[英]Neo4j Driver for .NET Readonly mode not working
I have problem with Neo4j Driver for .NET. 我对.NET的Neo4j驱动程序有疑问。
To execute query, i use session with ReadOnly mode and Read transaction, but still i can modify graph via query like: Match (n) where Id(n) = 123 set n.foo = 33 return n;
要执行查询,我使用具有只读模式的会话和Read事务,但是我仍然可以通过查询来修改图形,例如:
Match (n) where Id(n) = 123 set n.foo = 33 return n;
My code: 我的代码:
using (var session = Driver.Session(AccessMode.Read))
{
session.ReadTransaction(tx =>
{
try
{
var queryResult = tx.Run(job);
}
catch (Exception ex)
{
errorMessage = ex.Message;
}
});
}
Why is possible? 为什么可能呢? How resolve this problem?
如何解决这个问题?
The AccessMode.Read
define the type of the session, and this is used only when you are on a cluster mode, to perform session's transactions on a replica server and not on a core server. AccessMode.Read
定义会话的类型,仅当您处于集群模式时,才使用它来在副本服务器上而不是在核心服务器上执行会话的事务。
It doesn't not tell that your session is a readonly one. 它并不能说明您的会话是只读会话。
To have a pure read only access, you need to connect to Neo4j with a read only user. 要具有纯只读访问权限,您需要以只读用户身份连接到Neo4j。
