编写CherryPy装饰器以进行授权

import cherrypy

def authorize(username, password):
    # 在这里进行授权逻辑的实现，例如验证用户名和密码是否匹配
    if username == "admin" and password == "password":
        return True
    else:
        return False

def auth_required(func):
    def wrapper(*args, **kwargs):
        # 在这里进行授权检查
        username = cherrypy.request.headers.get("username")
        password = cherrypy.request.headers.get("password")
        if authorize(username, password):
            # 授权通过，执行原始函数
            return func(*args, **kwargs)
        else:
            # 授权失败，返回错误信息
            cherrypy.response.status = 401
            return "Unauthorized"
    return wrapper

class MyWebService:
    @cherrypy.expose
    @auth_required
    def index(self):
        return "Hello, world!"

if __name__ == "__main__":
    cherrypy.quickstart(MyWebService())
