To Access Cookies
To access the cookie, we use the cookie attribute of the request object. A dictionary-like attribute that contains all the cookies sent by the browser is known as the cookie attribute. Open main2.py and modify the cookie() view function as follows:
@app.route('/cookie/')
def cookie():
if not request.cookies.get('spark'):
res = make_response("Setting a cookie")
res.set_cookie('spark', 'bar', max_age=60*60*24*365*2)
else:
res = make_response("Value of spark is {}".format(request.cookies.get('spark')))
return res
We have to modify our view function to display the cookie value assuming there is a cookie. Otherwise, it will set a cookie for us.
