accessing web service...

[shotokan99]

hi,

i was given a query string : http://mywebservice.com?url=<xurl where
xurl=is a valid url. now what the query string does it will display an
xml on the page. like this one:

<?xml version="1.0" encoding="UTF-8" ?>
<response...>
..
..
..
</response>

how can i trap the response using curl?

[shotokan99]

this is how i did it but i got no reply...

$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$xgo);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xresult=curl_exec($ch);

echo var_dump($xresult);

what to do to trap the response?

"no" reply, nothing, just hung?
is this a firewall issue, does the remote site accept requests from
the user agent, does the remote session require a cookie,

was it indeed "no reply"
were there headers - use a proxy to find out.
have you encoded the url in the get paramater properly.
have you tried it locally returning static xml, debug locally then set
it free.

oh and I suppose its worth asking, do you have cURL on your system at
all, try it from the command line?

i modified it using this code:
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$xgo);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xresult=curl_exec($ch);

echo var_dump($xresult);

the response is: httpstatus 403

>have you encoded the url in the get paramater properly.

yes. im completely sure that my parameters entries are 100% ok,
because i run it straight to the browser address bar and it gives a
valid xml response. i have no firewall issue becuase i tried to run
xml before and it was doin ok. the only difference to what i did
before is, im passing a formatted xml and this time the request is
done thru query string.

since you get a 403, you're right the data is going both ways so the
firewall doesnt seem to be a factor.
But remember I guess you were using a browser before, now you are
using php, that makes things completely different, I'm not sure what
you mean when you say that "the only difference to what i did before
is, im passing a formatted xml and this time the request is done thru
query string" - have you tried doing this in a browser, are you sure
it is acceptable, 403 means forbidden after all.
My guess would be that you are required to do things that a browser
does, change the user agent, and start accepting cookies, so that cURL
looks more like a browser, and finally send and receive the data just
as the browser does. You aren't far off, but remember that most web
services (free ones) wouldn't like to be thrashed by a program and may
well have retrictions - if it has a howto follow compltetly to the
letter, but you should be alright with just mimicking what works, cURL
can do it just required a few more options and tweaks.
