如何在swift中为alamofire请求编写通用包装器？

import Alamofire

class APIManager {
    static let shared = APIManager()
    
    func sendRequest(url: String, method: HTTPMethod, parameters: Parameters?, headers: HTTPHeaders?, completion: @escaping (Result<Any, Error>) -> Void) {
        AF.request(url, method: method, parameters: parameters, headers: headers)
            .validate()
            .responseJSON { response in
                switch response.result {
                case .success(let value):
                    completion(.success(value))
                case .failure(let error):
                    completion(.failure(error))
                }
            }
    }
}

// 使用通用包装器发送请求
let apiManager = APIManager.shared
apiManager.sendRequest(url: "https://api.example.com/users", method: .get, parameters: nil, headers: nil) { result in
    switch result {
    case .success(let response):
        // 处理成功响应
        print(response)
    case .failure(let error):
        // 处理错误
        print(error)
    }
}
