路由代码

const { deleteMenu, createMenu } = require("../utils/menu")

router.get("/menu", async (req, res, next) => {
  try {
    // 先获取access_token
    const { access_token } = await accessToken.fetchAccessToken()
    // 一定要记得创建前先删除菜单
    await deleteMenu(access_token)
    // 创建菜单
    await createMenu(access_token)
    res.send({
      state: "success",
      msg: "创建菜单成功",
    })
  } catch (error) {
    console.log("自定义菜单创建失败：" + error)
    next(error)
  }
})

核心创建菜单代码

const rp = require("request-promise-native") //发送请求

class Menu {
  constructor() {}
  deleteMenu(access_token) {
    const url = `https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=${access_token}`
    return new Promise((resolve, reject) => {
      rp({ method: "GET", url, json: true })
        .then((result) => {
          console.log("删除菜单成功")
          console.log(result)
          resolve()
        })
        .catch((err) => {
          console.log("删除菜单失败")
          console.log(err)
          reject(err)
        })
    })
  }
  createMenu(access_token) {
    const url = `https://api.weixin.qq.com/cgi-bin/menu/create?access_token=${access_token}`
    const menuData = {
      // 创建一个按钮，点击跳转到对应url
      button: [
        {
          type: "view",
          name: "微信授权登录",
          url: "xxxx",
        },
      ],
    }

    const options = {
      url,
      method: "POST",
      json: true,
      headers: {
        "content-type": "application/json",
      },
      body: menuData,
    }

    return new Promise((resolve, reject) => {
      rp(options)
        .then((result) => {
          console.log("创建菜单成功")
          console.log(result)
          resolve()
        })
        .catch((err) => {
          console.log("创建菜单失败")
          console.log(err)
          reject(err)
        })
    })
  }
}

const menu = new Menu()

module.exports = menu
