Summary
The package Extra-Streamlit-Components provides capacity for cookie management. However, due to Streamlitâs re-running mechanism, a lot of challenges were encountered while implementing read and write operations for cookies. Eventually, I managed to find the correct way to call these operations. Under the stateless protocol of HTTP, in the mechanism of Streamlit, stable read, judge and write operations of cookies can be carried out efficiently.
Steps to reproduce
Code snippet:
cookie_manager = get_manager()
start_time = time.time()
timeout = 0.01 # Preset timeout time
while True:
if 'cookies' not in st.session_state:
st.session_state['cookies'] = cookie_manager.get_all()
elif time.time() - start_time > timeout:
st.warning("Operation timeout. Please refresh the page or check your network connection.")
break # If timed out, exit the loop directly
else:
if 'lzs_userid' not in st.session_state.cookies:
if 'lzs_userid' not in st.session_state:
st.session_state["lzs_userid"] = str(uuid.uuid4())
cookie_manager.set('lzs_userid', st.session_state["lzs_userid"], key="0", expires_at=datetime.datetime(year=2023, month=8, day=2))
if "lzs_pwd" not in st.session_state.cookies:
if "lzs_pwd" not in st.session_state:
random_pwd = ''.join(random.choices(string.ascii_letters + string.digits,k=8))
st.session_state['lzs_pwd'] = bcrypt.hashpw(random_pwd.encode(),bcrypt.gensalt(rounds=10)).decode('utf-8')
cookie_manager.set('lzs_pwd', st.session_state.get('lzs_pwd', ''), key="1", expires_at=datetime.datetime(year=2023, month=8, day=2))
break
