How to get the request token during OAuth dance when invoking OSLC from DOORS with Lyo Eclipse?

1
Marianna Budnikova (26●1●1●3) | asked Jul 03 '13, 10:15 a.m.
Hi! 

I am trying to invoke an OSLC service from DOORS with Lyo Eclipse SDK, and I am having a problem with OAuth dance. 

When I am trying to get the response token, I receive a HTTP 401 Unauthorized (Invalid signature for signature method HMAC-SHA1). Here is the GET HTTP being sent:

GET /dwa/oauth-request-token?oauth_consumer_key=ed69becd-cff7-4971-8968-cd4365d31fc6&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1372858221&oauth_nonce=91641252155718&oauth_version=1.0&oauth_signature=tneemmQNiDo8HN+l4gqjkkmwtv8=

I am using DOORS Web Access 1.5.0.0 (Build 214).

Any help or comments are greatly appreciated!

Thanks,
Marianna

Which Doors version are you using ( not DWA version )  ?

Also, I have a a version of that sample that works with previous versions of doors ( I think 9.4 ) ? I could send you via email if needed.

Just checked, I have the version 9.4. Will you please send me the sample that works with this version to marianchik<at>list<dot>ru ? Thank you!

Sorry for a late update, but I changed the code of DoorsOauthSample.java to an older version, and I was able to login. Apparently, DOOR 9.4 does not work with the new version of DOORS sample in Lyo. I changed in function validateTokens by replacing the following code:


HttpPost formPost2 = new HttpPost(location.getValue());
formPost2.addHeader("Content-Type","application/x-www-form-urlencoded;charset=UTF-8");

HttpParams params = new BasicHttpParams();
params.setParameter("oauth_token", oauthToken);
params.setParameter("oauth_verifier", oauthverifier);
params.setParameter("authorize", "true");
formPost2.setParams(params);

 with this code:


HttpPost formPost2 = new HttpPost(authURL);
formPost2.getParams().setParameter("oauth_token", oauthToken);
formPost2.getParams().setParameter("oauth_verifier", oauthverifier);
formPost2.getParams().setParameter("authorize", "true");
formPost2.addHeader("Content-Type","application/x-www-form-urlencoded;charset=UTF-8");

Have you checked the DoorsOauthSample.java in package org.eclipse.lyo.client.oslc.samples ? That sample works fine for latest versions of Doors.

 Gabriel, I tried running the sample you suggested, and it gets the same HTTP 401 error.

I think you need to UrlEncode the oauth_signature, (checked with my version)
also maybe thats because of the accept header, but I am not sure
