我只是想使用 Azure IOT Hub 将我的设备连接到云。但我收到如下错误。
MessagingEntityNotFoundException:找不到消息传递实体“ihsuprodsgres029dednamespace:eventhub:iothub-ehub-”。TrackingId:4772b610-8ff3-4709-8ea9-ffcd5784fe1c_B4, SystemTracker:ihsuprodsgres029dednamespace:eventhub:iothub-ehub-sibeeshiot-176205-a588b66686~16383|team01, Timestamp:6/23/2017 3:07:54 PM TrackingId:41110b704d814af497fd9924da6714d8_G4, SystemTracker :gateway2,时间戳:2017 年 6 月 23 日下午 3:07:55,参考 ID:41110b704d814af497fd9924da6714d8_G4
如果您曾经遇到过同样的问题,请您帮我解决一下。下面是我正在尝试的代码。
static void Main(string[] args) {
Console.WriteLine("Receive messages. Ctrl-C to exit.\n");
eventHubClient = EventHubClient.CreateFromConnectionString(connectionString, iotHubD2cEndpoint);
var d2cPartitions = eventHubClient.GetRuntimeInformation().PartitionIds;
CancellationTokenSource cts = new CancellationTokenSource();
System.Console.CancelKeyPress += (s, e) = >{
e.Cancel = true;
cts.Cancel();
Console.WriteLine("Exiting...");
};
var tasks = new List < Task > ();
foreach(string partition in d2cPartitions) {
tasks.Add(ReceiveMessagesFromDeviceAsync(partition, cts.Token));
}
Task.WaitAll(tasks.ToArray());
}
private static async Task ReceiveMessagesFromDeviceAsync(string partition, CancellationToken ct) {
var eventHubReceiver = eventHubClient.GetConsumerGroup("Team01").CreateReceiver(partition, DateTime.UtcNow);
while (true) {
if (ct.IsCancellationRequested) break;
EventData eventData = await eventHubReceiver.ReceiveAsync();
if (eventData == null) continue;
string data = Encoding.UTF8.GetString(eventData.GetBytes());
Console.WriteLine("Message received. Partition: {0} Data: '{1}'", partition, data);
}
}
