How to route message to Service bus queue using routing query?

问题

I have an IoT hub with connected devices which sends telemetry messages. I want to read messages from each device separately, so I decided to create a different endpoint for each device. For sorting messages I use routes with query, but when I add a query rule to the route, messages stop going to the endpoint. Connected device uses MQTT.

Screenshots are below:

• Endpoint
• Routes
• toMyEndpoint route

回答1:

Your query expression is correct.

But make sure you set content type and content encoding like this:

Message eventMessage = new Message(Encoding.UTF8.GetBytes("{\"boarded\":\"0\"}"));
eventMessage.ContentType = "application/json";
eventMessage.ContentEncoding = "utf-8";

It works for me.

回答2:

try to send a D2C message on the following topic:

devices/{yourDeviceId}/messages/events/$.ct=application%2Fjson&$.ce=utf-8

Note, that the content-encoding is utf-8.
