使用适用于 .NET 的 Firebase 云消息传递 API 客户端库发送推送通知

Question

我正在开发 .NET Web API，我想将推送通知发送到我的 Android 应用程序。我已经配置了 Firebase，并且能够使用旧版 REST API 客户端发送到主题“foo-bar”。我现在想发送图像，我认为旧版 REST API 不再支持这些图像。

我已经创建了一个控制台应用程序并引用了 Google.Apis.FirebaseCloudMessaging.v1，但是关于如何正确使用它的文档似乎很少。

I have created the following code, based on what I could glean at the Github repository (https://github.com/googleapis/google-api-dotnet-client/blob/main/Src/Generated/Google.Apis.FirebaseCloudMessaging.v1/Google.Apis.FirebaseCloudMessaging.v1.cs) 

static async Task PostMethod2()
        {
            BaseClientService.Initializer initializer = new BaseClientService.Initializer()
            {
                ApiKey = "<MY_API_KEY>",
                ApplicationName = "<MY_PROJECT_NAME>"
            };

            FirebaseCloudMessagingService service = new FirebaseCloudMessagingService(initializer);

            ProjectsResource PR = new ProjectsResource(service);
            SendMessageRequest SMR = new SendMessageRequest()
            {
                Message = new Message()
                {
                    Topic = "foo-bar",
                    Notification = new Notification()
                    {
                        Title = "Sparky Says Hello!"
                    },
                    Android = new AndroidConfig()
                    {
                        Notification = new AndroidNotification()
                        {
                            Image = "<My Image URL>"
                        }
                    },
                    Apns = new ApnsConfig(),
                    Webpush = new WebpushConfig()
                }
            };

            SMR.Message.Apns.Payload = new Dictionary<string, object>();
            SMR.Message.Apns.Payload.Add("mutable-content", 1);
            SMR.Message.Webpush.Headers = new Dictionary<string, string>();
            SMR.Message.Webpush.Headers.Add("image", "<My Image URL>");
            SendRequest SR = PR.Messages.Send(SMR, "projects/<My Project ID>");
            Console.WriteLine("Got Here");
        }

The debugger goes through each of the lines OK, but no notification appears. I have no visibility on the return result. Can someone please assist? Thank you.

您需要执行发送吗？

var response = SR.Execute();
