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：

      1 use HTTP::Request::Common;
      2 use LWP::UserAgent;
      3 $user_agent = LWP::UserAgent->new;
      4 $request = POST 'http://clearcase/~xhzhu/cgi/cgireader.cgi',
      5     [text1 => 'Hello', text2 => 'there'];
      6 $response = $user_agent->request($request);
      7 print $response->as_string;

cgireader.cgi:

      1 #!/usr/local/bin/perl
      2 use CGI;
      3
      4 $co = new CGI;
      5
      6 print $co->header,
      7
      8 $co->start_html(
      9     -title=>'CGI Example',
     10     -author=>'yourName',
     11     -BGCOLOR=>'white',
     12     -LINK=>'red'
     13 );
     14
     15 if ($co->param()) {
     16     print
     17         "You entered this text: ",
     18         $co->em($co->param('text1')),
     19         " ",
     20         $co->em($co->param('text2')),
     21         ".";
     22 } else {
     23     print "Sorry, I did not see any text.";
     24 }
     25 print $co->end_html;

完！
