Firebase - 交易规则

Question

我尝试在Firebase上设置规则，如果uid（abc_x）=== $ account（abc_y），它可以读取数据并且每个人都可以插入，更新数据。但是当我使用的交易，它的报告“错误：PERMISSION_DENIED”

"countchat":{ 
    "$account": { 
     ".read": "$account === auth.uid", 
     ".write": "auth != null", 
    } 
    }, 

Answer 1

从documentation：

When using transactions with Security and Firebase Rules in place, be aware that a client needs .read access in addition to .write access in order to perform a transaction.
