You're using

 "posts": {
    "$uid": {
        ".read": true,
        ".write": "auth != null && 
               auth.uid == data.child('userid').val()"
    }
 }

to look up the UID, which is the data as is exists

/posts/-Hhnfdb743HvGdF/userid/v5s8fd8f7

before

this operation. To get the data as it exists

Answer 1

:dataSee the Firebase documentation on existing data vs new data.我想只允许这个userid写数据，所以我试了一下。问题是它总是拒绝，即使userid和auth相同，有什么办法吗？newData谢谢

auth.uid == newData.child('userid').val()"
