How to upload an image to your server?

Question

PHP

Hello!
I am writing authorization through Google and it became necessary to upload the user's avatar to my server.
Google sends me a response that has a link to the avatar:

"picture": "https://lh6.googleusercontent.com/-sdKkMmClA5M/BABBBBBBDI/AAAAABAAAQg/4SjnUI7UOsQ/s96-c/photo.jpg"

I'm uploading her trail. way

$picture = $token_info['picture'];
$sourcecode=GetImageFromUrl($picture);
$savefile = fopen('/var/www/html/uploads/avatars/image.jpg', 'w');
fwrite($savefile, $sourcecode);
fclose($savefile);

function GetImageFromUrl($link) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch,CURLOPT_URL,$link);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result=curl_exec($ch);
curl_close($ch);
return $result;
}

When uploading, an error occurs in the logs:
fopen(): failed to open stream: Permission denied
Apparently there are problems with access rights to the folder where I download the file. I read this article and added the www-data user to my group, which I assigned the rights to:

sudo usermod -a -G user_main www-data
sudo chmod -R 750 /var/www/html/uploads/avatars/

But after doing that, the server now throws a 403 error:

You don't have permission to access /upload_avatar on this server.

Advise how to properly upload files to your server. Maybe there is an article or an example?

Answer 1

I don’t know how you have everything set up there, but you can try to do the following:

Allow access to your server files
Open the apache2.conf file located at
Locate the line "Directory /var/www/" and write the following

<Directory /var/www/>
  Options Indexes FollowSymLinks
  AllowOverride All	
  Allow From All
  Require all granted
</Directory>

Restarted Apache
Everything should work

Answer 2

fopen(): failed to open stream: Permission denied
is an error due to the fact that Google gives a 404 error on the link to the photo, Not Found (image not found)
and then you have to play with the rights, put 777 for sure)

If that doesn't work, it's obviously a permissions issue. This is already a separate issue.
