How to generate QuickBlox authentication signature in PHP? - api

Question

I want to access the APIs in QuickBlox, but before that we need to authenticate our apps and get a session token, and using session token we can access the other APIs.
But the problem is, when I send the authentication request using the required specification given on the QuickBloxwebsite, I am getting the error message:
{"errors":{"base":["Unexpected signature"]}}
The parameters to generate the signature is:
application_id=22&auth_key=wJHd4cQSxpQGWx5&nonce=33432&timestamp=1326966962
And then we convert it in HMAC-SHA format:
hash_hmac( 'sha1', $signatureStr , $authSecret);
Please help me to resolve this problem.

Answer 1

I wrote code snippet on php, it generates signature. It works good
this is my test application's credentials:
$application_id = 92;
$auth_key = "wJHdOcQSxXQGWx5";
$authSecret = "BTFsj7Rtt27DAmT";
$nonce = rand();
echo "<br>nonce: " . $nonce;
$timestamp = time();
echo "<br>timestamp: " . $timestamp ."<br>";
$stringForSignature = "application_id=".$application_id."&auth_key=".$auth_key."&nonce=".$nonce."&timestamp=".$timestamp;
echo $stringForSignature."<br>";
$signature = hash_hmac( 'sha1', $stringForSignature , $authSecret);
echo $signature;
hope this help

Problem solved
There was a problem in my request parameters.
$params = "application_id=$application_id&auth_key=$auth_key&timestamp=$timestamp&nonce=$nonce&signature=$signature&**auth_secret=$authSecret**";
In this parameter I was passing an extra parameter, my auth secret key which should not be there. I removed this parameter and now its working.

Here is full example how to create QuickBlox session:
<?php
// Application credentials
DEFINE('APPLICATION_ID', 92);
DEFINE('AUTH_KEY', "wJHdOcQSxXQGWx5");
DEFINE('AUTH_SECRET', "BTFsj7Rtt27DAmT");
// User credentials
DEFINE('USER_LOGIN', "emma");
DEFINE('USER_PASSWORD', "emma");
// Quickblox endpoints
DEFINE('QB_API_ENDPOINT', "https://api.quickblox.com");
DEFINE('QB_PATH_SESSION', "session.json");
// Generate signature
$nonce = rand();
$timestamp = time(); // time() method must return current timestamp in UTC but seems like hi is return timestamp in current time zone
$signature_string = "application_id=".APPLICATION_ID."&auth_key=".AUTH_KEY."&nonce=".$nonce."&timestamp=".$timestamp."&user[login]=".USER_LOGIN."&user[password]=".USER_PASSWORD;
echo "stringForSignature: " . $signature_string . "<br><br>";
$signature = hash_hmac('sha1', $signature_string , AUTH_SECRET);
// Build post body
$post_body = http_build_query(array(
'application_id' => APPLICATION_ID,
'auth_key' => AUTH_KEY,
'timestamp' => $timestamp,
'nonce' => $nonce,
'signature' => $signature,
'user[login]' => USER_LOGIN,
'user[password]' => USER_PASSWORD
));
// $post_body = "application_id=" . APPLICATION_ID . "&auth_key=" . AUTH_KEY . "&timestamp=" . $timestamp . "&nonce=" . $nonce . "&signature=" . $signature . "&user[login]=" . USER_LOGIN . "&user[password]=" . USER_PASSWORD;
echo "postBody: " . $post_body . "<br><br>";
// Configure cURL
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, QB_API_ENDPOINT . '/' . QB_PATH_SESSION); // Full path is - https://api.quickblox.com/session.json
curl_setopt($curl, CURLOPT_POST, true); // Use POST
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_body); // Setup post body
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); // Receive server response
// Execute request and read responce
$responce = curl_exec($curl);
// Check errors
if ($responce) {
echo $responce . "\n";
} else {
$error = curl_error($curl). '(' .curl_errno($curl). ')';
echo $error . "\n";
}
// Close connection
curl_close($curl);
?>

Answer 4

You have to use your own application parameters:
application_id
auth_key
and random 'nonce' and current timestamp (not from example, you can get current timestamp on this site http://www.unixtimestamp.com/index.php)
Your code is right, but you must set proper parameters

Answer 5

1) You should send request to correct url.
to
https://api.quickblox.com/auth.json
instead
https://api.quickblox.com/session.json
2) You should fix SSL problem using this.
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false)

Answer 6

We use php, and next code works well for us:
<?php
$userLogin = '{YOUR_QB_USER}';
$userPassword = '{YOUR_QB_PASSWORD}';
$body = [
'application_id' => '{YOUR_QB_APPLICATION_ID}',
'auth_key' => '{YOUR_QB_AUTH_KEY}',
'nonce' => time(),
'timestamp' => time(),
'user' => ['login' => $userLogin, 'password' => $userPassword]
];
$built_query = urldecode(http_build_query($body));
$signature = hash_hmac('sha1', $built_query , '{YOUR_QB_APP_SECRET}');
$body['signature'] = $signature;
$post_body = http_build_query($body);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'https://{YOUR_QB_HOST}/session.json');
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_body);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl);
$token = json_decode($response, true)['session']['token'];
printf('Your token is: %s %s', $token, PHP_EOL);
