Microsoft Azure IoT Hub：将消息从base64格式解码到消息路由中的8-UTF查询
我有一个将传感器数据发送到Iot-Hub的设备。我从设备中获得的消息是用Base64格式编码的。我无法在设备的设置中更改它。因此，当我打开JSON数据时，“主体”值会被编码（无法读取），并且必须转换为UTF-8格式。我想知道是否可以在Iot Hub中的“消息路由查询”中编写代码，以便Microsoft Azure自动以格式化UTF-8转换接收的JSON数据以查看信号的值？
预先感谢

I have a device which sends sensor data to an IoT-hub. The messages that I get from the device are with base64 format encoded. I cannot change it in my device's settings. Thus, when I open the JSON data, the "body" values are encoded (cannot be read) and must be converted to the UTF-8 format. I would like to know whether it is possible to write a code in "message route query" in IoT Hub so that Microsoft azure automatically converts the received JSON data in format UTF-8 to see the values of the signals?
Thanks in advance

将消息发送为 utf-8 编码 JSON 正在对您的消息对象设置两个步骤。将以下代码添加到我的应用程序将解决问题。您可以参考此 github link 。

Sending the message as UTF-8 encoded JSON is setting two steps on your message object. Adding the following code to my application will solve the problem. You can refer this GitHub link .
