Maybe doesn't work?

[JamesDConley]

Maybe I am misunderstanding how to use this- but I am unable to get cookies to persist on my browser

I put this at the start of my streamlit app

controller = CookieController()
user_id = controller.get('user_id')
if user_id is None:
    controller.set("user_id", str(uuid4()))
user_id = controller.get('user_id')

And I am getting new UUIDs each time I refresh the page. Seems like the cookies are getting cleared on refresh ( I get new UUIDs each time I refresh )

I've tried setting some different settings, most recently same_site="lax", secure=False, partitioned=True, max_age=999999999999999 but I always get the same result (different UUIDS on refresh)

Same here. I got the following test code from Streamlit Forum but getAll() is misleading since it doesn't fetch cookies from browser (just buffered return). Then I tried with a refresh (see after) but raises streamlit.errors.DuplicateWidgetID: There are multiple widgets with the same key='cookies'

controller = CookieController()

# Set a cookie
controller.set('cookie_name', 'testing')

# Get all cookies
# controller.refresh()
cookies = controller.getAll()

# Get a cookie
cookie = controller.get('cookie_name')

# Remove a cookie
controller.remove('cookie_name')

Nota: while running under debugger, the cookie appeared once in the browser... but not repeatable.

For me, it seem neither the getAll() nor get() picked up any thing from cookie. It's weird .

I'm also seeing very weird behavior (especially with multipage app). During logout, I do

token_expiry(email)
if controller.get('c_user'):
    controller.remove('c_user')
st.info("Logged out successfully!")
st.switch_page("Home.py")

And below is a repeated error I see even when I explicitly set the key (controller.set('c_user', email))

  File "/usr/local/lib/python3.12/site-packages/streamlit_cookies_controller/cookie_controller.py", line 163, in remove
    self.__cookies.pop(name)
KeyError: 'c_user'

There are multiple other cases noted as well where this doesn't seem to work consistently. Sometimes getAll() doesn't even print anything. What is equally weird is when I print

st.write(st.session_state.get('cookies'))

prints cookies with c_user (key) But when I print below, both donot return anything.

st.write(controller.getAll())
st.write(controller.get('c_user'))

I'm also having problems getting a cookie.

    if st.button("登录"):
        if username and password:
            # 简单验证（例如，用户名和密码是否都不为空）
            controller.set('username', username)
            st.experimental_rerun()

# 主逻辑
if check_login():
    welcome_user()
    if st.button("注销"):
        controller.remove('username')
        st.experimental_rerun()
else:
    login_form()
