在Bokeh项目中实现用户认证和权限管理可以通过以下步骤:
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>
通过以上步骤,您可以在Bokeh项目中实现用户认证和权限管理。您还可以根据项目需求和规模进一步扩展和定制认证和权限管理功能。
