Zend Framework 3教程错误

Question

我昨天才开始做Zend Framework 3教程

但是，在这一步：

当我在modules.config.php中有模块‘相册’时，我有以下错误：

Zend\ServiceManager\Exception\ServiceNotFoundException
/var/www/api/vendor/zendframework/zend-servicemanager/src/AbstractPluginManager.php:133

有人能帮我吗，我真的不明白，我只是跟着课文走。谢谢！

namespace Album;

use Zend\Router\Http\Segment;

Answer 1

在您的AlbumController类中，您调用了getServiceLocator()，但是您不应该这样做。您确定您正在遵循官方的ZF3教程吗？本教程中没有getServiceLocator()调用。您不应该必须从控制器中检索services，因为您应该在控制器中注入必要的服务(这是ZF3的方法)。

我强烈建议您从代码中删除本教程中没有的所有内容。一旦您完成了它(包括深度教程)，您就会明白为什么不需要从控制器中调用一些getServiceLocator()方法.

Answer 2

'view_manager‘=> [ //设置视图'display_not_found_reason’=> true，//它控制是否显示有关页面未找到错误的详细信息。'display_exceptions‘=> true，//定义是否显示有关未处理异常及其堆栈跟踪的信息。

    //*** the two parameters shown above MUST be set to FALSE in production systems, because you don't want the site visitors see the details about errors in you site. 
    ////However, you will still be able to retrieve the detailed information from Apache's error.log file

    'doctype'                  => 'HTML5',
    'not_found_template'       => 'error/404',  //defines the TEMPLATE NAME for the 404 error(it will be searched on template_map)
    'exception_template'       => 'error/index', //defines the TEMPLATE NAME for the unhandled exception error 
    'template_map' => [
        'layout/layout'           => __DIR__ . '/../view/layout/default.phtml',

        'application/index/index' => __DIR__ . '/../view/application/index/index.phtml',            
        'error/404'               => __DIR__ . '/../view/error/404.phtml',
        'error/index'             => __DIR__ . '/../view/error/index.phtml',
    ],
    'template_path_stack' => [
        __DIR__ . '/../view',
    ],
],

正如您在上面的行中所看到的，您的代码有一些错误。嵌套作为密钥，您在属于'view_manager‘键的“template_path_stack”键中的路径。试着改变你的代码，祝你好运。
