flask-session组件：将cookie中的session值存放至redis

1、安装

pip install flask-session

2、使用

方式一：

import redis

pool = redis.ConnectionPool(host="10.0.0.10", password="azn950626", port=6379)
single_pool = redis.Redis(connection_pool=pool)

redis_pool.py

from flask import Flask, session
from flask_session import RedisSessionInterface

app = Flask(__name__)
app.session_interface = RedisSessionInterface(redis=redis_pool.single_pool, key_prefix="yoyo")

@student.route(‘/student/<regex("\d+"):nid>‘)
def list_student(nid):
    session[‘username‘] = ‘aike‘
    return render_template("student.html")

方式二：

import redis

pool = redis.ConnectionPool(host="10.0.0.10", password="azn950626", port=6379)
single_pool = redis.Redis(connection_pool=pool)

redis_pool.py

from .utils import regex, redis_pool
from flask.ext.session import Session


app.config[‘SESSION_TYPE‘] = ‘redis‘
app.config[‘SESSION_REDIS‘] = redis_pool.single_pool
Session(app)

问题1：如何关闭浏览器，cookie则失效： permanent=False

app.session_interface = RedisSessionInterface(redis=redis_pool.single_pool, key_prefix="yoyo"， permanent=False)

问题2：cookie默认超时时间是多久？如何设置超时时间

　　　　默认31天，在默认配置文件中修改

app = Flask(__name__)
    app.default_config

"PERMANENT_SESSION_LIFETIME": timedelta(days=31),  # session在浏览器超时时间
