Ability to attach custom headers to S3 uploaded files

[Dusty Wilson]

Is there a way to PUT a file to S3 with some custom headers attached?  I need to set Content-Disposition and Access-Control-Allow-Origin for various files.  I notice that I could use S3.query() if it weren't private.  I just wanted to make sure that there wasn't something I was missing before I try to implement it myself.

Thanks!

I also need to set content-disposition.

Gustavo, would you accept a patch to

add support for custom headers?

How would you recommend going about

the implementation? How would you feel

if each of the Bucket methods (Put, Get,

Del, etc) returned a Request value rather

than actually running the operation? The

user could, optionally, add headers to the

request, then actually send it. So it'd be

something like this:

    err := b.NewPut(...).Do()

or, to set a header:

    r := b.NewPut(...)

    r.Header.Set("content-disposition", "...")

    err := r.Do()

Hey Keith,

Definitely. The only issue is that I'm not entirely sure about the
best approach around this yet. I've been thinking about this, and will
try to experiment with an interface to get a feeling for how it would
look like in practice.

Yeah, I know this is how the Google APIs are structure, but I honestly
don't find these interfaces very attractive. It feels a bit like
foo.DoIt(foo).NoIMeanit().

Maybe that's the best way to go, though. Please give me a moment and
I'll try to come up with something this week still.

Hey Guys,

I'd like to bump these ideas. I would like to supply custom headers, but i would also like to be able to change the request method.

Locally, I've changed the goamz/s3 project to make the Query() accessible from outside the package. I got the solution to work by exposing some extra types. I dislike hacking the code only for myself and I've tinkered with some alternatives to what I did, but think it would be good to talk options before I go too far. 

I could go for the GoogleAPI style if it were additional to the existing API. For example: NewRequest(...) (request Request). Then DoRequest(request)

Let me know if I can help or if this already got solved.

Thanks,
Walt

Hey,

I'd also like to bump this. It would be especially useful for specifying x-amz-server-side​-encryption​-customer-algorithm for server side encryption. Currently it dose not seem possible to upload with this value set.

Maybe just add a "additional headers" parameter to the s3 PUT methods?

Is this being worked on or has been been fixed yet?
