从数据库动态控制Firebase存储安全规则 [英] Dynamic control of firebase storage security rules from database

问题描述

我想对数据库中的存储规则进行动态控制.我的意思是它应该检查数据库节点以允许读取或写入. 但是我找不到办法. 例如

I want to have a dynamic control on storage rules from database. I mean it should check database nodes to allow read or write. But I cannot find a way. For example

match /files/{fileKey} {
  allow read: // here will check db to get result of allowRead 
  allow write: // here will check db to get result allowWrite
}

db:

files: {
  fileKey1: {
    allowRead: true,
    allowWrite: false
},
  fileKey2: {
    allowRead: true,
    allowWrite: true
}

推荐答案

无法从Firebase存储安全规则中检查Firebase数据库.

There is no way to check the Firebase Database from Firebase Storage security rules.

您必须将必要的信息嵌入到存储安全规则中，或者

You'll have to either embed the necessary information into your Storage security rules, or embed it in the user's token as a custom claim.
