我正在尝试在Firestore的规则中创建动态连接。
我有一个用户集合和一个角色集合，users集合中的每个用户都有一个'string'字段，该字段与firebase为roles集合中相应角色生成的ID相匹配。
为了实现这一点，我试图动态获取ID，然后从角色中检索适当的数据。
我的代码如下：
**index.php**
<?php include("dbConfig.php");
error_reporting(0);
?>
<?php
session_start();
$companyname=$_SESSION['companyName'];
$tablename=$_SESSION['tableName'];
$ids = $_SESSION["user_id"];
$name=$_GET['name'];
$id = $_GET["id"];
if($_SESSION["user_id"]=="")
{
header("Location:index.php");
}
?>

这不起作用的一个潜在原因是get（）函数是异步的，不要等待前一个函数完成，因此它不能使用它的数据。
非常感谢任何帮助。打开解决方法，数据结构更改等......

对您的示例进行了测试，它对我有用
service cloud.firestore {
match /databases/{database}/documents {
function getRole() {
return get(/databases/$(database)/documents/test-user/$(request.auth.uid)).data.role;
}
function getPermissions(role) {
return get(/databases/$(database)/documents/test-role/$(role)).data.rights;
}
match /test-user/{userid} {
allow read: if true;
allow write: if getPermissions(getRole()) == 'all';
}
}
}
我的测试集的内容是
/test-user/0fludECgWKg88Gn5SjNYPc3Opmx2 (id of my test user) has:
{"role": "tr"}
/test-role/tr has:
{"rights": "all"}
如果/test-role/tr不存在或rights没有值all，则写入请求被拒绝
在您的情况下，也许函数getPermissions的类型是字符串，并且测试需要布尔值。
