关于cookie和session

@app.route(‘/login‘,methods=[‘GET‘,‘POST‘])
def login():

    print(request.method)
    if request.method == ‘GET‘:
        res = make_response(render_template(‘login.html‘,content=‘登录‘))
        return res
    else:
        # 这里可以在数据库匹配是否有此账号和密码。
        if request.form[‘username‘] == ‘admin‘ and request.form[‘password‘] == ‘admin‘:
            res_ = make_response(render_template(‘updatePage.html‘,text=‘成功登录准备跳转至首页‘))

            # 把cookie一起发送到后端
            today = datetime.datetime.today()
            endTime = today - datetime.timedelta(hours=8) + datetime.timedelta(seconds=30)

            res_.set_cookie(‘username‘,‘laowang‘,expires=endTime)

            # 把账号和密码一起携带过去。
            session[‘username‘] = request.form[‘username‘]
            session[‘password‘] = request.form[‘password‘]

            return res_
        else:
            print(‘做其他登录操作！‘)
