curl_close ($ch);
echo $result;

Is there any error? I'm doing something wrong, but i can not find it. please let me know if you can see where is my error? i need to set up this curl class.


The POST data is malformed, it should be :
[...] "login=" . urlencode($php_userid). "&passwd=" . urlencode($php_password) . ""
Instead of
[...] "login".$php_userid."&passwd".$php_password.""
You should use urlencode to ensure that the data passed in POST data is properly sent and you where missing an = for the login and passwd value.


You should use curl_error to determine what is failing during the cURL process. You can see a list of cURL error codes here: http://curl.haxx.se/libcurl/c/libcurl-errors.html
$result = curl_exec($ch);
$error = curl_error($ch);
print $error;
curl_close ($ch);


I assume the .challenge field gets dynamically generated. Your curl request uses an invalid challenge and so the server blocks it.


$cookie = cookie.txt";
Insert after: curl_setopt($ch, CURLOPT_POSTFIELDS,$POSTFIELDS); this: curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);

Logging into secure site using CURL [duplicate]

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.

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?
And one useful related question. About how to keep a session alive in cUrl: https://stackoverflow.com/a/13020494/2226796

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);
}

PHP Curl does not return a values from url

i am using above function to retrieve the two urls , second one works when i am retriving google or other websites, but below things is not getting any response. but when i enter the url in browser i am seeing the response.. can you guide me to fix this issue?
function file_get_contents_curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$response=file_get_contents_curl('http://XX.XX.XX.XX:YYYYY/Request?Mob=999999999&Message=Rr+vodafone+999999999+10+1234&myTxId=10');
echo "<br/>respnse is...".$response;
$response=file_get_contents_curl('http://www.google.com');
echo "<br/>website respond is...".$response;
Edit:
Issue is with Port number i am trying to access 8090 is not enabled in my server. when i enabled it for outgoing it was working... Thanks every one for the support.

Can you try:
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 5.1; rv:12.0) Gecko/20100101 Firefox/12.0');

Try to find error give this code before curl close:--
echo "Curl Error :--" . curl_error($ch);
if no error found do like this:-
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
then
print_r($result);
exit;

CURL - cookie not enabled/session expired

I am trying to log into a website using PHP CURL. It all works fine on websites which doesn't require cookies and session but it doesn't seem to work with the websites which rquire you so here is my code I found this code over here
any help on this would be apritiated thanks
Code
<?php
// 1-Get First Login Page http://signin.ebay.com/aw-cgi/eBayISAPI.dll?SignIn
$ebay_user_id = "username"; // Please set your Ebay ID
$ebay_user_password = "password"; // Please set your Ebay Password
$cookie_file_path = "cookie.txt"; // Please set your Cookie File path
$LOGINURL = "__";
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$LOGINURL);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
$result = curl_exec ($ch);
// curl_close ($ch);
print $result;
?>

Maybe you need more options:
// define some HTTP headers
$headers[] = "Accept: */*";
$headers[] = "Connection: Keep-Alive";
$headers[] = "Content-type: application/x-www-form-urlencoded;charset=UTF-8";
// to GET add
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// to POST add
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 1);
// check for errors before close
$result = curl_exec($ch);
if ($result === false)
{
echo curl_error($ch);
}
curl_close($ch);
Be sure that your $cookie_file_path file is writable (if Linux). Play with CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER.

http://signin.ebay.com/aw-cgi/eBayISAPI.dll not only expects username and password as post data, but other parameters as well, maybe you didn't take account of that. Use Net tab on firebug to see the parameters passed, and try to duplicate it.

SMF curl login issue php

Does any one have have some PHP login curl code for SMF version 1.1.11
I tried and it logs then when I check the curl output, but when the broswer loads, they are no longer logged in
My code
function login($data)
{
if(function_exists('curl_init' )) {
$_SESSION['old_url'] = $_SERVER['HTTP_HOST'] .'test';
// smf needs this sigh
// create a new cURL resource
$data = array( 'noverify'=>1 , 'user'=> $data['username'] , 'passwrd' => $data['password'] ,'hash_passwrd'=>$data['password'], 'cookielength'=>'60');
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $_SERVER['HTTP_HOST'] . "/forum/index.php?action=login2");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_HEADER, 0);
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__).'/cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__).'/cookie.txt');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
// grab URL and pass it to the browser
$a = curl_exec($ch);
//$ch_temp=curl_copy_handle($ch);
//print_r($ch_temp);
// close cURL resource, and free up system resources
curl_close ($ch);
}
}

That's to be expected. Your script and your browser do not use the same cookie. It's like if you logged in with Firefox and expected that when you open Chrome you'll be logged in as well.
