bgold Posted September 23, 2012 Share Posted September 23, 2012 I am trying create a php script to that logins to a specific site that does a __doPostBack to submit the form. If I run the script I get an output of the form as if I had not sent any post data. I know I have to do something with the view state and the event val but I'm just so confused. I honestly have tried a whole bunch of different CURL scenarios I don't know what to post here. If anyone could give me an example of what I need so it at least recognizes that I am trying to POST data that would be awesome. Any help would be greatly appreciated. <?php $url="https://www.domain.com/Default.aspx"; $header = array("POST /Default.aspx HTTP/1.1", "Host: www.domain.com", "Connection: close", "User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)", "Accept-Encoding: gzip", "Accept-Charset: ISO-8859-1,UTF-8;q=0.7,*;q=0.7", "Cache-Control: no", "Accept-Language: de,en;q=0.7,en-us;q=0.3", "Referer: https://www.domain.com/Default.aspx", "Content-type: application/x-www-form-urlencoded", "Content-length: 0" ); $regexViewstate = '/__VIEWSTATE\" value=\"(.*)\"/i'; $regexEventVal = '/__EVENTVALIDATION\" value=\"(.*)\"/i'; function regexExtract($text, $regex, $regs, $nthValue) { if (preg_match($regex, $text, $regs)) { $result = $regs[$nthValue]; } else { $result = ""; } return $result; } curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); $data=curl_exec($ch); $viewstate = regexExtract($data,$regexViewstate,$regs,1); $eventval = regexExtract($data, $regexEventVal,$regs,1); $post = "ctl00%24cb%24txtSiteLoginName=asd&ctl00%24cb%24txtSitePassword=123123&__VIEWSTATE=$viewstate&__EVENTVALIDATION=$eventval"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)'); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_VERBOSE,1); curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt"); curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS,$post); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_FAILonerror, 1); curl_setopt($ch, CURLOPT_REFERER, 'https://www.domain.com/Default.aspx'); //curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $curlres = curl_exec($ch); ?> I have attached a html of the page and the POST data that I received from Chrome Web Developer when I log into the site. test.html data.txt Quote Link to comment Share on other sites More sharing options...
bgold Posted September 23, 2012 Author Share Posted September 23, 2012 (edited) I think this may be the appropriate post data but I'm not sure $postData = "__LASTFOCUS=&__EVENTTARGET=&__EVENTARGUMENT=&__VIEWSTATE=$viewstate&__VIEWSTATEENCRYPTED=&__EVENTVALIDATION=$eventvalidation&ctl00%24txtSearch=&ctl00%24cb%24txtSiteLoginName=$username&ctl00%24cb%24txtSitePassword=$password&ctl00%24cb%24btnLogin.x=30&ctl00%24cb%24btnLog.y=14&ctl00%24cb%24txtLoginName=&ctl00%24cb%24txtPassword=&ctl00%24cb%24txtTransactionid="; Edited September 23, 2012 by bgold Quote Link to comment Share on other sites More sharing options...
