AtomPub + OAuth for Wordpress!
- body
-
After getting the answers I needed from the OAuth list, I decided to go back to hacking at getting OAuth to play nice with AtomPub on my host. I am pleased to report that it now works! It requires a two-line patch to Wordpress (for my host anyway, YMMV), and I had to change the wp-oauth plugin a bit (lastest in SVN), but I have successfully posted to my test blog using a remote AtomPub script authenticated using OAuth.
See some example code. The future is bright!

"Arbitrary" Communications?
- body
-
You have probably realised by now that I'm very interested in forms of communication and the best ways to go about improving them. What about communications from those you *do not* know? I can get telephone calls, SMS messages, emails, and Twitter @replies (among other things) from people who have not been whitelisted (aren't in my address book / on my friends list). Is this useful? What forms of communication suit it best? This poll started on Twitter, and I'm continuing it here and on PollDaddy.

Picoformats 0.20
- body
-
I have released an update to my Picoformats plugin. This update changes the logic so that posts are not modified in the database (thanks, @aditya!), but on the fly. It will also link to the local profile/archive of a user (thanks, @als!) that has no URL set in their profile. Also, if you use an @ reply from inside a comment and use the (one-word) name of a comment poster, it will recognize this (if they have whitespace in their name, just take it out when writing the @ reply). @ replies in comments also do not check Twitter usernames anymore, since this is expensive and breaks common use.

Picoformats for Wordpress
- body
-
This plugin is totally an experiment inspired in part by @techcrunch, and in part by how useful I have found some of this stuff to be on @Twitter, and also just to see the different ways one can use Wordpress. (Update: this plugin seem to only work on WP2.5, so I've upgraded.)
If you haven't guessed already, you soon will. Yes, I've implemented @ replies for Wordpress. It looks in the local users (usernames and nicknames, like @singpolyma) first, then in the names and descriptions on blogroll links, the it checks if you are trying to use a URL (like @singpolyma.net) and, finally, if none of those yield a result it checks if the string is a valid Twitter username. It produces semantic markup for an @ reply and "person tag":
<span class="reply vcard tag">@<a class="url fn" href="URL">NICKNAME</a></span>Then, the plugin sends trackback pings to the URLs, to let the people know you're talking about them. The plugin also implements trackback receiving on the Wordpress main page so that users can receive these pings.
Not to stop so short, the plugin also implements #hashtags. What that does should be fairly obvious.
These features work in posts *and* comments.

I uploaded a new AtomPub patch on that ticket, http://trac.wordpress.org/attachment/ticket/6995/wp-app.php.diff can you confirm that the new patch works as expected.
Hi Singpolyma,
I got some some errors when playing with your oAuth/Wordpress code. I will appreciate it if you could make some comments from the screen dump listed below. It seems the test passed oAuth but was not able to post to Wordpress. In this test, wp_app.php was in the oauth plugin folder. If there is nothing apparently wrong, maybe I should test the Wordpress Atompub separately. It looks like APE is difficult to setup, I think I should just try to use the cURL routines.

**I had to hard-code the callback_url. Otherwise, it would not work. If callback_url is simply commented out, wordpress will display "Authorized! You may now close this window"
$callback_url = "/wordpress/wp-content/plugins/wp-oauth/wp_app.php?action=access";
//$callback_url = "$base_url/wp_app.php?action=access";
Note: the last line in Common.inc.php has to be commented out in order to use wp_app.php in a different folder from the plugin iself.
@Ming RE (1) : have you applied the patch? You will get a 404 if you have not. If you have, can you send me the contents of $_SERVER for that request?
RE (2) : I have no idea if that's wrong… is there a specific problem?
RE (3) : This is expected behaviour
RE NOTE : What is your setup like? PHP should resolve __FILE__ to the file the statement is in, and then the relative path should work… always has for me.
Thank you very much. I reapplied the patch manually after I found that the patch command did not work as expected. Now it looks like this in file wp-app.php:
global $always_authenticate;
if( !empty( $_SERVER['ORIG_PATH_INFO'] ) )
$path = $_SERVER['ORIG_PATH_INFO'];
else
$path = $_SERVER['PATH_INFO'];
$method = $_SERVER['REQUEST_METHOD'];
log_app('REQUEST',"$method $path\n================");

This is the description about how the error still happened (wp_app.php in another folder)
Once I clicked the test button, I was redirected to the Wordpress to authorize the consumer right. I then clicked yes, then I got the error of non-existent URL "http://localhost/wp_app.php?action=access", which should be "http://localhost/oauthtest/wp_app.php?action=access"
Tring to make it work, I changed "$callback_url = "$base_url/wp_app.php?action=access" to "$callback_url = "http://localhost/oauthtest/wp_app.php?action=access"" because I thought something is wrong with the base_url.
I then cliked the test button again, this time the authorization window did not show up (already approved), I got an error as
"http://localhost/wordpress/wp-app.php/posts?oauth_version=1.0&oauth_nonce=a6c0ce38cff5bf899d072867d0d4694e&oauth_timestamp=1214025525&oauth_consumer_key=ccaa282c3f6c66cf0b2491b9f152e11ad4bd822c&oauth_token=faebda8608c455bfef6d2f0628fd5c055276659a&oauth_signature_method=HMAC-SHA1&oauth_signature=VzGlNOYOHhq1XaTL4wk9mWuiQsI%3D

string(215) "HTTP/1.1 404 Not Found"
I finally run through your code after making some minor changes:
1) In wp_app.php, I had to hard-code the callback-url because otherwise the base_url is empty.
//$callback_url = "$base_url/wp_app.php?action=access";
2) At first SCRIPT_URI was undefined in my server setup. This was fixed by configuring virtualhost and enabling RewriteEngine module.
3) Finally, this thing got work after commenting out one line in wp-app.php:
//$_SERVER['PATH_INFO'] = preg_replace( '/.*\/wp-app\.php/', ", $_SERVER['REQUEST_URI'] );
Then I was able to post on my Wordpress! Thanks for the work.
@Ming (1) wp_app.php is just a test script - not surprising you had to make some changes. (2&3) Might make sense to submit reports of some kind to WordPress, since those are requirements for WordPress AtomPub and not my plugin.
