如何使用路由查询将消息路由到服务总线队列?
问题描述：
我有一个IoT中心，该中心具有连接的设备，可以发送遥测消息.我想分别从每个设备读取消息，因此我决定为每个设备创建一个不同的终结点.为了对消息进行排序，我将路由与查询一起使用，但是当我向路由添加查询规则时，消息将停止到达端点.连接的设备使用MQTT.
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.
以下是屏幕截图:
- Endpoint
- Routes
- toMyEndpoint route
答
您的查询表达式正确.
但是请确保您按如下所示设置内容类型和内容编码:
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";
对我有用.
