在Meteor.js中查找当前会话ID [英] Find the Current Session Id in Meteor.js

问题描述

如何在客户端上找到当前的会话ID？

How do you find the current Session Id on the client?

我能够得到似乎是最后一个会话ID，而不是当前的会话ID。

I am able to get what seems like the last session id, not the current session id.

console.log(Meteor.default_connection._lastSessionId)

推荐答案

这个措辞有点令人困惑，但 _lastSessionId 是当前的会话ID。

The wording for this is a bit confusing, but _lastSessionId is the current session id.

它只被调用，因为如果客户端断开连接并寻求重新连接，则需要使用上一个会话ID重新建立会话。

It is only called this because if the client is disconnected and seeks to reconnect it wants to re-establish the session with the last session id.

客户端将重新连接如下消息：

The client would reconnect with a message like this :

{"msg": "connect ", "session": "ERoZSR3R3f8zBQ6Ry", "version": "pre1","support":["pre1"]}

会话使用lastSessionId值。然后，这用于重新建立先前的连接。

The session uses the lastSessionId value. This is then used to re-establish the previous connection.

这是唯一一种在重新连接时分配新会话ID的情况。该会话或服务器的会话已过期。

This is the only case where a new session id would be assigned on a reconnection. That or the session is expired off the server.

如果服务器重新启动，则刷新缓存并且它将不再识别会话，并且新的会话ID将是已分配。

If the server restarts it's cache is refreshed and it wouldn't recognize the session anymore, and a new session id would be assigned.
