flask中cookie和session的使用

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
