Flask02 cookie和session

1. 写代码的时候遇到 url正确但not found的问题

解决方法： 更改端口号即可

if __name__ == '__main__':
    app.run(debug=True,port=3389)

2.app.py

from flask import Flask,Response,request,session

app = Flask(__name__)
# 'SECRET_KEY' 随便配置一串加密Key
app.config['SECRET_KEY'] = "12ASD34DS"

@app.route('/setcookie')
def setcookie():
    response = Response("cookie设置")
    response.set_cookie("user_id","xxx")
    return response

@app.route('/getcookie')
def getcookie():
    user_id = request.cookie.get("user_id")
    print("user_id:",user_id)
    return "获取cookies"

@app.route('/setsession')
def setsession():
    # 在flask中，session是在加密后存储到cookie中
    session['username'] = "nihao"
    return "session设置成功"

@app.route('/getsession')
def getsession():
    # 在flask中，session是在加密后存储到cookie中
    username = session.get('username')
    print("username:",username)
    return "getsession设置成功"

@app.route('/')
def hello_world():  # put application's code here
    return 'Hello World!'

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