yii2-redactor 图片上传问题

yii2-redactor无法插入图片，生成的img标签无src值

配置如下:

web.php

    'modules' => [
        'redactor' => [
                'class' => 'yii\redactor\RedactorModule',
                'uploadDir' => '@webroot/path/to/uploadfolder',
                'uploadUrl' => '@web/path/to/uploadfolder',
                'imageAllowExtensions'=>['jpg','png','gif']
            ],
    ],

veiw

     <?= $form->field($model, 'content')->widget(\yii\redactor\widgets\Redactor::className(),
        [
            'clientOptions' => [
                'imageManagerJson' => ['/redactor/upload/image-json'],
                'imageUpload' => ['/redactor/upload/image'],
                'fileUpload' => ['/redactor/upload/file'],
                'lang' => 'zh_cn',
                'plugins' => ['clips', 'fontcolor','imagemanager']
            ]
        ]
        ) ?>

插入图片后生成的HTML代码为：

<p><img>
</p>

求大神！
