PHP + Youtube API - how to allow user to upload videos to my own channel?

I am trying to build a web app that allows users to upload videos to my channel.

So I think I must go for OAuth 2.0 for Server to Server Applications, just as it says it there:

Typically, an application uses a service account when the application uses Google APIs to work with its own data rather than a user's data.

So I have followed the steps to create a service account. But after completing the steps and have the key and id generated, I got an error below:

An client error occurred: Failed to start the resumable upload (HTTP 401: youtube.header, Unauthorized)

This is my entire code:

// Load 'Google/Client.php' and 'Google/Service/YouTube.php' with composer.
require_once __DIR__ . '/vendor/autoload.php';
session_start();

$client_email = '[email protected]';
$private_key = file_get_contents('xxx-74c6a50933e3.p12');
$scopes = array(
  'https://www.googleapis.com/auth/youtube.upload',
  'https://www.googleapis.com/auth/youtube',
  'https://www.googleapis.com/auth/youtubepartner'
);

$credentials = new Google_Auth_AssertionCredentials(
    $client_email,
    $scopes,
    $private_key
);

$client = new Google_Client();
$client->setAssertionCredentials($credentials);
if ($client->getAuth()->isAccessTokenExpired()) {
     $client->getAuth()->refreshTokenWithAssertion();
}

$htmlBody = '';

// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);

$htmlBody = '';

// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
  try{
    // REPLACE this value with the path to the file you are uploading.
    $videoPath = "/home/xxx/Desktop/Vids/small.mp4";

    // Create a snippet with title, description, tags and category ID
    // Create an asset resource and set its snippet metadata and type.
    // This example sets the video's title, description, keyword tags, and
    // video category.
    $snippet = new Google_Service_YouTube_VideoSnippet();
    $snippet->setTitle("Test title");
    $snippet->setDescription("Test description");
    $snippet->setTags(array("tag1", "tag2"));

    // Numeric video category. See
    // https://developers.google.com/youtube/v3/docs/videoCategories/list
    $snippet->setCategoryId("22");

    // Set the video's status to "public". Valid statuses are "public",
    // "private" and "unlisted".
    $status = new Google_Service_YouTube_VideoStatus();
    $status->privacyStatus = "public";

    // Associate the snippet and status objects with a new video resource.
    $video = new Google_Service_YouTube_Video();
    $video->setSnippet($snippet);
    $video->setStatus($status);

    // Specify the size of each chunk of data, in bytes. Set a higher value for
    // reliable connection as fewer chunks lead to faster uploads. Set a lower
    // value for better recovery on less reliable connections.
    $chunkSizeBytes = 1 * 1024 * 1024;

    // Setting the defer flag to true tells the client to return a request which can be called
    // with ->execute(); instead of making the API call immediately.
    $client->setDefer(true);

    // Create a request for the API's videos.insert method to create and upload the video.
    $insertRequest = $youtube->videos->insert("status,snippet", $video);

    // Create a MediaFileUpload object for resumable uploads.
    $media = new Google_Http_MediaFileUpload(
        $client,
        $insertRequest,
        'video/*',
        null,
        true,
        $chunkSizeBytes
    );
    $media->setFileSize(filesize($videoPath));


    // Read the media file and upload it chunk by chunk.
    $status = false;
    $handle = fopen($videoPath, "rb");
    while (!$status && !feof($handle)) {
      $chunk = fread($handle, $chunkSizeBytes);
      $status = $media->nextChunk($chunk);
    }

    fclose($handle);

    // If you want to make other calls after the file upload, set setDefer back to false
    $client->setDefer(false);


    $htmlBody .= "<h3>Video Uploaded</h3><ul>";
    $htmlBody .= sprintf('<li>%s (%s)</li>',
        $status['snippet']['title'],
        $status['id']);

    $htmlBody .= '</ul>';

  } catch (Google_Service_Exception $e) {
    $htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
        htmlspecialchars($e->getMessage()));
  } catch (Google_Exception $e) {
    $htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
        htmlspecialchars($e->getMessage()));
  }

  $_SESSION['token'] = $client->getAccessToken();
} else {
  // If the user hasn't authorized the app, initiate the OAuth flow
  $state = mt_rand();
  $client->setState($state);
  $_SESSION['state'] = $state;

  $authUrl = $client->createAuthUrl();
  $htmlBody = <<<END
  <h3>Authorization Required</h3>
  <p>You need to <a href="$authUrl">authorize access</a> before proceeding.<p>
END;
}
?>

<!doctype html>
<html>
<head>
<title>Video Uploaded</title>
</head>
<body>
  <?=$htmlBody?>
</body>
</html>

Any ideas what have I missed?

I think I found the answer from this article.

Steps:

Step 1. Create a token.php (make sure set it to 777). Place the code example from Google - https://developers.google.com/youtube/v3/code_samples/php#upload_a_video - with a little of this modification as follow:

Change:

if (isset($_SESSION['token'])) {
  $client->setAccessToken($_SESSION['token']);
}

To:

if (isset($_SESSION['token'])) {
  $client->setAccessToken($_SESSION['token']);

  // @ref: http://www.whitewareweb.com/php-youtube-video-upload-google-api-oauth-2-0-v3/
  echo "Access Token: " . $_SESSION['token'];
}

Step 2. Run token.php on your browser. Grant the access. Then you get a json output below:

{
  "access_token": "xxxxt7YvjObwYx3DG4NRmfjiQ",
  "token_type": "Bearer",
  "expires_in": 3600,
  "refresh_token": "xxxxq5hzQTUapZ7zyRIHP7X_G8",
  "created": 1466238624
}

Save it as token.txt

Step 3. Create upload.php with the same example code from Google - with the following modification:

One. Include token.txt file in the beginning of your upload.php:

$key = file_get_contents('token.txt');

Then pass $key into new Google_Client():

$OAUTH2_CLIENT_ID = 'xxxx.googleusercontent.com';
$OAUTH2_CLIENT_SECRET = 'xxxx';

// Client init
$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$client->setAccessToken($key);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);

Two. Add this code in the try catch section before $youtube = new Google_Service_YouTube($client);:

    /**
     * Check to see if our access token has expired. If so, get a new one and save it to file for future use.
     */
    if($client->isAccessTokenExpired()) {
        $newToken = json_decode($client->getAccessToken());
        $client->refreshToken($newToken->refresh_token);
        file_put_contents('token.txt', $client->getAccessToken());
    }

Step 4. Run upload.php that's it.

You can get the entire code from that article.

I know this sounds pretty weird, but I had the same issue the other day. I was trying different things... Try to change the YouTube category ID...

Try to change it to 1, took me hours of troubleshooting this to finally find that a lot of the categories do not work in the YouTube PHP SDK.

If that works, might want to make an API call to YouTube and get a list of all Category ID's, and try them all individually until you find the ones that do work... Documentation on how to do that is here: https://developers.google.com/youtube/v3/docs/videoCategories/list

This is assuming that you have all of your OAuth tokens correct.
