flask-session

通过引入第三方模块flask-session来将session信息保存到数据库中

flask-session的简单应用

from flask_session import Session,RedisSessionInterface
from flask import Flask,session
import redis

from redis import Redis


app = Flask(__name__)
# 第一种连接数据库方法
conn=redis.Redis(host='127.0.0.1',port=6379)
app.session_interface=RedisSessionInterface(conn,key_prefix='flask_')

# 第二种方法
# app.config['SESSION_TYPE'] = 'redis'
# app.config['SESSION_REDIS'] = Redis(host='127.0.0.1',port='6379')
Session(app)

@app.route('/')
def enter():
    session['name'] = 'zjh'
    return 'hello'

@app.route('/get_name')
def get_name():
    res = session.get('name')
    print(res)
    return 'get_name'

if __name__ == '__main__':
    app.run()
