YouTube API v3 - 直接上传到自己的频道

Question

由于 YouTube v2 API 即将弃用，我需要迁移到 v3。

对于 v2，我使用同样已弃用的 ClientLogin (http://bit.ly/v2_ClientLogin_authentification) 身份验证方法进行身份验证，然后将用户视频上传到我的 YouTube 频道。

对于 v3，我尝试使用 服务帐户 进行身份验证，这里使用的是相同的代码库

PHP Youtube API v3 - Direct Upload - Unauthorized message

并且我从 API 端点收到相同的错误消息：

Error calling POST https://www.googleapis.com/youtube/v3/videos?part=status%2Csnippet: (401) Unauthorized

我也通过Google的令牌信息进行了检查 (https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=[ACCESS_TOKEN]) 访问令牌有效：

{
 "issued_to": "***.apps.googleusercontent.com",
 "audience": "***.apps.googleusercontent.com",
 "scope": "https://www.googleapis.com/auth/youtube",
 "expires_in": 3592,
 "access_type": "offline"
}

我找到的所有 YouTube 示例均基于 OAuth2 和用户授权。（就像这里的这个：http://bit.ly/yt-api-example-videoupload）。但这不是我想要的方式：用户不应该看到任何 "Please authorize whatever.de to upload YouTube videos" AND 视频应该上传到我的 YT 频道而不是他们的。

如果无法为此使用 API 服务帐户，您能否提示我如何使用 OAuth2 执行此操作？ :-)

这是我当前的代码：

/** Config */ 
$private_key_password = 'notasecret';
$private_key_file = '***.p12';
$applicationName = '***';
$client_secret = '***'; // <--- WHERE IS THAT CLIENT_SECRET COMING FROM? Secret accounts do not have a client secret? 
$client_id = '***.apps.googleusercontent.com';
$service_mail = '***@developer.gserviceaccount.com';

$scope = 'https://www.googleapis.com/auth/youtube';
$url_youtube_token = 'https://accounts.google.com/o/oauth2/token';

$jwt = new Google_Auth_AssertionCredentials($service_mail, $scope, $private_key_file, $private_key_password, $url_youtube_token);
$jwt_assertion = $jwt->generateAssertion();

$data = array
(
    'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer',
    'assertion' => $jwt_assertion,
);

$options = array
(
    'http' => array
    (
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data),
    ),
);

$context = stream_context_create($options);
$result = file_get_contents($url_youtube_token, false, $context);

//var_dump($result); die();

try{
    // Client init
    $client = new Google_Client();
    $client->setClientId($client_id);
    //$client->setClientSecret($client_secret); // <-- See above
    $client->setApplicationName($applicationName);

    $client->setAccessToken($result);

    if ($client->getAccessToken()) 
    {
        if($client->isAccessTokenExpired()) 
        {
            // @TODO Log error
            echo 'Access Token Expired!!<br/>'; // Debug
        }

        $youtube = new Google_Service_Youtube($client);

        $videoPath = "./test.mp4";

        // Create a snipet with title, description, tags and category id
        $snippet = new Google_Service_YouTube_VideoSnippet();
        $snippet->setTitle("fmgonzalez test " . time());
        $snippet->setDescription("fmgonzalez test " . time() );
        $snippet->setTags(array("tag1", "tag2"));

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

        // Create a video status with privacy status. Options are "public", "private" and "unlisted".
        $status = new Google_Service_YouTube_VideoStatus();
        $status->privacyStatus = "public";

        // Create a YouTube video with snippet and status
        $video = new Google_Service_YouTube_Video();
        $video->setSnippet($snippet);
        $video->setStatus($status);

        // 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
        $insertRequest = $youtube->videos->insert("status,snippet", $video);

        $media = new Google_Http_MediaFileUpload
        (
            $client,
            $insertRequest,
            'video/*',
            null,
            true,
            $chunkSizeBytes
        );

        $media->setFileSize(filesize($videoPath));

        // Create a video insert request
        $insertResponse = $youtube->videos->insert("status,snippet", $video,
            array('mediaUpload' => $media));

        $uploadStatus = false;

        // Read file and upload chunk by chunk
        $handle = fopen($videoPath, "rb");
        $cont = 1;
        while (!$uploadStatus && !feof($handle)) 
        {
            $chunk = fread($handle, $chunkSizeBytes);
            $uploadStatus = $media->nextChunk($insertResponse, $chunk);
            echo 'Chunk ' . $cont . ' uploaded <br/>';
            $cont++;
        }

        fclose($handle);

        echo '<br/>OK<br/>';

    }
    else
    {
        // @TODO Log error
        echo 'Problems creating the client';
    }

无法使用服务帐户访问 YouTube API

Issue 5370: Youtube v3 Google Service Account Access

您将需要使用 Oauth2您只需要验证一次。使用离线访问保存您的刷新令牌。然后您可以将其用于运行您的脚本。

$client->setAccessType('offline');   // Gets us our refreshtoken
