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：

       use HTTP::Request::Common;
       use LWP::UserAgent;
       $user_agent = LWP::UserAgent->new;
       $request = GET 'http://clearcase/~xhzhu/cgi/cgireader.cgi?text1=hello&text2=here';
       $response = $user_agent->request($request);
       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;
        $co = new CGI;
        print $co->header,
        $co->start_html(
     -title=>'CGI Example',
     -author=>'yourName',
     -BGCOLOR=>'white',
     -LINK=>'red'
 );
       if ($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;
