如何使用 php youtube-api 为视频上传自定义缩略图。

我尝试使用 Zend 框架进行 youtube 直接视频上传，它正在工作，但我找不到任何自定义缩略图上传方法..

我尝试了以下代码

 $parms = array('videoId => '' ,mediaUpload => '');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.googleapis.com/upload/youtube/v3/thumbnails/set/');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $parms);
curl_setopt($ch, CURLOPT_HTTPHEADER, array( "Content-Type: image/jpeg", 'Authorization: Bearer '.$token['access_token']));
$return = json_decode(curl_exec($ch));

error thrown

   }
  ],

}

您可以将PHP 客户端库用于Data API v3。Zend 用于 GData，较旧的 API。

您可以使用此示例上传自定义缩略图。请记住，您应该有适当的权限让您的频道上传自定义缩略图。

// Call set_include_path() as needed to point to your client library.
require_once 'Google_Client.php';
require_once 'contrib/Google_YouTubeService.php';
session_start();

/* You can acquire an OAuth 2 ID/secret pair from the API Access tab on the Google APIs Console
 <http://code.google.com/apis/console#access>
For more information about using OAuth2 to access Google APIs, please visit:
<https://developers.google.com/accounts/docs/OAuth2>
Please ensure that you have enabled the YouTube Data API for your project. */
$OAUTH2_CLIENT_ID = 'REPLACE_ME';
$OAUTH2_CLIENT_SECRET = 'REPLACE_ME';

$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],
    FILTER_SANITIZE_URL);
$client->setRedirectUri($redirect);

// YouTube object used to make all Data API requests.
$youtube = new Google_YoutubeService($client);

if (isset($_GET['code'])) {
  if (strval($_SESSION['state']) !== strval($_GET['state'])) {
    die('The session state did not match.');
  }

  $client->authenticate();
  $_SESSION['token'] = $client->getAccessToken();
  header('Location: ' . $redirect);
}

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

// Check if access token successfully acquired
if ($client->getAccessToken()) {
  try{

    // REPLACE with the channel that you want to upload into
    $videoId = "VIDEO_ID";

    // REPLACE with the path to your file that you want to upload for thumbnail
    $imagePath = "/path/to/file.png";

    // Size of each chunk of data in bytes. Setting it higher leads faster upload (less chunks,
    // for reliable connections). Setting it lower leads better recovery (fine-grained chunks)
    $chunkSizeBytes = 1 * 1024 * 1024;

    // Create a MediaFileUpload with resumable uploads
    $media = new Google_MediaFileUpload('image/png', null, true, $chunkSizeBytes);
    $media->setFileSize(filesize($imagePath));

    // List associated content owners to get content owner id
    $setResponse = $youtube->thumbnails->set($videoId, array('mediaUpload' => $media));

    $uploadStatus = false;

    // Read file and upload chunk by chunk
    $handle = fopen($imagePath, "rb");
    while (!$uploadStatus && !feof($handle)) {
      $chunk = fread($handle, $chunkSizeBytes);
      $uploadStatus = $media->nextChunk($setResponse, $chunk);
    }

    fclose($handle);

    $thumbnailUrl = $uploadStatus['items'][0]['default']['url'];
    $htmlBody .= "<h3>Thumbnail Uploaded</h3><ul>";
    $htmlBody .= sprintf('<li>%s (%s)</li>',
        $videoId,
        $thumbnailUrl);
    $htmlBody .= sprintf('<img src="%s">', $thumbnailUrl);
    $htmlBody .= '</ul>';


    } catch (Google_ServiceException $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;
    }

  //CONVERT IMAGE FROM URL AND STORE
    $randomstr = generateRandomString();
    $thumbnail_url = "http://i.ytimg.com/vi/BMFLzf-DXXU/hqdefault.jpg";   
    $ch = curl_init($thumbnail_url);
    $fp = fopen('videos/'.$randomstr.'.jpg', 'wb');
    curl_setopt($ch, CURLOPT_FILE, $fp);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_exec($ch);
    curl_close($ch);
    fclose($fp);

与输出状态一样，您需要提供要为其上传缩略图的视频的“videoId”。这是一个必需的参数。

缺少视频 ID。先上传视频，然后使用 videoId 为上传的视频创建缩略图
