    {


        private readonly IHttpClientFactory _clientFactory;
        string key = "key=llllll ......";
        string webAPIKey = "......";
        string Id = "......";

        public AppService(IHttpClientFactory clientFactory) {
            _clientFactory = clientFactory;
           
        }

public async Task<string> sendBroadCastNotification()
        {
            Data _data = new Data();
            _data.title = "test data Ttile";
            _data.detail = "test data detail";
            Notification _notification = new Notification();
            _notification.title = "test notification Ttile";
            _notification.body = "test notification body";

            MyNotification NotifcationData = new MyNotification {
            data=_data,
            notification=_notification,
            to= "/topics/all"
            };

            try {
           

            var client = _clientFactory.CreateClient();

               

            client.DefaultRequestHeaders.Add("project_id", Id );
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", key);


                StringContent bodyOfRequest = new StringContent(System.Text.Json.JsonSerializer.Serialize(NotifcationData ), Encoding.UTF8, "application/json");

            using var httpResponse =
          await client.PostAsync("https://.......", bodyOfRequest);

                var result = httpResponse.Content.ReadAsStringAsync().Result;

                return result;
            }
            catch (Exception ex)
            {
                throw new System.ArgumentException(ex.Message.ToString(), "original");

            }
            //return null;

        }

我在此链接中找到了答案：

client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", key);

我尝试添加授权标头的以下方式无法理解为授权标头：

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", key);
