为streamlit提供登录界面

准备工作

pip install streamlit-authenticator

创建 YAML 文件：config.yaml

credentials:
  usernames:
    liba001:
      email: jsmith@gmail.com
      name: John Smith
      password: abc # To be replaced with hashed password
    liba002:
      email: rbriggs@gmail.com
      name: Rebecca Briggs
      password: def # To be replaced with hashed password
cookie:
  expiry_days: 365
  key: random_signature_key # Must be string
  name: random_cookie_name
preauthorized:
  emails:
  - melsby@gmail.com

使用 Hasher 模块将纯文本密码转换为哈希密码：

import streamlit_authenticator as stauth
hashed_passwords = stauth.Hasher(['abc', 'def']).generate()
print(hashed_passwords)

将 YAML 文件中的纯文本密码替换为生成的哈希密码

开始主程序

import yaml
from yaml.loader import SafeLoader
with open('config.yaml') as file:
    config = yaml.load(file, Loader=SafeLoader)

authenticator = Authenticate(
    config['credentials'],
    config['cookie']['name'],
    config['cookie']['key'],
    config['cookie']['expiry_days'],
    config['preauthorized']
)
name, authentication_status, username = authenticator.login('Login', 'main')

if authentication_status:
    authenticator.logout('Logout', 'main')
    st.write(f'Welcome *{name}*')
    st.title('Some content')
elif authentication_status == False:
    st.error('Username/password is incorrect')
elif authentication_status == None:
    st.warning('Please enter your username and password')
