yii2redactor编辑器上传不了图片[2.0]

一直报403没有访问权限

下面是表单代码：

         <?= $form->field($model, 'content')->widget(Redactor::className(),
                    [
                        'clientOptions' => [
                            'imageManagerJson' => ['/redactor/upload/image-json'],
                            'imageUpload' => ['/redactor/upload/image'],
                            'fileUpload' => ['/redactor/upload/file'],
                            'lang' => 'zh_cn',
                            'plugins' => ['clips', 'fontcolor','imagemanager','video'],
                            'minHeight'=>250,
                        ]
                    ]
                ) ?>

配置文件：

    'modules' => [
        'admin'=>'app\modules\admin',//后台模块引用
        'redactor' => [
            'class' => 'yii\redactor\RedactorModule',
            'uploadDir' => '@webroot/uploads',
            'uploadUrl' => '@web/uploads',
            'imageAllowExtensions'=>['jpg','png','gif'],
             ],
    ],

就帮助
