Getting an Atom Feed from the feed URL (not the data URL) [Nov. 8th, 2004|11:50 am]
LiveJournal Client Discussions
Hello again,

I am working on accessing an LJ feed through the AtomAPI. I hope someone out there can help me out. I am sending the following request after discovering http://www.livejournal.com/interface/atomapi/username/feed from http://www.livejournal.com/users/username/data/atom from http://www.livejournal.com/users/username/. What this request should do is return the feed (after which I will retreive the service.post URL for posting).

GET http://www.livejournal.com/interface/atomapi/username/feed
Connection: close
Authorization: WSSE profile="UsernameToken"
User-Agent: Daily Blog Formatter (http://trevreport.org/blogForm.shtml)
Content-Length: 0
Content-Type: application/x.atom+xml
X-WSSE: UsernameToken Username="username", PasswordDigest="W9dSHn5BwJwQFHrD6tWr+JdBv4M=", Nonce="hhIbet0cbBsw9SQB1E/PG42U37s=", Created="2004-11-08T02:50:57Z"

There is nothing wrong with the Nonce, and the WSSE entry is well-formatted. In fact this request works perfectly in Blogger, but when I send the requst to LJ I get:

401 Authentication Failed

Digest authentication failed for this AtomAPI request.

You can try it out yourself at http://trevreport.org/blogForm.shtml. On the bottom of the page there is a little form for entering in your blog info, the output will be the HTTP requests and the resulting response.

If anyone can help I would be grateful.

We don't support WSSE authentication at this time, just HTTP Digest Authentication.

Ah, now it makes sense. Thanks for clearing that up for me.

Is there any plans to add WSSE authentication in the future?

Does HTTP digest Authentication HttpClient

I'm using HttpClient (commons-HttpClient-2.0.2) and Digest does not seem to work (keeps getting 401).

Here's the trace of the exchange:
