允许根据文档中的时间戳值读取 FireStore 规则 [英] Allow read in FireStore rules based on timestamp value in document

问题描述

我想创建一个 FireStore 规则，在当前日期超过文档中的时间戳值后授予文档读取权限.

I want to create a FireStore rule that grantes read privilages to documents after the current date has surpassed a timestamp value in the document.

这是一个博客网络应用程序.例如，博主将博文设置为在特定日期向公众开放.

This is for a blog web application. E.G a blogger sets a blog post to be available to the public on a certain date.

从阅读文档来看，这应该有效，但没有.

From reading the documentation this should work, but It dosn't.

service cloud.firestore {
  match /databases/{database}/documents {
    match /Articles/{article}{
   allow read: if request.time.date() < resource.data.date
    }
  }
}

我错过了什么??

推荐答案

我不久前尝试过同样的事情，但发现目前无法实现.

I tried the same thing a while ago, and found out it isn't currently possible.

可以根据特定文档的属性允许/拒绝读取该文档.

It is possible to allow/deny read to a specific document based on a property of that document.

可以允许基于文档中的属性过滤文档的查询，但目前只能基于 request.auth.

It is possible to allow a query that filters documents based on a property in that document, but currently that is only possible based on request.auth.

这意味着很遗憾，您的过滤器目前无法通过安全规则实现.我建议您提交功能请求加入.

This means that unfortunately your filter currently can't be implemented with security rules. I recommend you file a feature request to chime in.

更新 (2018-04-24):这可能现在可以通过 request.time 实现，但我还没有有机会测试呢.在此处查看.

Update (2018-04-24): this might now be possible with request.time, but I haven't had a chance to test yet. Have a look here.
