发布后未触发 dotnet 核心订阅者

如何解决发布后未触发 dotnet 核心订阅者

我正在 Dotnet 核心中开发 Redis(StackExchange.Redis) PUBSUB 系统，一切正常，直到我发布到我的频道。订阅者根本不会被触发。

这是我的代码：

program.cs

public static void Main(string[] args)
        {
            _ = runconsumer();
            BuildWebHost(args).Run();
        }

        private static async Task runconsumer()
        {
            LogWriter logger = new LogWriter();
            IEnvironment envProvider = new EnvironmentProvider();

            try
            {
                ICache cache = new Cache(envProvider);
                IDataRepository dataRepo = new DatabaseRepository();
                PubBusiness publisher = new PubBusiness();
                await publisher.ImportData();
            }
            catch (Exception ex)
            {
                await logger.WriteLogErrorAsync($"Exception occurred",ex);
                Environment.Exit(-1);
            }
        }

出版商

// ... code that creates my key

// add my data to a batch and save it to redis
batchTasks.Add(batch.ListRightPushAsync("jobs",key));
batch.Execute();
Task.WaitAll(batchTasks.ToArray());

// publishing
ISubscriber sub = _connection.GetSubscriber();
await sub.PublishAsync("uploaded",key);

订阅者

var db = _connection.GetDatabase();
ISubscriber sub = _connection.GetSubscriber();

// it will never pass here
            await sub.SubscribeAsync("uploaded",async (channel,value) =>
            {
                var key = (await db.ListLeftPopAsync("jobs")).ToString();
               // do my stuff here
            });
