PHP - Php Curl Help With Session Hash
Im trying to access a page that uses a session hash in the url. How do I accomplish this. The url looks like: http://www.somesite.com/findagent/MapController.aspx?action=getAgentsByRadius&distance=5&filter=PL&sessionhash=%3F%01j%23%3Eo%0AH%05h%0B%3FU%0B%3F%3F%3F%7B%3F%3C&zip=91111
I guess getting the session id and urlencoding on my end wouldnt work? I would have to grab their session id and encode somehow? Similar TutorialsI have a login system Username and Password.
My password is encrypted with bcrypt, if it okay to store that bcrypt in a session as $_SESSION["hash"]
To verify that the user is who they say they are?
Or do i only need to do
$_SESSION["username"]
Hi, I am having trouble with my cURL call because when I run the exec method I loose my current login state in the session. I have tried the two options below, but they have yet to succeed. If there is anything else you want me to tell you that will help you understand my issue, please let me know. $sessionfile = fopen("sessionfile.txt", "w"); fputs($sessionfile, session_encode( ) ); fclose($sessionfile); $c->setopt(CURLOPT_COOKIEFILE, $sessionfile); $c->setopt(CURLOPT_COOKIEJAR, $sessionfile); $sessName = session_name(); $_COOKIE[$sessName] = session_id(); $_COOKIE['aud_logged_in'] = Session::isLoggedIn(); session_write_close(); $c->setopt(CURLOPT_COOKIE, $sessName."=".$_COOKIE[$sessName].";"); Hi to everyone, I'm new to the forum and I'm posting here because I ended up in a logical problem for my next script development.
I need to get some data of external websites (with vbulletin board), perfectly legal.
Using file_get_contents i can print the page content on my server and then use jquery's powerful selectors to get my data.
The problem is that these data are shown only to logged in users so i would need this script (maybe using cURL?) to either login to the external website and then persists the connection or maybe if the user who is executing my script is already logged in that website then use his login? (most likely impossible I think..)
This is my code so far (found on some sites and merged into this)
$data = array('vb_login_username' => 'Scanu', 'vb_login_password' => 'grgfgrgrfbtgbt');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.vbulletin.org/forum/login.php?do=login");
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);
$pattern = "#Set-Cookie: (.*?; path=.*?;.*?)\n#";
preg_match_all($pattern, $result, $matches);
array_shift($matches);
$cookie = implode("\n", $matches[0]);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.vbulletin.org/forum/");
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
It just shows the same page for unregistered users. Any help or advice is appreciated, i'm very new to this type of script..I'm trying to post to a (SMF) simplemachines 2.0 forum using curl. I have logged in and I have tried sending all the fields, but when I try to post, I receive this message: "The following error or errors occurred while posting this message: Your session timed out while posting. Please try to re-submit your message." Do any of you know why this happens? Is the problem that when I visit the posting url, they give me a cookie that expires if I leave the posting url? I don't think the form is invalid, it looks like it has to do with the session. People at the simplemachines forum can have this problem when they try to post the ordinary way, but that is because of an inactivity period. Can my problem be because of a cookie? good day dear community, i am workin on a Curl loop to fetch multiple pages: i have some examples - and a question: Example: If we want to get information from 3 sites with CURL we can do it like so: $list[1] = "http://www.example1.com"; $list[2] = "ftp://example.com"; $list[3] = "http://www.example2.com"; After creating the list of links we should initialize the cURL multi handle and adding the cURL handles. $curlHandle = curl_multi_init(); for ($i = 1;$i <= 3; $i++) $curl[$i] = addHandle($curlHandle,$list[$i]); Now we should execute the cURL multi handle retrive the content from the sub handles that we added to the cURL multi handle. ExecHandle($curlHandle); for ($i = 1;$i <= 3; $i++) { $text[$i] = curl_multi_getcontent ($curl[$i]); echo $text[$i]; } In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle! If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it! Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages: see the some details for this target-server sites - /(I have to create a loop over several hundred sites). * siteone.example/?show_subsite=9009 * siteone.example/?show_subsite=9742 * siteone.example/?show_subsite=9871 .... and so on and so forth Question: How to appy this loop into the array of the curl-multi? <?php /************************************\ * Multi interface in PHP with curl * * Requires PHP 5.0, Apache 2.0 and * * Curl * ************************************* * Writen By Cyborg 19671897 * * Bugfixed by Jeremy Ellman * \***********************************/ $urls = array( "siteone", "sitetwo", "sitethree" ); $mh = curl_multi_init(); foreach ($urls as $i => $url) { $conn[$i]=curl_init($url); curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string curl_setopt($conn[$i],CURLOPT_FOLLOWLOCATION,1);//follow redirects curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout curl_multi_add_handle ($mh,$conn[$i]); } do { $n=curl_multi_exec($mh,$active); } while ($active); foreach ($urls as $i => $url) { $res[$i]=curl_multi_getcontent($conn[$i]); curl_multi_remove_handle($mh,$conn[$i]); curl_close($conn[$i]); } curl_multi_close($mh); print_r($res); ?> I look forward to your ideas. Guys, Having a major headache here. I need to send an enquiry using jquery and php. The user can only send an enquiry if they are logged in - so it's a one click process. On the click (which is an <a> tag) the user's data is retrieved from the database and sent to the company they are enquiring about. When the link is clicked, a jquery popup is shown to notify the user that the enquiry has been sent. This all works. However, currently the enquiry is sent when the page loads and this is what I'm having trouble with. Code: [Select] <a href="#e" onclick="openinfobox('Enquiry Sent', 1)" class="enq"></a>What I want to do is say if the URL contains #e, then send the enquiry, otherwise do nothing. I understand that the # portion of the url cannot be referenced by PHP. How on earth can I run php process to say only run this php process if there is a # in the url? I have a section on my website where the url points to www.example.com/some_page#some_element #some_element is used by javascript to load the element in question into the parent element. However i need pagination done on this loaded element. How should i go about it? would it work? obv i cant use www.example.com/some_page#some_element/page/2. Any tips or advice? Are there any PHP hashes that are extremely secure and that CANNOT be reverse-engineered?
Is a hash array the same thing as an associative array? My PHP books make no reference to this, yet I have seen the term referred to. Thanks. When a User changes his/her Email Address, should I generate a new Salt and Hash? (I am re-using the code I used for a Password Reset, and during that I generated a new Salt and Hash for security. I guess it can't hurt...) Thanks, Debbie Hi,
Recently I've been trying writing a safe password hash and I wanted to know that if I use an MD5 hash at the end, just so it will be like some short of "packed",so instead of saving a 128 string, I'll use md5 to "pack" it into 32 characters and save up to 96 characters.
I know MD5 isn't safe and all, but the question is, does it lower the security ?
Also, would be happy for feedbacks about my password hash
function hash_($input,$key) {
$op=hash("whirlpool",hash("sha512",$key) . "$" . $input . "$" . hash("sha512",$key));What is the difference between the hash algo "tiger192,3" and "tiger192,4"? I ran fsum/HashCalc to get a TIGER hash from a string and it is different with either "tiger192,3" or "tiger192,4". I also tried using the hash as hex string input to rehash 3 or 4 times, but still cannot get an equivalent to that of "tiger192,3" or "tiger192,4"... HI, I have a registration script where a password is made with one hash, and a user password reset page that uses another hash. I don't know how to make them the same, as every time I change them, it messes up the code and I get errors. I will comment the parts that I think need changing. Because when I try to log in with the new password that was made by the reset password script, it says "wrong username or password" because either it wasn't updated in the database, or it was updated in a bad way. Any help greatly appreciated. The password email reset code: Code: [Select] <?php define('IN_SCRIPT', true); // Start a session session_start(); ini_set ("display_errors", "1"); error_reporting(E_ALL); $host = ""; $database = ""; $username = ""; $password = ""; $tbl_name = ""; $conn = mysql_connect($host, $username, $password) or die("Could not connect: " . mysql_error()); if($conn) { mysql_select_db($database); echo "connected to database!!"; } else { echo "failed to select database"; } //this function will display error messages in alert boxes, used for login forms so if a field is invalid it will still keep the info //use error('foobar'); function error($msg) { ?> <html> <head> <script language="JavaScript"> <!-- alert("<?=$msg?>"); history.back(); //--> </script> </head> <body> </body> </html> <? exit; } //This functions checks and makes sure the email address that is being added to database is valid in format. function check_email_address($email) { // First, we check that there's one @ symbol, and that the lengths are right if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) { // Email invalid because wrong number of characters in one section, or wrong number of @ symbols. return false; } // Split it into sections to make life easier $email_array = explode("@", $email); $local_array = explode(".", $email_array[0]); for ($i = 0; $i < sizeof($local_array); $i++) { if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) { return false; } } if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP.

what would be the correct way to add an MD5 has to the following POST code? $_POST['pass'] = mysql_real_escape_string($_POST ['pass']); '".$_POST ['pass']."', thanks in advance! Trying to echo a string that contains a hash symbol. Instead of getting a hash symbol, I get %29. The code I am using is pretty basic -->$idx="#" . $idxA;<--, but as stated, when I echo $idx, it comes out as %29. (All of this is part of a form, get, attempting to pass a bookmark to the receiving program. Thoughts? Hi SMF forum use semi-colom in url for example http://www.phpfreaks.com/forums/profile/?area=showposts;u=71740 after showposts there is semi-colon. Sometimes use hash(#) how can i do this with superglobal $_GET??? Hello, I created a system where emails get encrypted with a random key that gets stored in a database, what are the odds of the Hashes Colliding? Part of the code: function genRandomString($num) { $length = $num; $characters = '0123456789abcdefghijklmnopqrstuvwxyz'; $string = ""; for ($p = 0; $p < $length; $p++) { $string .= $characters[mt_rand(0, strlen($characters))]; } return $string; } $Key=genRandomString(10); $email_s=hash_hmac('ripemd160', $email, $Key); Thankyou, GB. Im using SMF forum im trying to connect (my software C#) and grand access from forum DB this is a hash from SMF sha1(strtolower($membername) . $password); Code: [Select] <?php include("config.php"); $user = "-1"; if (isset($_GET['user'])) { $user = $_GET['user']; } $pass = "-1"; if (isset($_GET['pass'])) { $pass = $_GET['pass']; } $ip = $_SERVER['REMOTE_ADDR']; $sql = "select id_member,count from smf_members where real_name='$user' and passwd=MD5('$pass')"; $results = mysql_query($sql, $con); $values = mysql_fetch_assoc($results); $user_id = $values['id_member']; $login=$values['count']; ?> MD5 working fine but how to use SMF hash to login? $hash = file_get_contents("url"); the source code has this '<input type="hidden" name="hash" value="Mr607qtwQQuX">' how could I get preg_match or explode to parse out just the hash Mr607qtwQQuX? thanks |
