如何上传文件public，DOWNLOADING未经授权可用？

Question

I upload file like this:

    if (isset($_FILES[$name])) {
        $service = new Google_DriveService($client);

        //Insert a file
        $file = new Google_DriveFile();
        $file->setTitle($_FILES[$name]['name']);
        $file->setMimeType($_FILES[$name]['type']);
        $file->setParents(array('imgs'));

        $insertedFile = $service->files->insert($file, array(
            'data' => file_get_contents($_FILES[$name]['tmp_name']),
            'mimeType' => $_FILES[$name]['type']
        ));

        return $insertedFile;
    }

Get insertedFile as this:

Array
(
    [kind] => drive#file
    [id] => 1sASTlgG7IFzcZyTUihp53uJbppFtxLs_GK_V2jYwapE
    [etag] => "vGmlhiWxP02tugPmRvLynwC_A0Y/MTM2NjE4NTYyNzQwOQ"
    [selfLink] => https://www.googleapis.com/drive/v2/files/1sASTlgG7IFzcZyTUihp53uJbppFtxLs_GK_V2jYwapE
    [alternateLink] => ...

But when i go to selfLink, i get an error

{
  ...
  "code": 403,
  "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
 }
}

What is the correct way to get uploaded file without any kind of authorization? Looks like file is only available through the API.

If you want to download the content, make an authenticated request to the download URL.

// Get the contents of the file.
$request = new Google_HttpRequest($file->downloadUrl);
$response = $client->getIo()->authenticatedRequest($request);
$content = $response->getResponseBody();
