Vk.api, wall.post on a third party site

Question

API

There is a site, I want to post messages on the wall of groups from users from it.
Created a standalone application. I got a token, but when I call wall.post I get an error:
"Permission to perform this action is denied for non-standalone applications: you should request token using blank.html page"
If I specify https://oauth.vk in the redirect. com/blank.html, then the application will not be able to parse the token.
How to get around this problem? For example, http://buzzlike.ru/ somehow posts messages.

Answer 1

If I specify https://oauth.vk.com/blank.html in the redirect , then the application will not be able to parse the token.

Why don't you parse it?
Here is a working php example

$cl = new HTTP_Client;
$cl->setDefaultHeader("Accept-Encoding", "identity");
$cl->get("https://oauth.vk.com/authorize?client_id=xxx&scope=video,groups,photos,wall,offline&display=wap&redirect_uri=https://oauth.vk.com/blank.html&response_type=token"); 

$resp = $cl->currentResponse();

$dom = str_get_dom($resp['body']);
$postData = array();
foreach ($dom->find("input") as $input)
{
  if ($input->name)
  {
    $postData[$input->name] = $input->value;
  }
}
$postData['email'] = $urow['login'];
$postData['pass'] = $urow['pass'];
$postData['expire'] = '0';

$cl->post($dom->find("form", 0)->action, $postData);
$resp = $cl->currentResponse();
if (strstr($resp['url'], "oauth.vk.com/blank.htm"))
{
  $oauth_success_url = $resp['url'];
}
else
{
  $dom->__destruct();
  unset($dom);
  $dom = str_get_dom($resp['body']);
  $cl->get($dom->find("form", 0)->action);
  $resp = $cl->currentResponse();
  $oauth_success_url = $resp['url'];
}
if (!preg_match("#access_token=([0-9a-f]+)&#", $oauth_success_url, $m))
{
  printf("Не удалось авторизоваться vk\n");
  exit(1);
}
$access_token = $m[1];
echo $access_token."\r\n";

Write to the administration or one of the developers, they will issue permission if you justify the need well, otherwise nothing.
ps we solved this issue personally through Vlad Tsyplukhin
