Upload file with custom content type?

[shkim]

How can I set the content type of the uploading file? (for example, image/jpeg)
I tried to set the .ContentType member of returned value from obj.Attrs()
but it seems that Attrs() is only usable for download of existing file.
I found that there is UploadFile method but I could not find how to use.

It looks like you want the WithAttrsOption

I believe you'd need to do:

import "github.com/kurin/blazer/b2"

// ... all your setup code

w := bucket.Object(dst).NewWriter(ctx, b2.WithAttrsOption(&b2.Attrs{ContentType: "image/jpeg"}))

w.Write(myFileBlob)

see https://pkg.go.dev/github.com/kurin/blazer/b2#Attrs for the fields which can be set on upload in this way.
