在Bokeh項目中實現用戶認證和權限管理可以通過以下步驟:
pip install Flask-Login
from flask_login import UserMixin
class User(UserMixin):
def __init__(self, id):
self.id = id
from flask import Flask, render_template, request, redirect, url_for
from flask_login import LoginManager, login_user, logout_user
app = Flask(__name__)
login_manager = LoginManager(app)
login_manager.login_view = 'login'
@login_manager.user_loader
def load_user(id):
return User(id)
@app.route('/login', methods=['GET', 'POST'])
def login():
if request.method == 'POST':
user_id = request.form['user_id']
user = User(user_id)
login_user(user)
return redirect(url_for('index'))
return render_template('login.html')
@app.route('/logout')
def logout():
logout_user()
return redirect(url_for('login'))
from flask_login import current_user, login_required
@app.route('/admin')
@login_required
def admin():
if current_user.id != 'admin':
return 'Permission denied'
return 'Welcome admin!'
<!-- login.html -->
<form method="post">
<input type="text" name="user_id" placeholder="User ID">
<input type="submit" value="Login">
</form>
通過以上步驟,您可以在Bokeh項目中實現用戶認證和權限管理。您還可以根據項目需求和規模進一步擴展和定制認證和權限管理功能。
