Streamlit：捕获用户会话并重新加载应用程序

Question

我正在使用 Streamlit 创建一个简单的应用程序。应用程序有一个用户登录表单，使用Firebase 对用户进行身份验证。身份验证后我希望存储用户信息并重新加载应用程序。我可以使用以下代码实现此目的，但问题是每次我手动刷新页面时，我都会再次获得登录页面。有没有办法在手动刷新后存储用户值？

import streamlit as st
import pyrebase


#Config Key
firebaseConfig = {
    'apiKey': "xxxxxxxx",
    'authDomain': "xxxxxxx",
    'projectId': "xxxx",
    'databaseURL': "xxxxxx",
    'storageBucket': "xxxxxxx",
    'messagingSenderId': "xxxxxxxx",
    'appId': "xxxxxxxxxxx",
    'measurementId': "xxxxxxxx"
}

# Firebase Authentication
firebase = pyrebase.initialize_app(firebaseConfig)
auth = firebase.auth()

# Database
db = firebase.database()
storage = firebase.storage()


login = None

if 'cached_token' not in st.session_state:
    with st.form("user_login_form"):
        email = st.text_input('Please enter your email address')
        password = st.text_input('Please enter your password',type = 'password')
        
        # Every form must have a submit button.
        submitted = st.form_submit_button("Submit")
        if submitted:
            user = auth.sign_in_with_email_and_password(email,password)
            st.write("submitted",user['email'])
            st.session_state["cached_token"] = "submitted",user['email']
            st.write(st.session_state["cached_token"])
            st.experimental_rerun()
else:
    st.write('Welcome!')
    st.write(st.session_state["cached_token"])
