POST to page returns another page (to POST to)
Hello! I am using LWP to post to a web page. The
post works fine, but the $response the comes back
contains the HTML of _another_ page that I have to
POST to.
This is where I get stuck.
Normally when I $agent->request( POST $url [...] ) I
know the $url. In this case I don't have a url -- I
have a $response with some html inside of it. How do
I POST to this new page? (I tried using HTML::Form as
well, using the HTML::Form->parse( $content, $uri )
mechanism, but this simply posted to the original page
I POST'ed to).
Source and headers given below.
Thanks in advance!
---------------------------src------------------
$url =
"http://fapt.efanniemae.com/eprosupp2/Content.jsp";
my $res = $ua->request( POST $url,
[ byPool => "false", poolOrCusip => "cusip",
bodyPage => "SearchCheck.jsp",
formAction => "search",
key1 => "31390JPE5",
key2 => "", key3 => "", key4 => "",
key5 => "", key6 => "", key7 => "", key8 => "",
key9 => "", key10 => "", key11 => "",
key12 => "", key13 => "", key14 => "",
key15 => "", key16 => "", key17 => "",
key18 => "", key19 => "", key20 => "",
RetrieveSupps => "Retrieve+Supplements" ] );
Carp::croak( "could not POST to $url , reason:" .
status_message( $res ) )
unless $res->is_success;
#this is where I get stuck.
#the form that comes back takes POST arguments
#formAction=retrieve&
#RetrieveSupps=Retrieve+Supplements
#how do I issue the post to this new page?

[...] I'm sure LWP will do this redirect for you if you ask it right, but: a) IIRC all POSTs are redirected as GET, not POST. b) To get the url, look in the Location header (unless this redirect is done with a Refresh header (which may be in a META HTTP-EQUIV tag in the HTML, but IIRC LWP will add it to the headers automatically).
