通过azure-sdk-for-go下载Azure函数文件

I'm trying to find a way to download Azure function files through azure-sdk-for-go. Basically something similar to theirs portal. Will appreciate any help.

The way to do it is to use Azure Kudu API. Each Azure function App have a publish profile which can be fetched from the SDK or the site itself. From the publish profile we get a (key, secret) pair to use in the Kudu zip api
