Question

我已经搜索了很多，我正在尝试使用python和azure事件sdk将接收器连接到我的azure上的aot上的iot集线器，但是遗憾的是没有成功，我的接收者告诉我它已经与客户端建立了连接，但是它从未真正查看过数据

您拥有的代码可以正常工作，但是您需要检查以下几点：

如果您使用的是IoT Hub内置事件端点，请确保您使用的是来自Event Hub兼容端点的名称空间名称，以及该名称的Event Hub兼容名称。我测试过的地址如下：amqps://ihsuprodbyresXXXXXXnamespace.servicebus.windows.net/iothub-ehub-sample-XXXXX-XXXXXXXXXX
- 请确保您使用的是iothubowner键值。
- 确保您正在使用的使用者组已添加到与事件中心兼容的端点。
- 默认情况下，与事件中心兼容的终结点具有两个分区-您的代码仅侦听其中一个分区上的消息。
