推荐答案

您也可以像 azure 门户那样发送请求.来自 AZ 门户的所有 C2D 都通过此端点发送 https://main.iothub.ext.azure.com/api/Service/SendMessage/ 并且有效负载是一个如下所示的 json:

You could also send the request as the azure portal does it. All C2D from AZ Portal are sent through this Endpoint https://main.iothub.ext.azure.com/api/Service/SendMessage/ and the payload is a json that look like this:

{
  "hostName": "iothub-hostname",
  "owner": "twinUpdate",
  "key": "key for the iothub",
  "deviceID": "your device on that hub",
  "body": "{\"test\": \"This is a test over postman\"}",
  "properties": "[]"
}

请记住，您需要添加具有有效承载令牌的授权标头.您可以在登录 AZ Portal 时获得此信息.

Keep in mind that you need to add an Authorization Header with valid Bearer token. You can get this when you log in to AZ Portal.
