像这样用 "```" 包住你的代码 排版，就不会乱了。

exports.main = async function (ctx: FunctionContext) {
  // body, query 为请求参数, auth 是授权对象
  const { code } = ctx.body || {}
  if (!code) {
    return { code: 10400, message: 'invalid code' }
  }
  const response = await axios.get(
    'https://api.weixin.qq.com/sns/jscode2session',
    {
      params: {
        appid: WECHAT_MINI_APP_ID,
        secret: WECHAT_MINI_APP_SECRET,
        grant_type: 'authorization_code',
        js_code: code,
      },
    },
  )
  const { openid } = response.data
  if (!openid) {
    return { code: 10400, message: 'invalid code' }
  }
  // 数据库操作
  const db = cloud.database()
  const res = await db.collection('_userprofile').where({
    openid,
