unable to sign off immediately after sign in

登陆之后无法直接点“退出登陆”来退出。 具体error如下

VM628 WAService.js:1 Uncaught (in promise) Error: errCode: -1  | errMsg: collection.doc:fail docId must not be empty; at collection.doc api; 
    at new u (VM628 WAService.js:1)
    at d (VM628 WAService.js:1)

    at Generator.prototype.<computed> [as next] (runtime.js? [sm]:118)

    at index.js:3

看起来是因为userinfo中的_id 并不存在。 但是重新打开这个页面就可以了

对应的代码是/pages/user/index.js 中

// 退出登录
  async bindLogout() {
    const userInfo = this.data.userInfo

    await this.db.collection('users').doc(userInfo._id).update({
      data: {
        expireTime: 0
      }
    })

    this.setUserInfo()
  }
