VK API, PHP How to get a token that has enough rights for the wall.post method?

Question

PHP

Good afternoon!
The essence of the task is to make a post on the wall of the current user from the site.
I have a standalone application, with its ID I redirect to authorize, I get code. By code I get access_token. Of course I request the rights of wall. When requesting wall.post, I get the 15th error Access denied: no access to call this method. When I receive the code, I substitute my base domain in the redirect_url, if I substitute the vk blank domain, then this method starts working.
The problem lies in the fact that substituting the vk domain does not make it easier for me. I can’t get a token and make a post.
Question - how to be? What is the algorithm for obtaining such a token so that I can authorize the user and make posts on his wall on his behalf?

Answer 1

For sites, access to the wall is limited. You should do authorization on the site through the Open API and then you can only make entries through the confirmation window .

Answer 2

I have a standalone app

standalone are desktop programs (not websites). and this mode is not accidentally made so that it is impossible to get tokens for sites.
There is only one way - to send users to follow the link with redirect_url=vk blank and copy the token from there. Yes, they will see a warning that it is impossible to copy, and many will not do this and will do it right.
to make entries on the user's wall, the token is not needed - the usual share button - the user himself shares.
if you allow all sites access to the wall, then very quickly it will be polluted by all and sundry.
