Authentication Failure while trying to add Target using objective C

By MohitTrivedi on Fri, 03/22/2013 - 06:46

Hi,

I am trying to add the image Target using VWS.I am using objective C for this.

I am having some problem and getting Authentication Failure response from server.

I have some String printed on Console.I want to ask whether these strings are valid or not

1) "StringToSign" in Signature finding

I am getting output of this string like:

HTTP-Verb: POST

Content-MD5: ad7dcb3160992a01fade8c517b9977ce

Content-Type: application/json

Date: Fri, 22 Mar 2013 06:10:09 GMT

Request-Path: /targets

And Signature String is:

Z9BCioSnemneazKeIuVK40X+4z8AJBBdQnzoXF7y514=

I want to ask whether Content-MD5 string is valid?or any problem in Signature String?

Please help me to solve this issue.

I am also facing the same problem

While it is theoretically possible to access the VWS API from a device, it is not the recommended way.

I have resolved the problem already.

Thanks for your reply.

Are you able to share your resolution?

Am struggling with the same problem, getting an authentication error.

I translated the "SignatureBuilder.php" file to objective c best i could..although obviously not good enough.

Thanks
