Flask-Session

redis

import os
from flask import Flask, session, request
from flask_session import Session
from redis import Redis app = Flask(__name__)
app.config['SESSION_TYPE'] = 'redis' #session存储格式为redis
app.config['SESSION_REDIS'] = Redis( #redis的服务器参数
host='192.168.1.3', #服务器地址
port=6379) #服务器端口 app.config['SESSION_USE_SIGNER'] = True #是否强制加盐,混淆session
app.config['SECRET_KEY'] = os.urandom(24) #如果加盐,那么必须设置的安全码,盐
app.config['SESSION_PERMANENT'] = False #sessons是否长期有效,false,则关闭浏览器,session失效
app.config['PERMANENT_SESSION_LIFETIME'] = 3600 #session长期有效,则设定session生命周期,整数秒,默认大概不到3小时。
Session(app) @app.route('/')
def default():
return session.get('key', 'not set') @app.route('/test/')
def test():
session['key'] = 'test'
return 'ok' @app.route('/set/')
def set():
arg = request.args.get('key')
print(arg)
session['key'] = arg
return 'ok' @app.route('/get/')
def get():
return session.get('key', 'not set') @app.route('/pop/')
def pop():
session.pop('key')
return session.get('key', 'not set') @app.route('/clear/')
def clear():
session.clear()
return session.get('key', 'not set') if __name__ == "__main__":
app.run(debug=True)

本例通过flask-session扩展,实现了把session存储在redis服务器中。
