I am currently using Perl to write a program which can automatically submit information to some websites with LWP, getting results, which i print in a table on my own website. For most of the pages, it works well, but for one it doesn't:
After submit, I get a redirection to a captcha (no need of any complex solving her, after extracting the captcha, i want the user to solve it and enter the code). However once i want to post the reply to reach to the result page, the session get reloaded and I can not fetch the result page.
Whats going wrong?
#extracted captcha picture before, and catched user's reply in $captch
+a
#trying to submit captcha code:
$param="numIg=&numDgc=&numIgc=&numIp=&pageSize=3&strWhere='.$mySearch.
+'&numDg=&numIpc=&numUgc=&numUgd=&strLicenseCode=&numIgd=&showType=1&n
+umSortMethod=&strSources=&numUg=&pageNow=1&vct='.$captcha.'&Submit=%E
+7%BB%A7%E7%BB%AD";
$Search_url ="one website";
$request = HTTP::Request->new('POST', $Search_url);
$request->header('Accept' => 'text/html,application/xhtml+xml,applicat
+ion/xml;q=0.9,*/*;q=0.8');
#$request->header('Accept-Language' => 'de,en-US;q=0.7,en;q=0.3');
$request->header( 'Referer' => "one webiste");
$request->header('Connection' => 'keep-alive');
$request->content($param);
$response = $ua->request($request);
$page = $response->decoded_content();
print $page;
If i visit the html page, i can enter the captcha code and get to the result page directly. To compare, the request observed by the firefox plugin looks as following:
