Can't submit a form.

system · February 11, 2013, 4:11pm

hello
my script is submitting POST-data to a site
(its not my first script, i've done these before many times (include parsing scripts) but this one is tough)

so the problem is i'm submitting a form with firefox
and in firebug i see WHAT exactly i'm submitting
then
when i do EXACTLY the same with my script
it's simply not working
so i have the question to pro's:
WHYYYYYYYYYYYY

there is one thing.. the data have about 20 parameters and some of them:

__EVENTARGUMENT
__EVENTTARGET
__EVENTVALIDATION
__LASTFOCUS
__VIEWSTATE
>datahere<

can change their position in the block of post-data
they can be like:

__LASTFOCUS
>datahere<
__EVENTARGUMENT
__EVENTTARGET
__EVENTVALIDATION
__VIEWSTATE

or:

__LASTFOCUS
__EVENTARGUMENT
__EVENTTARGET
__VIEWSTATE
>datahere<
__EVENTVALIDATION

or somewhere else

and i think maybe javascript doing this somehow but dunno if this can be a problem
the whole site looks like writting by a monkey. rly. have bugs in JS and in HTML also.
there's also the key which is changing when loading this page but i'm catching it

PS plx don't put this topic to "web-programming" last answer there was a week ago

system · February 11, 2013, 4:46pm

$socket=IO::Socket::INET->new("$host:80");
defined $socket or die "!!! 029 $!\n";
        
print $socket "POST /script.aspx HTTP/1.1
Host: $host
User-Agent: $ua
Connection: keep-alive
Referer: http://$host/script.aspx
Cookie: $cookie
Content-Type: application/x-www-form-urlencoded
Content-Length: ".(length$content)."
        
$content";

If you cannot post your code, we cannot help you.

[edit] edit it in under me, why don't you.

From simple rules of the UNIX.COM forums:

Corona688 · February 11, 2013, 4:56pm

What is $host ? What is $content?

I'm not sure this looks right:

length$content

length $content

system · February 11, 2013, 5:00pm

you can't try it by yourself there's authorization
length$content works fine for all times
there's no mistakes in code, i've done it many times
my question was - why there some options changing places in data?
and why it working fine in browser and not working in script?

btw this __EVENTDATA some shit from ASP.net
some protection mechanism maybe

DGPickett · February 11, 2013, 5:20pm

Workin' too hard, length is optional.

kg_gaurav · February 11, 2013, 5:22pm

Post data doesn't need to be in specific order. They can vary and there's no problem because of that. In ASP.NET apart from post data whole html response of the page goes. Apart from that evendata,viewstate,cookies content etc. They all need not to be in order. So tell us what exactly is the difference between posting through firefox mozilla and through script

system · February 11, 2013, 5:25pm

there's NO difference
that's the problem

DGPickett · February 11, 2013, 5:25pm

Use truss/tusc/strace and look.

system · February 11, 2013, 5:28pm

lolwut?

kg_gaurav · February 11, 2013, 5:31pm

Not sure yet. What is your problem and what are you trying to do

system · February 11, 2013, 5:38pm

googled
compared every single symbol in FF and my script
googled
did rewrite it with LWP
googled
made few topics on few forums about alternative ways (like autofill the form with something like greasemonkey. the problem is that the data in mysql)
googled googled googled
analized analized analized
right now i'm reading about __eventvalidation

truss

strace

tusc -. trace UNIX system calls

Found after 5 seconds of heavy-duty Google use. "strace" and "truss" are tools used almost daily, "tusc" was news to me as i do not work on HP-Ux.

Google can be found at "www.google.com" with your favourite web browser.

Glad to be of help.

i know dude, thanks
but HOW they can help me here?

DGPickett · February 12, 2013, 1:14pm

They are very educational, and you can see exactly where it goes off the rails: where it gets the host, what host it is looking up, where it looks.

system · February 12, 2013, 1:15pm

firebug in firefox shows me all this

Corona688 · February 12, 2013, 1:21pm

firebug tells you what firefox is willing to tell you. These strace tools work at a deeper level.

system · February 12, 2013, 1:23pm

hmm
i never used it for that
so what i should do then?
