VK Communities: how to send a message with a photo?

Question

PHP

Good time of the day!
I need to send a message on behalf of the community with a photo attachment. To do this, you must first upload a photo, such as this request:

$token = 'XXX';
$group_id = '162294758';
$album_id = '162294758';
$v = '5.64'; //версия vk api
$image_path = "http://worldwideshop.ru/vbot-dev/api/test.jpg"; //путь до картинки
$fp = fopen($image_path, 'r');

// получаем урл для загрузки
$url = file_get_contents("https://api.vk.com/method/photos.getUploadServer?album_id=".$album_id."&group_id=".$group_id."&v=".$v."&access_token=".$token);
$url = json_decode($url)->response->upload_url;
print_r($url);

// отправка post картинки
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_INFILE, $fp);
$result = json_decode(curl_exec($ch),true);
print_r($result);

// сохраняем
$safe = file_get_contents("https://api.vk.com/method/photos.save?server=".$result['server']."&photos_list=".$result['photos_list']."&album_id=".$result['aid']."&hash=".$result['hash']."&gid=".$group_id."&access_token=".$token);
$safe = json_decode($safe,true);
print_r($safe);

Array ( [error] => Array ( [error_code] => 5 [error_msg] => User authorization failed: method is unavailable with group auth. [request_params] => Array ( [0] => Array ( [key] => oauth [value] => 1 ) [1] => Array ( [key] => method [value] => photos.save ) [2] => Array ( [key] => server [value] => ) [ 3] => Array ( [key] => photos_list [value] => ) [4] => Array ( [key] => album_id [value] => ) [5] => Array ( [key] => hash [value] => ) [6] => Array ( [key] => gid [value] => 162294758 ) ) ) )

Questions:

1. Where is the right place to upload this photo initially? If in a community album, should it be public?
   
2. Tell me a simple example for downloading an attachment (on the net or ready-made large solutions or old non-working pieces of code, such as links to git here ).
   

Answer 1

0. You can’t post your token in the public domain like this! We hope he is already disabled.
1. To upload photos to the dialog, you need to use special methods:
https://vk.com/dev/photos.getMessagesUploadServer
https://vk.com/dev/photos.saveMessagesPhoto
2. The version parameter v is missing in the second request, and it is required in any request.
