import dd from "gdt-jsapi"

import * as ddEnv from 'dingtalk-jsapi'

     sureEmpower() {
                /* 判断是否钉钉环境 */
                if (ddEnv.env.platform === 'notInDingTalk') {

                            type: 'error',
                        })
                    }, 100)

                    setTimeout(() => {
