getrecentcomments

Wed, 01 Sep 2010 15:31:09 GMT

Hi!
I am trying to get recent comments via LJ.XMLRPC.getrecentcomments.
It appears that the output of this function does not give enough information to make subsequent postcomment to reply to a received comment (ditemid and parent parameters for addcomment are missing). Sending "trim_widgets" or "parseljtags" seems to be supposed to receive full comment URL but it returns an error "can't call method "url" on unblessed reference at/home/lj/cgi-bin/ljrotocol.pl line 349".
Additionally, it seems to work only for a paid account though web version works for free account too. For my free account it returns empty comment list without error message.
Edit: it actually returns comments for a free account, the problem was that I had there all entries private. That means that it returns only comments to public entires.
Could it be fixed?

Internal Server Error 500

Sun, 22 Aug 2010 15:37:35 GMT

I develop the Mac OS X client Phoenix.

Lately, some of my users have been reporting an issue where Livejournal generates an Internal Server Error (500) when attempting to post using the client. When it occurs it usually persists for a while (an hour or more), but it occurs intermittently and seemingly without pattern. It happened to me when trying to post this entry (with a different example attached), so I've attached the post request I sent that failed.

I imagine this is related to the other issues with clients who post using the flat method.

UPDATE: It's definitely an issue with Unicode. Posting non-roman Characters duplicates the problem 100%. I've had Unicode implemented successfully in the client (I thought?) for the last seven years with no problems. Is Livejournal broke or did they change something with their unicode implementation permanently?

Digest authentication failed.

Mon, 16 Aug 2010 16:07:39 GMT

There's a couple tickets that refer to a digest authentication failure recently, for requests that worked fine a few months ago:

http://www.livejournal.com/support/see_request.bml?id=1139934
http://www.livejournal.com/support/see_request.bml?id=1140658

One was marked as "reported to LiveJournal's development staff for further troubleshooting".

Any insight from anyone here as to what's going on? Is this related to the previous "Client error: No mode specified" post at all? Is there any working method of writing a script to retrieve RSS feeds with authentication currently?

Client error: No mode specified

Sat, 14 Aug 2010 14:58:55 GMT

A few days ago, I started to get the "Client error: No mode specified" when I tried to post to LJ using my client. Sometimes it would work, and sometimes it wouldn't. (If it failed, I just tried again and it usually worked on the second attempt.) Now I'm getting it every time I try to post. Is there a problem with the LJ flat interface? I recall there was a similar problem earlier this year.

HTTP post question "Invalid Year"

Thu, 12 Aug 2010 15:37:48 GMT

Hi. I'm only just starting to teach myself client scripting, I ran into a little problem which I can work around, but I would still like to know if anyone can tell me why this was happening:

date_ymd_mm=8&date_ymd_dd=12&date_ymd_yyyy=2010&hour=18&min=53

When I post to http://www.livejournal.com/interface/flat it tells me that the year is invalid.

But when I post the exact same date to http://www.livejournal.com/update.bml it works fine.

What is it about /interface/flat that won't accept the year?

xml-rpc

Thu, 29 Jul 2010 13:44:14 GMT

Hi everyone,
I am doing thesis about social networks. I need to crawl user profiles from LiveJournal in order to use the data to test my own model. The question is I don't know how to use LJ xml-rpc. I intend to get the data in format of foaf. Java is my preferred language. Do I need to download any LJ api? If anyboday can give any examples or similar case, I appreciate . I am new here, so if my question sounds silly, please...

Reliably predict urls?

Sat, 24 Jul 2010 14:38:38 GMT

It there a way to predict the url of a comment based the information that you get from xml export? I need to do this for a little project I'm working on.

Sat, 24 Jul 2010 14:36:14 GMT

I know this must be old news by now, but is there any client that will allow me to download the content of my Scrapbook? It doesn't need to be neat, so long as it comes down I can make the order later.

OAuth

Fri, 16 Jul 2010 14:55:05 GMT

Do the LJ APIs include any support for OAuth? Or are there any plans to add such support?

Thanks.

Batch edit old entries?

Wed, 14 Jul 2010 19:27:10 GMT

I'm looking for an application to change privacy settings en masse. With 1000+ entries I really don't want to do this by hand...

I'm running Win 7.

If anybody has any suggestions it would be muchly appreciated. Google hasn't been overly helpful...

LJ.XMLRPC.addcomment

Tue, 13 Jul 2010 14:39:44 GMT

Hello all

I see there is LJ.XMLRPC.addcomment method is present in the API

Does anybody have xml sample for it?

"Last Updated" date?

Wed, 07 Jul 2010 15:28:43 GMT

I'm writing an app which aggregates the "Last Updated" (date of most recent post) dates for my flist. What is the recommended way of getting at that data? I'm currently screen scraping the profile pages, and that seems unnecessarily processor intensive on both LJ's end and mine. Is that data exposed anywhere more convenient/less antisocial to get programmatically?

Making use of [...]/data/foaf

Wed, 16 Jun 2010 15:51:50 GMT

Hi,

I actually posted this as a support request, but they referred me to this community :P I would really appreciate any kind of help in this matter.

I was hoping that you could give me any advice on how to use the information provided on http://exampleusername.livejournal.com/data/foaf. I would like to use three sets of info on that page for a project I am working on, but none of the regular scripts seem to be able to handle the information provided.
Or is there any other way that I can fetch and cache information like last time updated or number of members for a community? Pulling it from the profile page directly would cause quite a server load and I wouldn't know how to cache it that way.

Thanks a lot!

"Friend of" counter

Sun, 13 Jun 2010 16:47:00 GMT

Hello everobody!
I'm going to make some blog rating php website and I will need to have a number of people who are reading the given livejournal user.
So I've googled and found the fdata opportunity.
For my jounal the link "http://www.livejournal.com/misc/fdata.bml?user=ajayver" works Ok, and I can just count the quantity of "<" symbols in this bml file to get the exact number of readers. But, for examle, I'm trying to use the same link for the journal of "dubrovskaya" user (http://www.livejournal.com/misc/fdata.bml?user=dubrovskaya) and the bml file contains only ~2600 lines, while there snould be more than 4000 readers...
Does anyone know what am I doing wrong, or is there any other way to make the "friend of" counter?
Thank you!

Examples for using the API?

Sun, 30 May 2010 12:43:09 GMT

Hi all,
I'm trying to use the Client/Server Protocol, but found it a little confusing. Does anyone have some examples that could show me how to get started with the protocols?
And, what I'm trying to do is to download a list of users(maybe all the members in a community, or all the friends of a given user) and their entries. Is that possible? Do you have any suggestion for me?
Thanks a lot.

LJ Client/Server protocol question

Fri, 28 May 2010 15:39:37 GMT

I wonder if I can use "getevents" method to access posts of users other than myself?
If yes, please point me to a relevant example.

update.bml

Thu, 06 May 2010 12:27:44 GMT

How can I form a string for update.bml script to post in LJ via GET method? The event field gets formed with the contents of the "event" argument I know:
http://www.livejournal.com/update.bml?event=blabla+content+blabla
But if I put there a link with "=" sign (bookmarking service script in Invision Power Board, for example: http://www.livejournal.com/update.bml?mode=full&subject=test&event=http://oshoforum.ru/index.php?showtopic=1504) all I see is just message of 'http://oshoforum.ru/index.php?showtopic' without any text after the sign of equality and without sign of equality itself.

fotoup.pl gives server error 500

Sun, 25 Apr 2010 12:39:19 GMT

Just got the following issue with fotoup.pl:

$ ./fotoup.pl Uranus.gif
Reading local files...

Getting challenge...

To upload: 1 from data, 0 from receipt

Uploading from data: Uranus.gif

Looking through the source code I did not notice any violation of the protocol documented at

Data-ObjectDriver repo moved

Thu, 22 Apr 2010 16:09:31 GMT

The Data-ObjectDriver repository was moved recently, and running "$LJHOME/bin/cvsreport.pl -u" with the stock LiveJournal multicvs.conf will result in an error message along the lines of:

Updating CVS dir 'Data-ObjectDriver' ...
A WE_HAVE_SWITCHED_TO_GITHUB.txt
U README
Updated to revision 579.

$LJHOME/cvs/Data-ObjectDriver/README contains:

THIS REPOSITORY IS NOT MAINTAINED ANYMORE

please use http://github.com/sixapart/data-objectdriver instead

Thank you.

To upgrade, run your usual before-upgrade backup procedure, then change $LJHOME/cvs/livejournal/multicvs.conf along the lines of http://hg.dwscoalition.org/dw-free/raw-rev/0845df63214b (that patch won't apply on a stock LiveJournal multicvs.conf, but it shows what you need to change. (And you should use the URL in the patch, not the one in the README.) After making the change, upgrade your live area as usual, then run the following commands:

rm -rf $LJHOME/cvs/Data-ObjectDriver
$LJHOME/bin/cvsreport.pl --checkout

Check that the content of $LJHOME/cvs/Data-ObjectDriver looks reasonable, then upgrade your live area as usual (yes, again). Once you've done that, you should stop and restart all TheSchwartz clients and workers, and monitor them carefully for a few days, as TheSchwartz is the main user (or perhaps the only user - I don't remember ATM) of Data-ObjectDriver.

Friends security level does not work

Tue, 20 Apr 2010 18:43:32 GMT

I am trying use LJ API. But I can't set visibility of new post for friends only. when i do postevent with security=friends, new post is created visible for all. if specify security=private - it works OK, post is not visible anybody except me. And I can't find anything about it around Net - only one link that friends security level didn't work for one guy when he posted from e-mail. Can anybody clear the situation? Thanks!

Tue, 20 Apr 2010 15:44:42 GMT

Hey there all,

I'm using an ancient perl-based LJ client, jlj, to post (it's easy and shell-based), and has a number of features I've grown used to. I'm presently revamping it to use more modern auth.

However, for about the past month, it seems that as soon as I attempt to log in, I get connection closed, no errors returned, no nada.

What seems to be worse is that it is doing this specifically on my host (72.9.101.130), as I tried via telnet from another host in another state and got in fine.

If there's some sort of blocklist in play, how would I find out how to clear it up, or apply for an exemption?
