有时需要在perl中非交互地调用已有的cgi来完成一定的功能，此时需要模拟一个http请求来调用cgi。

 

get方式调用：

      1 use HTTP::Request::Common;
      2 use LWP::UserAgent;
      3 $user_agent = LWP::UserAgent->new;
      4 $request = GET 'http://clearcase/~xhzhu/cgi/cgireader.cgi?text1=hello&text2=here';
      5 $response = $user_agent->request($request);
      6 print $response->as_string;

post方式调用：

use HTTP::Request::Common;
use LWP::UserAgent;
$user_agent = LWP::UserAgent->new;
$request = POST 'http://clearcase/~xhzhu/cgi/cgireader.cgi',
    [text1 => 'Hello', text2 => 'there'];
$response = $user_agent->request($request);
print $response->as_string;

cgireader.cgi:

#!/usr/local/bin/perl
use CGI;
      4 $co = new CGI;
      6 print $co->header,
      8 $co->start_html(
    -title=>'CGI Example',
    -author=>'yourName',
    -BGCOLOR=>'white',
    -LINK=>'red'
);
     15 if ($co->param()) {
    print
        "You entered this text: ",
        $co->em($co->param('text1')),
        " ",
        $co->em($co->param('text2')),
        ".";
} else {
    print "Sorry, I did not see any text.";
}
print $co->end_html;
