Question

由于YouTube v2 API已弃用，我需要迁移到v3。

使用v2，我还使用了已弃用的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。

使用v3，我尝试使用服务帐户进行身份验证，并使用相同的代码库

PHP Youtube API v3 - Direct Upload - Unauthorized message

我从API端点收到相同的错误消息：

调用POST https://www.googleapis.com/youtube/v3/videos?part=status%2Csnippet时出错：（401）未经授权

我还通过Google的tokeninfo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"
}

我发现的所有YouTube示例均基于OAuth2和用户授权。（就像这一个：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＆＃34;请授权上传YouTube视频的内容＆＃34;＆＃34; AND 视频应上传到我的YT频道而不是他们的频道。

如果没有可能使用API服务帐户，您能否提示我如何使用OAuth2做到这一点？： - ）

这是我目前的代码：

/** 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

            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");

无法使用服务帐户访问YouTube API

Issue 5370: Youtube v3 Google Service Account Access

您需要使用Oauth2您只需要进行一次身份验证。使用脱机访问保存刷新令牌。然后你可以用它来运行你的脚本。

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

YouTube API v3 - 直接上传到自己的频道
