Azure Iot SDK-上传Blob元数据吗? [英] Azure Iot sdk - upload blob metadata?

问题描述

Azure Iot集线器和sdk支持Blob上传非常好.但是，似乎不存在Blob元数据上传.有计划添加功能吗?对于小型项目来说，这是非常方便的功能.

It's great that Azure Iot hub and sdk supports blob uploading. However it seems blob metadata uploading is not there. Any plan to add the feature? It's a very handy feature for small projects.

还是已经支持，但是我错过了什么?

Or it's already supported but I missed something?

第2步:上传Blob和元数据

Step 2: Upload blob and metadata

第3步:完成设备上传过程:

Step3: Complete the device uploading process:
