Unable to perform GET request on fileUrl from evidences API

[Sheetal Sulay]

Hi Team, 

I am using "https://jira.mydomain.com/rest/raven/1.0/api/testrun/1590644/attachment" from the API client and I am getting details of all attachments for this test run. I am also getting fileUrl in response in the below format

https://jira.mydomain.com/plugins/servlet/raven/attachment/36252/nameofevidence.jpg

Further, I want to perform "GET" on this URL to retrieve the actual file. But I am getting an authentication error. At the same time when I access the same URL in the browser, I am able to successfully download the attachment.

What I am missing here?
