невозможно подключиться к концентратору событий Azure из сети Corpnet

Question

Я работаю в Azure Event Hub. У меня проблема при подключении к концентратору событий Azure, когда я подключен к сети Corpnet. Если я запускаю код без подключения к сети Corpnet, он работает нормально. Тест Telnet для концентратора событий выглядит хорошо, когда я подключен к сети Corpnet.

Есть идеи, как решить эту проблему?

Код

            public async Task SendDataAsync(CoffeeMachineData data)
            {
                EventData eventData = CreateEventData(data);
                await _eventHubClient.SendAsync(eventData);
            }



            private static EventData CreateEventData(CoffeeMachineData data)
            {
                var dataAsJson = JsonConvert.SerializeObject(data);
                var eventData = new EventData(Encoding.UTF8.GetBytes(dataAsJson));
                return eventData;
            }

Answer 1

Мы нашли решение для этого.При создании строки подключения концентратора событий пришлось использовать AmqpWebSockets.

        var connectionStringBuilder = new EventHubsConnectionStringBuilder(eventHubConnectionString)
        {
            EntityPath = entityName,
            TransportType = TransportType.AmqpWebSockets
        };

Answer 2

Есть идеи, как решить эту проблему?

пожалуйста, попробуйте установить для ConnectivityMode значение https (порт 443)

ServiceBusEnvironment.SystemConnectivity.Mode = ConnectivityMode.Https 

Похоже, это ограничение брандмауэра, которое блокирует весь трафик на портах 5671 и 5672 . Порт TCP по умолчанию используется для транспортных операций.

Мы могли бы получить больше информации от AMQP 1.0 в Руководство по протоколу Azure Service Bus и концентраторов событий .

Если возможно, вы можете попробовать открыть порт 5671 и 5672 .
