

。
