Php 调用未知方法：yii2mod\cms\controllers\CmsController:：setInstance（）

我不明白为什么会发生这种错误

调用cms时获取错误

http://localhost/yii-cms/web/cms

调用未知方法：

yii2mod\cms\controllers\CmsController:：setInstance（）

我正在尝试使用

yii2 cms

CMS控制器

是错误通过遵循正确的配置步骤解决

由于未执行配置第二步，出现错误

2） 通过以下代码将新规则类添加到应用程序配置中的urlManager数组中：

'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ], 

'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

 'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

您需要执行的完整配置：

1） 要首先使用此扩展，您需要配置comments扩展，然后必须在应用程序中配置主配置：

'modules' => [
        'admin' => [
            'controllerMap' => [
                'cms' => 'yii2mod\cms\controllers\CmsController'
                // You can set your template files
                // 'layout' => '@app/modules/backend/views/layouts/main',
                // 'viewPath' => '@app/modules/backend/views/cms/',
            ],
        ],
    ],

'modules' => [
        'admin' => [
            'controllerMap' => [
                'cms' => 'yii2mod\cms\controllers\CmsController'
                // You can set your template files
                // 'layout' => '@app/modules/backend/views/layouts/main',
                // 'viewPath' => '@app/modules/backend/views/cms/',
            ],
        ],
    ],

You can then access to management section through the following URL:

http://localhost/path/to/index.php?r=admin/cms/index

然后，您可以通过以下URL访问管理部分：


2） 通过以下代码将新规则类添加到应用程序配置中的urlManager数组中：

'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ], 

'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

 'components' => [
        'urlManager' => [
            'rules' => [
                ['class' => 'yii2mod\cms\components\PageUrlRule'],
            ]
        ],
    ],

3） 添加到SiteController（或通过urlManager中的$route param进行配置）：

现在，您可以通过管理面板创建自己的页面，并通过每个页面的url访问它们。
您似乎正在使用站点组件中的cms扩展

在
web.php
文件中，添加以下内容：


“组件”=>[
...
‘i18n’=>[
“翻译”=>[
'*' => [
'class'=>'yii\i18n\PhpMessageSource'，
“基本路径”=>“@app/messages”
'sourceLanguage'=>'en'，
],
],
],
]
...,
“controllerMap”：=>[
'cms'=>'yii2mod\cms\controllers\CmsController'
],

注意：您应该排除有关在管理模块中将其配置为组件的路径，因为您无论如何都不使用它

如果您是在模块中使用它，那么自述文件中记录的步骤对您来说很好。
我有以下内容，它的工作非常出色

设置实例由于无法找到给定的类而发生错误，这可能是由于未进行配置

遵循配置链接

            'controllerMap' => [
                'cms' => 'yii2mod\cms\controllers\CmsController'
                // You can set your template files
                // 'layout' => '@app/modules/backend/views/layouts/main',
                // 'viewPath' => '@app/modules/backend/views/cms/',
            ],
        ],
    ],

'modules' => [
        'admin' => [
            'controllerMap' => [
                'cms' => 'yii2mod\cms\controllers\CmsController'
                // You can set your template files
                // 'layout' => '@app/modules/backend/views/layouts/main',

            ]
        ],
    ],

3） 添加到SiteController（或通过urlManager中的$route param进行配置）：

显示相关的控制器代码。。please@scaisEdge我已经更新了
setInstance（）
是
yii\base\Module
类中的一个方法。您是否正确设置了配置文件？您是否在某处定义了模块？显示您的错误堆栈跟踪将有所帮助。是的，我已在配置文件@slayvinsame answer中定义了模块，但您已在出现此类错误时告诉我原因。谢谢
