菜鸡提问 在<unicloud-db>中发action怎么携带参数，并且在action中接受，如下面的阅读数加1实例

vue代码：

<view class="detail">  
    <unicloud-db ref="udb" v-slot:default="{data, loading, error, options}" collection="notice" loadtime="onready"  
        action="cnt_add_action" :where="where" getone="true">  
        <view v-if="error">{{error.message}}</view>  
        <view v-else-if="data">  
            <view class="detail-title">  
                标题:{{data.title}}  
            </view>  
            <view class="detail-header">  
                <view class="detail-header__logo">  
                    <image src="../../../static/logo.png" mode="aspectFill"></image>  
                </view>  
                <view class="detail-header__content">  

                    <view class="detail-header__content-info">  
                        <uni-dateformat :date="data.submit_time" />  
                        <text>{{data.browse_count}} 浏览</text>  
                    </view>  
                </view>  
            </view>  
        </view>  
    </unicloud-db>  
</view>

cnt_add_action.js

const db = uniCloud.database();  
const dbCmd = db.command  
module.exports = {  
    before: async (state, event) => {  
                 //如何接受参数文章的_id  
        // let _id=event.command.$db[1].$param[0]._id.operands[0]  
        // await db.collection('notice').doc(_id).update({  
        //  browse_count:dbCmd.inc(1)  
        // })  

    },  
    after: async (state, event, error, result) => {  
        if (error) {  
            throw error  
        }  
        return result  
    }  
}
