XML-RPC Newbie question. [Dec. 23rd, 2004|10:20 am]
LiveJournal Client Discussions


[mood |curiouscurious]

I am trying to get a better understanding of XML-RPC

I've manually created the getchallenge request. But for some reason I keep getting back a fault error. Any pointers or comments would be appreciated.

The set up:
I telnet directly to test.livejournal.com 80
I send the request
I receive the fault.

POST /interface/xmlrpc HTTP/1.0
POST /interface/xmlrpc HTTP/1.0
User-Agent: Apolo Agent 0.1d
Host: www.livejournal.com
Content-Type: text/xml
Content-Length: 136

<?xml version="1.0"?>

<?xml version="1.0" encoding="UTF-8"?>
<string>Application failed during request deserialization: 
unclosed token at line 8, column 0, byte 126 at /usr/lib/perl5/XML/Parser.pm line 185

Make sure that you calculate the Content-Length correctly. I'm too lazy to count bytes, but it's probably too short. (Maybe because of line-endings?). Try to paste in the example from the docs to see if that works.

One problem and curiosity seems to be that content length...

In the example page it lists the Length as: 193

However, counting from the 1st character from the POST line (depending on how CRs are counted) would cut off the example at:

Counting backwards from the end of the example 193 would put the first character at the Host line at the point: livejournal.com

So the content Length I list above is from counting characters from the point immediately after the Content-Length Value + 1 for and extra CR at the end.

Now, I'm not sure if my telnet client may be doing something strange with the CRs that are sent. But that's all that I have so far.

When I entered it manually (rather than cut and paste, the server reacted upon the last CR as if I did give it the correct Content Length.

Re: One problem and curiosity seems to be that content length...

Are you perhaps copying from another terminal/dos box. They tend to copy blocks, not chracters. So you'd get extra spaces :)
