geary's Issues

Callback

Hello, how I ca check the order status with the callback?

I am trying to implement your geary into my store.
So I have the problem that the page stops working with Callback response status: 500
I could trace down the issue to $order = $geary->check_order_callback();
Then I tried to use you Check order status from Gear's webhook example 1:1 and still getting this error you got an idea why.

Regards Artur

I have a problem, the code does not work, or I do something wrong.

Hello. If I use a class without changing anything, I always get a response error 400

Error: <html>
<head><title>400 Bad Request</title></head>
<body bgcolor="white">
<center><h1>400 Bad Request</h1></center>
<hr><center>nginx/1.8.0</center>
</body>
</html>

If I change the method and send the parameters as in example 3 of the documentation on the site, I always get an error that the signature is not correct

slightly changed the code

	$data = array("amount" => "1", "keychain_id" => "1");                                                                    
	$data_string = json_encode($data);

        $curl_data = array(
            CURLOPT_URL             => $url,
            CURLOPT_RETURNTRANSFER  => TRUE,

    }

I get the result:

if I use the data from Example 3 on the site https://admin.gear.mycelium.com/docs/api/signed_request

secret = '5ioHLiVwxqkS6Hfdev8pNQfhA9xy7dK957RBVYycMhfet23BTuGUPbYxA9TP6x9P'
nonce = 1442215362723
body = '{"amount":1,"keychain_id":1}'

I get the same signatures that are specified in the example, so the algorithm works correctly, if my data, I always get X-Signature is invalid.

I generated the secret key several times and nothing helped. Site support is not responding.
Thank you for your work, I hope for your help.

checkOrderCallback does not work

The signatures never match. I guess the bug is somewhere in the code that calculates the signature before comparing it.

Use composer

Hello.
Can I use your class through a composer?

Issues with nginx / php-fpm

getallheaders() is not available on nginx. Fixed that with:

        if (!function_exists('getallheaders')) {
            function getallheaders()
            {
                $headers = [];
                foreach ($_SERVER as $name => $value) {
                    if (substr($name, 0, 5) == 'HTTP_') {
                        $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
                    }
                }
                return $headers;
            }
        }

Undefined index: REDIRECT_URL in Geary.php on line 110

This is also only set by Apache. REQUEST_URI would be better

check_order_callback and after payment redirect gives signature mismatch

When mycelium gear makes the call back and you have an 'after payment redirect url' set, it will give a signature mismatch as mycelium urlencodes the enter you put in as the after payment redirect.

How do I send additional data? (callback_data)

Is there a function/parameter to send additional data when creating an order? Called callback_data in their API.
