FLASK学习记录-Flask视图之Cookie&Session

Cookie

　　Cookie是网站辨别用户身份，进行会话跟踪而存储在用户本地终端上的数据，由用户客户端计算机暂时或永久保存。

from flask import Flask, request, make_response
from datetime import datetime

app = Flask(__name__)

@app.route('/set_cookie')
def set_cookie():
    resp = make_response("create a cookie")
    resp.set_cookie("name1", "Anna")
    resp.set_cookie("name2", "Tom",expires=datetime(2024,3,28,16,30,00))
    resp.set_cookie("name3", "Bob", max_age=3600)
    resp.headers["Set-Cookie"] = "name4=Sam;Max-Age=300"
    return resp

@app.route('/get_cookie/<name>')
def get_cookie(name):
    cookie = request.cookies.get(name)
    return cookie

@app.route('/delete_cookie/<name>')
def delete_cookie(name):
    resp = make_response('delete_cookie success')
    resp.delete_cookie(name)
    return resp

if __name__ == '__main__':
    app.run(host='0.0.0.0',port=8000,debug=True)

http://xxx:8000/set_cookie/name1

http://xxx:8000/get_cookie/name3

http://xxx:8000/delete_cookie/name1

 Session

session是另一种记录客户状态的机制。区别在于cookie保存在客户端浏览器中，session保存在服务器上。

from flask import Flask, session
from datetime import timedelta
import os

app = Flask(__name__)
app.config['SECRET_KEY'] = os.urandom(12)
app.config['PERMANENT_SESSION_LIFETIME'] = timedelta(days=10)

@app.route('/set_session')
def set_session():
    session['name'] = 'Jack'  
    session.permanent = True
    return 'set session'

@app.route('/get_session')
def get_seesion():
    return session.get('name')

@app.route('/delete_session')
def delete():
    session.pop('name')
    return 'delete success'

@app.route('/clear_session')
def clear_session():
    session.clear
    return 'clear success'

if __name__ == '__main__':
    app.run(host='0.0.0.0',port=8000,debug=True)

http://xxxx:8000/set_session, http://xxxx:8000/get_session, http://xxxx:8000/delete_session, http://xxxx:8000/clear_session
