How to get access_token vkontakte oauth2?

Question

PHP

Application in the form of a website.
I do authorization as per the guide I
stop to receive a token writes:

{"error":"invalid_grant","error_description":"Code is invalid or expired."}

My link:

https://oauth.vk.com/access_token?client_id=мойид&client_secret=мойключ&redirect_uri=мойурл&code=257db363d39654cac7

I googled all over and couldn't find an answer. Tell me what's the problem.

Answer 1

That's how my problem was solved.
In general, the situation is this, you need to go to http to get the code, not https.

Answer 2

Why don't you use Auth Widget ?
// EDIT
If there are problems in the server part:
1) check the settings of the VK application (callback url, etc.)
2) check the links that you generate

Answer 3

It looks like a new code has already been received,
so the request contains the old one, which is what it swears at.
You need to try to get the code again using the link
https://oauth.vk.com/authorize?client_id=1&display...
