我正在尝试在我的应用程序摘要auth中实现，但我正在努力，或者工作不正常

我已按照您在

AuthenticationTestCase

中的描述设置了我的请求，代码如下：

let userName = "***********"
let password = "***********"
let qop = "auth"
let xmlStr: String = "<?xml version=\"1.0\" encoding=\"utf-8\"?><methodCall><methodName>authenticate.login</methodName></methodCall>"
let postData:Data = xmlStr.data(using:  String.Encoding.utf8, allowLossyConversion: true)!
let url = URL(string: "https://app.**********.co.uk/service/mobile/digest-auth/\(qop)/\(userName)/\(password)")
var request = URLRequest(url: url!)
request.httpShouldHandleCookies = true 
request.setValue("\(String(describing: xmlStr))", forHTTPHeaderField: "Content-Length")
request.setValue("application/xml", forHTTPHeaderField: "Content-Type")
request.setValue("IOS133928234892nil", forHTTPHeaderField: "User-Agent")
request.setValue("application/xml", forHTTPHeaderField: "Accept")
request.httpMethod = "POST"
request.httpBody = postData 
     AF.request(request)
         .authenticate(username: userName, password: password)
         .response { response in ........

注意：如果我通过邮递员发出同样的请求，它会正常工作。 看起来Alamofire没有正确处理摘要挑战

你能帮我解决这个问题吗
