I am a ruby newbie and tried to use a http client to send the XML HTTP
POST request to my cgi,
I thought I can get the text I input in the HTTP POST directly from the
$stdin as a string in cgi and extract the data out. but it didn’t seem
to work.
I tried to do $stdin.realines to parse every line of the $stdin but I
got nothing out of it.
Are you using the cgi library from the stdlib?
If so, it reads the params from $stdin and gives you access to them
as a hash. Take a look at this example:
well… i only followed the instruction. trying to see if those
parameters came in
Nobody on the ruby forum has any idea what your software does with this:
www.xxxurl.com
DATA_TYPE
IMAGE
A request containing post data is sent to the server with name/value
pairs in the body of the request. Maybe your
software interprets that xml as an instruction to send a request to www.xxxurl.com, with the name/value pairs DATA_TYPE=IMAGE.
By the way, you can also get the individual parameters like this:
Sorry about misleading, I think my problem is that I cannot get any POST
data in my CGI, I tried your suggestion above and looks like the POST
data did not come through.
do you know what’s possibly the reason?
or do you have any format recommend in the POST data? the only thing
that matter to me is to get the url data so my cgi script can take that
url to do the rest of the work.

Try this as a way to diagnose the issue:
require 'cgi'
cgi = CGI.new
cgi.params.each_pair {|k,v| puts k + ' => ' + v }
That should tell you exactly what parameter keys and values are being
sent to your Ruby script. If you’re actually viewing the output in the
browser, you might want to try adding some markup:

Do you have to use that request software? You can easily test whether
your server’s cgi gateway is working by using a ruby script to send the
post request:
data = {
‘my_url’ => ‘http://www.some_site.com’
} #That hash should include all name/value pairs you #want to send to the server
response = Net::HTTP.post_form(url, data)
puts response.body
That will also work if both scripts are on localhost–just start up your
server script, then in a different terminal window execute your request
script.
You should start by writing a cgi script that just echos back the info
it received, like Chad P. showed you. Once you know that everything
is working correctly with the cgi gateway, then you can figure out why
your original script isn’t working.
