上传Blob时可以设置访问层吗？ 如果是，那该怎么做？

Question

I did not find any way to set the access tier of a blob when I upload it, I know I can set a blob's access tier after I uploaded it, but I just want to know if I can upload the blob and set it's access tier in only one step. And if there is any golang API to do that?

I googled it but I got nothing helpful till now.

Here is what I did now, I mean upload it and then set it's access tier.

// Here's how to upload a blob.
blobURL := containerURL.NewBlockBlobURL(fileName)
ctx := context.Background()
_, err = azblob.UploadBufferToBlockBlob(ctx, data, blobURL, azblob.UploadToBlockBlobOptions{})
handleErrors(err)

//set tier
_, err = blobURL.SetTier(ctx, azblob.AccessTierCool, azblob.LeaseAccessConditions{})
handleErrors(err)

But I want to upload a blob and set it's tier in one step, not two steps as I do now.

The short answer is No. According to the offical REST API reference, the blob operation you want is that to do via two REST APIs Put Blob and Set Blob Tier. Actually, all SDK APIs for different languages are implemented by wrapping the related REST APIs.

Except for Page Blob, you can set the header x-ms-access-tier in your operation request to do your want, as below.

For Block Blob, the operations in two steps are necessary, and can not be merged.
