我正在尝试制定一个允许用户查看自己的数据的规则集...
我当前的规则集是：
{
"rules": {
".read": "root.child('users').child(auth.uid).child('admin').val() === true",
".write": "root.child('users').child(auth.uid).child('admin').val() === true",
"users": {
".indexOn": ["active"],
"$user_id": {
".read": "$user_id === auth.uid",
".write": "$user_id === auth.uid"
}
},
"active_alerts": {
".indexOn": "alert_id"
},
"trips": {
".indexOn": "archive",
"$trip_id": {
".read": "data.child('who_called').child('key').val() === root.child('users').child(auth.uid).child('customer').child('key').val()",
"notes": {
"$note_id": {
".read": "data.child('display').val() === true"
}
}
}
}
}
}
user路径中的数据如下所示：
{
"active" : true,
"admin" : false,
"customer" : {
"key" : "-Ldsu71CgIJxh1DVTTCP",
"name" : "Demo Customer"
},
"email" : "emai@email.com",
"last_login" : "2019-05-02T18:34:26.466Z",
"name" : "Demo",
"primary_phone" : "4197460180",
"typeahead" : "demo"
}
和/trips中的匹配项：

customer.key和who_call键匹配，但是用户仍然看不到数据。不知道我在整个规则集中做错了什么。感谢您的帮助！

要让用户看到他们添加的旅程，请像这样使用query-based rules；
"trips": {
".indexOn": "archive",
".read": "auth.uid != null && query.orderByChild == 'who_called/key' &&
query.equalTo == root.child('users/' + auth.uid + '/customer/key').val()",
"$trip_id": {
".read": "data.child('who_called').child('key').val() === root.child('users').child(auth.uid).child('customer').child('key').val()",
"notes": {
"$note_id": {
".read": "data.child('display').val() === true"
}
}
}
}
唯一的限制是，如果不使用规则中指定的查询，就无法访问用户的旅程。这意味着您无法访问此类旅行；
firebase.database().ref('users/USERID/customer/-Ldsu71CgIJxh1DVTTCP)
必须像
一样完成firebase.database().ref('trips').orderByChild('who_called/key')
.equalTo('-Ldsu71CgIJxh1DVTTCP')
我已经尝试过了，而且效果很好。希望对您有帮助
