SignedURL authentication and PUT Method

[Droidment]

Hello,

I am using the SignedURL Authentication. I am able to get the list of contents in the bucket but unable to PUT to it. If I add the name of the new file to the canonical resource, for eg. /<Existing bucket>/<new file name> , I get a SignatureDoesnotMatch error. The canonical resource in the error message shows one /<Existing bucket>.

If I remove the file name and try to add the file anyway, I get a MalformedBucketConfiguration. 

The documentation for SignedUrl Authentication doesnot indicate PUT method is supported. Is it not?

Thanks

Hi Droidment

I'm a GCS newbie myself, but from what I have understood Signed Urls is only for "GET" ( Signed URLs (Query String Authentication) ). Other HTTP verbs are not supported in Signed URL. Proof is: when you get the error message XML from GCS in browser, try to view-source. It will give you the full explanation of what it is actually expecting. I have noticed that GCS always expects GET verb, no matter which verb we send. I tried DELETE, PUT with no luck.

what you want to do is actually "semi" documented here:  PUT Object . However I have not been able to figure out how to create " Authorization " header in this process. I've an open question pending in this forum. I hope we will hear from GCS team soon.

Hi Droidment,

This is definitely supported, so it sounds like you might be having trouble constructing the string to sign. If you're willing to share some code (either here or to gs-...@google.com), one of us can take a look.

Shrek: I'm answering your question in the thread that you started.

Thanks,

Appreciate your quick reply, Navneet. I have sent the code to gs-team mail account.
