Logging into secure site using CURL [duplicate] - php

Question

I'm new to using cURL and its hard to find good resources for it.
What I'm trying to do is login to a remote site, by having curl do the login form and then send back that it was successful.
The code I have doesn't seem to work and only tries to show the main page of the site.
$username="mylogin#gmail.com";
$password="mypassword";
$url="http://www.myremotesite.com/index.php?page=login";
$cookie="cookie.txt";
$postdata = "email=".$username."&password=".$password;
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt ($ch, CURLOPT_REFERER, $url);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec ($ch);
echo $result;
curl_close($ch);
What am I doing wrong. After this is working I want to redirect to another page and get content from my site.

Answer 1

I had let this go for a good while but revisited it later. Since this question is viewed regularly. This is eventually what I ended up using that worked for me.
define("DOC_ROOT","/path/to/html");
//username and password of account
$username = trim($values["email"]);
$password = trim($values["password"]);
//set the directory for the cookie using defined document root var
$path = DOC_ROOT."/ctemp";
//build a unique path with every request to store. the info per user with custom func. I used this function to build unique paths based on member ID, that was for my use case. It can be a regular dir.
//$path = build_unique_path($path); // this was for my use case
//login form action url
$url="https://www.example.com/login/action";
$postinfo = "email=".$username."&password=".$password;
$cookie_file_path = $path."/cookie.txt";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
//set the cookie the site has for certain features, this is optional
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,
"Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postinfo);
curl_exec($ch);
//page with the content I want to grab
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/page/");
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
curl_close($ch);
Update: This code was never meant to be a copy and paste. It was to show how I used it for my specific use case. You should adapt it to your code as needed. Such as directories, vars etc

I had same question and I found this answer on this website.
And I changed it just a little bit (the curl_close at last line)
$username = 'myuser';
$password = 'mypass';
$loginUrl = 'http://www.example.com/login/';
//init curl
$ch = curl_init();
//Set the URL to work with
curl_setopt($ch, CURLOPT_URL, $loginUrl);
// ENABLE HTTP POST
curl_setopt($ch, CURLOPT_POST, 1);
//Set the post parameters
curl_setopt($ch, CURLOPT_POSTFIELDS, 'user='.$username.'&pass='.$password);
//Handle cookies for the login
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
//Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
//not to print out the results of its query.
//Instead, it will return the results as a string return value
//from curl_exec() instead of the usual true/false.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//execute the request (the login)
$store = curl_exec($ch);
//the login is now done and you can continue to get the
//protected content.
//set the URL to the protected file
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/protected/download.zip');
//execute the request
$content = curl_exec($ch);
curl_close($ch);
//save the data to disk
file_put_contents('~/download.zip', $content);
I think this was what you were looking for.Am I right?

View the source of the login page. Look for the form HTML tag. Within that tag is something that will look like action= Use that value as $url, not the URL of the form itself.
Also, while you are there, verify the input boxes are named what you have them listed as.
For example, a basic login form will look similar to:
<form method='post' action='postlogin.php'>
Email Address: <input type='text' name='email'>
Password: <input type='password' name='password'>
</form>
Using the above form as an example, change your value of $url to:
$url="http://www.myremotesite.com/postlogin.php";
Verify the values you have listed in $postdata:
$postdata = "email=".$username."&password=".$password;
and it should work just fine.

This is how I solved this in ImpressPages:
//initial request with login data
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.php');
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "username=XXXXX&password=XXXXX");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie-name'); //could be empty, but cause problems on some hosts
curl_setopt($ch, CURLOPT_COOKIEFILE, '/var/www/ip4.x/file/tmp'); //could be empty, but cause problems on some hosts
$answer = curl_exec($ch);
if (curl_error($ch)) {
echo curl_error($ch);
}
//another request preserving the session
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/profile');
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, "");
$answer = curl_exec($ch);
if (curl_error($ch)) {
echo curl_error($ch);
}

Panama Jack Example not work for me - Give Fatal error: Call to undefined function build_unique_path(). I used this code - (more simple - my opinion) :
