Question

我在yii2高级模板上处理小模块，我需要上传图像。上传工作正常，但当我尝试将上传的图片广告在视图中呈现时，我收到此错误：

An Error occurred while handling another error:

仅对请求图像发生这种情况，页面正确呈现，控制器行为为：

public function behaviors()
{
    $behaviors = parent::behaviors();
    $behaviors['access'] = [
        'class' => AccessControl::className(),
        'rules' =>[
            [
                'allow' => true,
                'roles' => ['@'],
            ],
        ],
        'verbs' => [
            'class' => VerbFilter::className(),
            'actions' => [
                '*' => ['post', 'get']
            ],
        ],
    ];

    return $behaviors;
}

图像是我用于创建和更新的表单上的请求： ...

<?php if($model->imageFile):?>
    <span><?=$model->imageFile ?></span>
    <?= Html::img($model->imageFile) ?>
<?php endif ?>

...

如果我在另一个浏览器标签中打开图像的src我不是同一个问题，权限的文件设置为777以防止错误。我如何才能看到页面内的图像？感谢

您可能没有为错误操作添加规则。添加以下规则以授予对SiteController上的actionError的访问权限：

'rules'=>[
//...
    [
        'actions'=>['error'],
        'allow'=>true,
    ],
//...
]

获取图像时，Yii2 AccessControl权限被拒绝
