Flask中使用cookie和session

设置cookie

from flask import Flask,Response
app = Flask(__name__)
@app.route('/index')
def index():
    response = Response("设置cookie")
    response.set_cookie('username','sfencs')
    return response
if __name__ == '__main__':
    app.run()

获取cookie

username= request.cookies.get('username')

删除cookie

response.delete_cookie('username')

设置session

使用session需要设置SECRET_KEY

from flask import Flask,Response,session
app = Flask(__name__)
app.config['SECRET_KEY'] = ‘asdadasd’
@app.route('/index')
def index():
    session['username'] = 'sfencs'
    return 'session'
if __name__ == '__main__':
    app.run()

获取session

username = session.get('username')

删除session

 session.pop('username')
 session.clear()          #删除所有session
