验证Firebase密钥 [英] Validating a Firebase Key

问题描述

我刚刚开始使用Firebase安全性，可能我缺少一些东西。我需要验证'通知'后，路径（键）是15（后来我会更新15是使用匹配方法的正则表达式，但目前我正在努力执行这个简单的情况）：

  {
rules：{
.write：true，
notifications：{
$年：{
.validate：newData.val（）==='/ 15'，
} 
} 
} 
} 
  

我正在模拟器中测试以下内容：

  / notifications / 15 
  

p>

  {foo：bar} 
  

Firebase模拟器返回：

 尝试写{foo：bar } to / notifications / 15 with auth = {provider：anonymous，uid：a5e08499-c41d-47d0-9df4-64d9af802755} 
 /:.write：true
 => true 
 /notifications/15:.validate：newData.val（）==='/ 15'
 =>假
 
验证失败。 
写入被拒绝。 
  

解决方案

$ c> / notifications / 15 然后 newData.val（）将是该值，而不是关键字。

我不认为有一种方法可以动态地测试键。

I am just getting started with Firebase security and probably I am missing something. I need to validate that after 'notification' the path(key) is 15 (later I will update 15 to be regex using matching method, but currently I am struggling enforcing this simple case):

{
    "rules": {
        ".write": true,
        "notifications": {
          "$year": {
            ".validate": "newData.val() === '/15'",              
          }
        }
    }
}

I am testing in simulator with the following:

/notifications/15

Data I am posting:

{ "foo": "bar" }

The Firebase simulator returns:

Attempt to write {"foo":"bar"} to /notifications/15 with auth={"provider":"anonymous","uid":"a5e08499-c41d-47d0-9df4-64d9af802755"}
    /:.write: "true"
        => true
    /notifications/15:.validate: "newData.val() === '/15'"
        => false

Validation failed.
Write was denied.

解决方案

If you're writing a value to /notifications/15 then newData.val() will be that value, not the key.

I don't think there is a way to test keys dynamically.
