Flask setting cookies
0
I try to set cookies in Flask, but I don't get what I want to. Instead of getting username I get an respone attached to my URL.
My routes.py
@app.route('/login', methods=['GET', 'POST'])
def login():
if current_user.is_authenticated:
return redirect(url_for('index'))
form = LoginForm()
if form.validate_on_submit():
user = User.query.filter_by(username=form.username.data).first()
if user is None or not user.check_password(form.password.data):
flash('Invalid username or password')
return redirect(url_for('login'))
login_user(user, remember=form.remember_me.data)
userCookie = request.form['username']
resp = make_response(render_template('index.html'))
resp.set_cookie('user', userCookie)
next_page = request.args.get('next')
if not next_page or url_parse(next_page).netloc != '':
next_page = url_for('index', resp=resp)
return redirect(next_page)
return render_template('login.html', title='Sign In', form=form)
And I want to display the content of cooki in index.html
{% for r in resp %}
{{ r }}
{% endfor %}
Instead I get:
index?resp<Response+1250+bytes+[200+OK]>
What am I doing wrong?
[EDIT - logout method]
That's my method before adding cookies
@app.route('/logout')
def logout():
logout_user()
return redirect(url_for('index'))
So if I added cookies:
@app.route('/logout')
def logout():
resp = make_response(redirect('/login'))
resp.delete_cookie('user')
And if I rester server, login, the cookie is created, but after logout I can even go to the endpoint /login
return resp
python cookies flask

Ok, it works fine to some extend. If i login in to website, the cookie and session is created. The cookie has value of my user. But after logout, the cookie is removed and I can login in again. I can even display my login form

You need to return resp directly, make_response Convert the return value from a view function to an instance of response_class.
userCookie = request.form['username']
resp = make_response(render_template('index.html'))
resp.set_cookie('user', userCookie)
next_page = request.args.get('next')
if not next_page or url_parse(next_page).netloc != '':
return resp
In the html, get the cookie by javascript
<label id="label_id1"></label>
<script type="text/javascript">
alert(document.cookie);
document.getElementById('label_id1').innerhtml = document.cookie
</script>

Ok, it works fine to some extend. If i login in to website, the cookie and session is created. The cookie has value of my user. But after logout, the cookie is removed and I can login in again. I can even display my login form

I assume the problem is now in logout functionality. Can you update the question including the logout snippet?

You need to return resp directly, make_response Convert the return value from a view function to an instance of response_class.
userCookie = request.form['username']
resp = make_response(render_template('index.html'))
resp.set_cookie('user', userCookie)
next_page = request.args.get('next')
if not next_page or url_parse(next_page).netloc != '':
return resp
In the html, get the cookie by javascript
<label id="label_id1"></label>
<script type="text/javascript">
alert(document.cookie);
document.getElementById('label_id1').innerhtml = document.cookie
</script>
