Question

我正在使用当前的Cakephp 3.6.3并通过作曲家附加

composer require maiconpinto/cakephp-adminlte-theme

在Maicon Pinto的教程中，介绍了如何设置控制器和视图。到目前为止一切都很好。现在我正试图通过我网站上的ajax使用json。 route.php中的所有扩展都按照中所述完成 https://book.cakephp.org/3.0/en/views/json-and-xml-views.html

在控制器中我正在使用

$this->loadComponent('RequestHandler');

包括在内。

我现在遇到的问题是，总是抛出MissingTemplateException：

Error: The view for NameController::action() was not found.

这是调试网站输出的一部分：

response => object(Cake\Http\Response) {

    'status' => (int) 200,
    'contentType' => 'application/json',
    'headers' => [
        [maximum depth reached]
    ],
    'file' => null,
    'fileRange' => [[maximum depth reached]],
    'cookies' => object(Cake\Http\Cookie\CookieCollection) {},
    'cacheDirectives' => [[maximum depth reached]],
    'body' => ''

}
paginate => []
components => []
View => object(AdminLTE\View\AdminLTEView) {
    Blocks => object(Cake\View\ViewBlock) {}
    plugin => null
    name => '<Modelname>'
    passedArgs => [
        [maximum depth reached]
    ]
    helpers => [[maximum depth reached]]
    templatePath => '<Modelname>'
    template => 'fill'
    layout => 'default'
    layoutPath => null
    autoLayout => true
    subDir => null
    theme => 'AdminLTE'
    hasRendered => false
    uuids => [[maximum depth reached]]
    request => object(Cake\Http\ServerRequest) {}
    response => object(Cake\Http\Response) {}
    elementCache => 'default'
    viewClass => null
    viewVars => [
        [maximum depth reached]
    ]
    Form => object(AdminLTE\View\Helper\FormHelper) {}
    [protected] _helpers => object(Cake\View\HelperRegistry) {}
    [protected] _ext => '.ctp'
    [protected] _passedVars => [
        [maximum depth reached]
    ]
    [protected] _paths => [
        [maximum depth reached]
    ]
    [protected] _pathsForPlugin => [[maximum depth reached]]
    [protected] _parents => [[maximum depth reached]]
    [protected] _current => null
    [protected] _currentType => ''
    [protected] _stack => [[maximum depth reached]]
    [protected] _viewBlockClass => 'Cake\View\ViewBlock'
    [protected] _eventManager => object(Cake\Event\EventManager) {}
    [protected] _eventClass => 'Cake\Event\Event'
    [protected] _viewBuilder => null
}

那么缺少什么，Cakephp没有请求模板，而是使用文档中预见的普通JsonView？它看起来，因为框架已正确检测到JSON数据并且还希望发送JSON响应。我还尝试将我的动作中的viewBuilder设置为

$this->viewBuilder('Json');

没有任何成功。

Answer 1

我通过更改beforeRender中的类名来找到解决方案：

public function beforeRender(\Cake\Event\Event $event) {
    parent::beforeRender($event);
    if ($this->getRequest()->is('ajax') || $this->getRequest()->is('json')){
        $this->viewBuilder()->setClassName('Json');
    }
}

现在我的格式正确。
