Swift 4-Alamofire-认证NTLM使用无效凭据

Question

我有一个问题与身份验证NTLM credenitals，当我使用有效的凭据，它的作品，但当我使用无效的凭据它不会失败，它的作品一样，因为它会与有效的凭据。只有当我首先输入有效凭据时才会出现这种情况。有没有办法清除凭据，或者我在这里做错了什么？这是我的代码：

func loginUser(_ username: String, password: String, completion: @escaping (_ result: Bool) -> Void)
    {

        let user = username

        let password = password

        let url = webservice

        let credential = URLCredential(user: user, password: password, persistence: .none)

        let headers = ["Accept": "application/json;odata=verbose", "Content-type": "application/json;odata=verbose"]

        Alamofire.request(url, method: .get, headers: headers).authenticate(usingCredential: credential).responseJSON {
                (response) in

                print(response.result)

                switch response.result {

                case .success:
                    if let value = response.result.value {

                        completion(true)

                    }else{

                        print("There is error in the server response")

                        completion(false)
                    }

                case .failure (let error):

                    print("The NTLM request error is: ", error.localizedDescription)

                    completion(false)

                }

            }

    }

我注意到一件事，如果我输入有效的文件夹，然后等待几分钟，输入无效的文件，它会像预期的那样工作。

更新

我已经更新了我的代码，这样：

func loginUser(_ username: String, password: String, completion: @escaping (_ result: Bool) -> Void)
    {

        let user = username

        let password = password

        let url = webservice

        let credential = URLCredential(user: user, password: password, persistence: .none)

        var urlRequest = URLRequest(url: URL(string: url)!)

        urlRequest.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData

        urlRequest.httpMethod = "get"

        urlRequest.setValue("application/json;odata=verbose", forHTTPHeaderField: "Content-type")

        urlRequest.setValue("application/json;odata=verbose", forHTTPHeaderField: "Accept")

        Alamofire.request(urlRequest).authenticate(usingCredential: credential).responseJSON {
                (response) in

                switch response.result {

                case .success:
                    if let value = response.result.value {


                       completion(true)

                    }else{

                        print("There is error in the server response")

                        completion(false)
                    }

                case .failure (let error):

                    print("The NTLM request error is: ", error.localizedDescription)

                    completion(false)

                }

            }

    }

添加缓存策略，但仍然得到相同的结果：(

不返回HTTP错误的失败。您需要查看HTTP响应中的。成功案例中的响应代码，该代码指示授权失败。

请看这里：Swift-Alamofire：如何获取HTTP响应状态代码，以便执行此操作。

或者你可能会碰到缓存。请参阅：如何在Alamofire中禁用缓存
