Q&A
> CGI programming
Description: The html is in the follwing format:
<html>
<head>
<title>someTitle</title>
</head>
<form action="../cgiDir/go.pl" method=POST>
<input type=hidden name="a" value="aswdc">
<input type=hidden name="b" value="4">
<input type="submit" name="B1" value="Submit">
</form>
</body>
</html>
The cgi is in the following format:
#usr/etc.
use CGI;
use HTTP::Request::Common;
use LWP::UserAgent;
$query = new CGI;
$query->use_named_parameters(1);
$var1 = $query->param('a');
$var2 = $query->param('b');
$ua = new LWP::UserAgent;
$req=POST 'http://www.someqURL.com',[v1=>$var1,v2=>$var2];
print $ua->request($req)->as_string;
exit 0;
I keep on getting a Server error. What am I doing wrong?
Thanks in advance. Answer: How do post to a URL from a form and display the results in a browser?
contributed by icuc I think this , perhaps , could satisfy your need.
---------------------------
#!/user/local/bin/perl
use strict;
use CGI;
use HTTP::Request;
use LWP::UserAgent;
my $q = CGI->new();
$q->use_named_paramters(1);
my $var1 = $q->param('a');
my $var2 = $q->param('b');
my $ua = LWP::UserAgent->new();
my $method = "POST";
my $url = "http://where_you_want";
use HTTP::Header;
my $header = HTTP::Header->new();
my $content = "v1=".$var1."&v2=".$var2;
my $request = HTTP::Request->new($method, $url, $header, $content);
use HTTP::Response;
my $response = $ua->request($request);
if($response->is_success) {
print $response->content;
}
else {
print $response->error_as_HTML;
}
-------------------------------------
for more details, please check Perl's Documents
HTTP::Request, HTTP::Header, HTTP::Response, LWP::UserAgent, etc.

contributed by rodry Not that I am an expert on this PERL thing, but in my experience a server error is simply a generic error message the web server generates when a script craps out.
What I would do is check the apache logs and see exactly what the error could be.
By the way, did you try the script from the console? | Answer: How do post to a URL from a form and display the results in a browser?
contributed by icuc yes, I run script from console!!
a server error? 502? or other? | Answer: How do post to a URL from a form and display the results in a browser?
contributed by merlyn If you're running this as a CGI program (as your use CGI would imply), I fail to see where you are printing the appropriate
CGI header. Add
print $query->header, $query->start_html("some title");
before the rest of your program.
