uts 遵守协议无效，要怎么处理

uts 写iOS端http请求使用URLSessionDelegate 复写的协议方法不生效，这个要怎么办？

class MySessionDelegate implements URLSessionDelegate {  
    urlSession(_ : URLSession, @argumentLabel("didReceive") challenge : URLAuthenticationChallenge, completionHandler : (disposition ?: URLSession.AuthChallengeDisposition, credential ?: URLCredential) => void) {  
        console.log("challenge-->", challenge);  
        if (challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust) {  
            completionHandler(URLSession.AuthChallengeDisposition.useCredential, URLCredential(trust = challenge.protectionSpace.serverTrust!))  
        } else {  
            completionHandler(URLSession.AuthChallengeDisposition.performDefaultHandling, null)  
        }  
    }  
}  

export const hkRequest : MyApi = function (params : MyApiOptions) {  
    const options : MyApiOptionsType = params.options  
    console.log("options-->", options);  
    const url = new URL(string = options.url)!  
    const request : URLRequest = new URLRequest(url = url)  
    request.httpMethod = options.method  
    if (options.method != 'GET') {  
        try {  
            request.httpBody = UTSiOS.try(JSONSerialization.data(withJSONObject = options.data, options = []))  
        } catch (e) {  
            //TODO handle the exception  
            params.fail?.(e)  
            return  
        }  
    }  
    request.setValue("application/json", forHTTPHeaderField = "Content-Type")  
    const session = new URLSession(configuration = URLSessionConfiguration.default, delegate = new MySessionDelegate(), delegateQueue = null)  
    try {  
        const task = session.dataTask(with = request, completionHandler = (data ?: Data, response ?: URLResponse, error ?: any) => {  
            console.log("response--->", response);  
            console.log("data-->", data);  
            console.log("error-->", JSON.stringify(error));  
            if (response == null) {  
                params.fail?.('请求异常')  
                return  
            }  
            params.complete?.(response)  
            if (error != null && data != null) {  
                params.fail?.(error)  
                return  
            }  
            console.log("data-->", data);  
            try {  
                const result = UTSiOS.try(JSONSerialization.jsonObject(with = data!))  
                params.success?.(result)  
            } catch (e) {  
                //TODO handle the exception  
                params.fail?.(e)  
                return  
            }  

        })  
        // 启动请求  
        task.resume()  
    } catch (e) {  
        //TODO handle the exception  
        console.log("e--->", e);  
    }
