问题描述

我正在使用Flask开发服务器环境使用Flask，Gevent和Web套接字进行项目.我使用了flask_login.在这里

Am doing a project with Flask, Gevent and web socket using flask development server environment. I used flask_login. Here

1. 如何获取每个连接的唯一会话ID?
2. 我想将SessionID存储在数据库中，并在客户端断开连接后将其删除.

3. 如何获得活动连接总数

1. how can get i get the Unique Session ID for each connection?
2. I want to store the SessionID in the Database and delete it once client disconnects.

3. How to get total active connections

from flask_login import * 
login_manager = LoginManager()
login_manager.setup_app(app)

@app.route("/", methods=["GET", "POST"]) 
def login():
    login_user([username], remember):    

@app.route("/logout") 
@login_required 
def logout(): 
    logout_user() 

推荐答案

没有会话ID.

Flask中的会话只是cookie的包装.您保存在上面的内容经过数字签名，并以cookie的形式发送给客户端.当您发出请求时，该cookie将发送到您的服务器，然后在Python对象中进行验证和转换.

Sessions in Flask are simply wrappers over cookies. What you save on it it's digitally signed and sent as a cookie to the client. When you make a request, that cookie is sent to your server and then verified and transformed in a Python object.

AFAIK，Flask登录将会话ID保存在会话中.

AFAIK, Flask-Login saves on the session the user ID.

要获得总的活动连接，您可以:

To get total active connections, you can:

1. 登录时，生成一个唯一的ID并将其保存在会话中(例如，flask.session['uid'] = uuid.uuid4())，然后将其保存在数据库中.
2. 注销时，从会话(del flask.session['uid'])以及您的数据库中删除该唯一ID.
3. 使用您喜欢的方法(ORM/Raw SQL)检索活动会话的数量

1. At login, generate an unique id and save it on the session (flask.session['uid'] = uuid.uuid4(), for example), then save it on your database.
2. At logout, delete that unique id from the session (del flask.session['uid']) and also from your database.
3. Retrieve the count of active sessions using your favourite method (ORM/Raw SQL)
