Generating an ECP hash.

(Bumping this up from earlier comments in the hopes of assistance.)

I'm stuck on one issue. I've used the form sent out via comment emails as a basis, but I'm having a hard time generating the ECP hash.

In talklib.pl, the hash is generated like so:


sub ecphash {
my ($itemid, $talkid, $password) = @_;
return "ecph-" . Digest::MD5::md5_hex($itemid . $talkid . $password);
}

In PHP, I'm doing this:


$TalkID = '1010';
$ItemID = '010101';
$Password = 'mypassword';
$ECPHash = md5($ItemID . $TalkID . $Password);

However, the submitted form is rejecting the hash as having the wrong password. Is there some further munging of the password that needs to be done to generate a valid password for hashing? Or is the PHP md5() doing something different than the Perl library?

Now, I know the TalkID and the ItemID aren't the problem, which leaves me with one of two options:

1) The MD5 hashing functions work differently between PHP and Perl (which would be odd).

2) The password being used to generate the hash on LJ's side is not a clear-text password, but rather some sort of encrypted form of the password being pulled from their database

Any clues?

Edited To Add: Thank you,

soph! Here is the fixed and working code:


	$Journal = 'JournalReceivingReply';
	$Poster = 'UsernameOfReplyingParty';
	$TalkID = '01010';
	$DItemID = '101010';
	$JItemID = intval($DItemID/256);
	$Password = 'apassword';
	$ECPHash = md5($JItemID . $TalkID . $Password);

	echo '
<html>
	<body>
		<form method="post" target="ljreply" action="http://www.livejournal.com/talkpost_do.bml">
			<input type="hidden" name="usertype" value="user" />

editfriends XML-RPC issue.

Hi!

I'm trying to get my PHP-based XML-RPC client update friends' lists using the editfriends method, but I'm getting an odd response. Here's my PHP code:


	require('Configuration/Configuration.php');
	require($FunctionRoot . 'xmlrpc.php');

	// LJ XML-RPC Variables
	$add = array();
	$add['username'] = 'user_to_be_friended';
	$add['fgcolor'] = '#00688B';
	XMLRPC_prepare($add,'struct');

	$array = array();
	$array['username'] = 'professormass';
	$array['password'] = 'my_password';
	$array['add'] = $add;

	XMLRPC_prepare($array,'struct');

	$result = XMLRPC_request('www.livejournal.com','/interface/xmlrpc','LJ.XMLRPC.editfriends', array($array));

I get this response:

Application failed during request deserialization: wrong element 'username'

Virtually the exact same code works for using the postevent method. Anybody have any clues on this one?

Can't read protected entries after authenticating

Dear all,

I have written a php script through which to interface with LJ's XML-RPC interface (http://www.ratiosemper.com/xmlrpc.phps). When I supply the correct information, I can login correctly, generate a session cookie, store the session cookie, and access other parts of the LJ site that cannot be accessed via the XML-RPC interface, such as uploading user pics. I can even post and edit friend-locked entries in communities or journals.

The problem is this: when accessing the RSS feed for the community (or user), it does not display the protected entries. (if I try fetching the community or user page, it will also NOT show the protected entries)

Is there something more I should be doing? Is this even possible (I assume this is possible since LJ-Archive downloads protected entries)? (I know I can do this by posting my username/password to the login.bml, but I don't want to send my password in the clear.) (I have also tried sending the cookie as header through $curl->set_headers($header_array) and sending the 'X-LJ-Auth: cookie' header, but that didn't change anything.)

Thanks,
Steve

Digest auth in PHP through XMLRPC?

Hi gang,

Anyone has an example on how to do digest auth in PHP via the XMLRPC interface? I'm writing a friendslocked post browser and it going to take me the better part of the week just to figure out the authentication by myself.

EDIT: I might be out of luck. the XMLRPC API does not support Digest auth, only Challenge auth. It means I can not authenticate as one user and use my credentials to look at another user's post. Des anyone know of a way to use XML to look at a friendlocked post of someone else? Or do I have to page scrape?
