云开发怎么获取token?

// 需要给对应的云函数安装 request-promise 依赖

// 云函数入口文件

const cloud = require('wx-server-sdk')

const rp = require('request-promise')

cloud.init()

// 云函数入口函数

exports.main = async (event, context) => {

 const page = event.page

 const scene = event.scene

 //appid和秘钥

 const appid = '***',

 secret = '***';

 const AccessToken_options = {

 method: 'GET',

 url: 'https://api.weixin.qq.com/cgi-bin/token',

 qs: {

 appid,

 secret,

 grant_type: 'client_credential'

 },

 json: true

 };

 //获取AccessToken

 const resultValue = await rp(AccessToken_options);

 const token = resultValue.access_token;

}
