异常函数的写法：

        public static  Task<string> HttpGetAsync(string url, Dictionary<string, string> headers = null)
        {
            try
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                if (headers != null)
                {
                    foreach (var header in headers)
                        request.Headers[header.Key] = header.Value;
                }
                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    Stream responseStream = response.GetResponseStream();
                    StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8);
                    return streamReader.ReadToEndAsync();
                }
            }
            catch (Exception ex)
            {
                return Task.FromResult(ex.Message);
