Why can't I log in to a contact?

Question

PHP

I am writing a script for authorizing applications in a contact based on https://github.com/speechkey/VKAppAuth. I stumbled at the authorization stage. In theory, I should redirect to a link to allow access to the application, but instead I get a link to re-authorize.
Here is the code itself: https://github.com/matperez/vk-app-auth/blob/maste... .
Before sending $authRequest, I receive from the authorization form a link " https://login.vk.com/?act=login&soft=1&utf8=1 " and a set of parameters:

[
            '_origin' => 'https://oauth.vk.com',
            'ip_h' => '8e29e63c00c0ca4f20',
            'lg_h' => '1b2c06197b914831c8',
            'to' => 'aHR0cHM6Ly9vYXV0aC52ay5jb20vYXV0aG9yaXplP2NsaWVudF9pZD0zNzEzNzc0JnJlZGlyZWN0X3VyaT1odHRwcyUzQSUyRiUyRm9hdXRoLnZrLmNvbSUyRmJsYW5rLmh0bWwmcmVzcG9uc2VfdHlwZT10b2tlbiZzY29wZT04JnY9JnN0YXRlPSZkaXNwbGF5PXdhcA--',
        ]

I add the username and password there, and send a post request to the server. The server should redirect to the page with permission. Instead, I get a re-authorization link. What am I not doing wrong? Maybe the point is that some necessary cookies are set on the authorization page through Javascript?

Answer 1

Understood. By mistake did not store cookies in the request. The process itself is correct and working.
