Flask -如何使用装饰器从app.before_request排除路由？

from flask import Flask, request

app = Flask(__name__)

# 定义一个装饰器函数，用于排除指定路由
def exclude_route(route):
    def decorator(func):
        func._exclude_route = route
        return func
    return decorator

# 在before_request钩子函数中检查路由是否需要排除
@app.before_request
def before_request():
    excluded_routes = [func._exclude_route for func in app.view_functions.values() if hasattr(func, '_exclude_route')]
    if request.endpoint in excluded_routes:
        return

# 使用装饰器来排除指定路由
@app.route('/')
def index():
    return 'Hello, World!'

@app.route('/admin')
@exclude_route('/admin')
def admin():
    return 'Admin Page'

if __name__ == '__main__':
    app.run()
