php - 尝试使用 YouTube API 时出现需要登录错误

Question

我正在尝试设置一个可以通过 YouTube API 创建实时事件的脚本，并且我已经从 developer console 中删除了示例。并尝试将其修改为使用 API key ，因为它将转到我们自己的帐户，而不是用户将其用于自己的帐户。

另外，仅供引用，我正在使用 Google API PHP Client V1 .

我有以下代码:

require_once 'includes/Google/autoload.php';
require_once 'includes/Google/Client.php';
require_once 'includes/Google/Service/YouTube.php';

$client = new Google_Client();
$client->setApplicationName("My Title");
$client->setDeveloperKey("xxxxxxxxxxxxxx");

$client->setScopes('https://www.googleapis.com/auth/youtube');

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

try {
    // Create an object for the liveBroadcast resource's snippet. Specify values
    // for the snippet's title, scheduled start time, and scheduled end time.
    $broadcastSnippet = new Google_Service_YouTube_LiveBroadcastSnippet();
    $broadcastSnippet->setTitle('Test Broadcast');
    $broadcastSnippet->setScheduledStartTime('2017-01-30T00:00:00.000Z');
    $broadcastSnippet->setScheduledEndTime('2017-01-31T00:00:00.000Z');

    // Create an object for the liveBroadcast resource's status, and set the
    // broadcast's status to "private".
    $status = new Google_Service_YouTube_LiveBroadcastStatus();
    $status->setPrivacyStatus('unlisted');

    // Create the API request that inserts the liveBroadcast resource.
    $broadcastInsert = new Google_Service_YouTube_LiveBroadcast();
    $broadcastInsert->setSnippet($broadcastSnippet);
    $broadcastInsert->setStatus($status);
    $broadcastInsert->setKind('youtube#liveBroadcast');

    // Execute the request and return an object that contains information
    // about the new broadcast.
    $broadcastsResponse = $youtube->liveBroadcasts->insert('snippet,status', $broadcastInsert, array());

    // Create an object for the liveStream resource's snippet. Specify a value
    // for the snippet's title.
    $streamSnippet = new Google_Service_YouTube_LiveStreamSnippet();
    $streamSnippet->setTitle('Test Stream');

    // Create an object for content distribution network details for the live
    // stream and specify the stream's format and ingestion type.
    $cdn = new Google_Service_YouTube_CdnSettings();
    $cdn->setFormat("1080p");
    $cdn->setIngestionType('rtmp');

    // Create the API request that inserts the liveStream resource.
    $streamInsert = new Google_Service_YouTube_LiveStream();
    $streamInsert->setSnippet($streamSnippet);
    $streamInsert->setCdn($cdn);
    $streamInsert->setKind('youtube#liveStream');

    // Execute the request and return an object that contains information
    // about the new stream.
    $streamsResponse = $youtube->liveStreams->insert('snippet,cdn', $streamInsert, array());

    // Bind the broadcast to the live stream.
    $bindBroadcastResponse = $youtube->liveBroadcasts->bind(
        $broadcastsResponse['id'], 'id,contentDetails',
        array(
            'streamId' => $streamsResponse['id'],
        ));

    $htmlBody .= "<h3>Added Broadcast</h3><ul>";
    $htmlBody .= sprintf('<li>%s published at %s (%s)</li>',
                         $broadcastsResponse['snippet']['title'],
                         $broadcastsResponse['snippet']['publishedAt'],
                         $broadcastsResponse['id']);
    $htmlBody .= '</ul>';

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

    $htmlBody .= "<h3>Bound Broadcast</h3><ul>";
    $htmlBody .= sprintf('<li>Broadcast (%s) was bound to stream (%s).</li>',
                         $bindBroadcastResponse['id'],
                         $bindBroadcastResponse['contentDetails']['boundStreamId']);
    $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()));
}

?>

<!doctype html>
<html>
<head>
    <title>Bound Live Broadcast</title>
</head>
<body>
<?= $htmlBody ?>
</body>
</html>

但是当我运行它时，我得到了错误:

A service error occurred: Error calling POST https://www.googleapis.com/youtube/v3/liveBroadcasts?part=snippet%2Cstatus&key=xxxxxxxxxxxxxxxx: (401) Login Required

我在这里做错了什么？

此操作只能由通过 OAuth2 身份验证的用户执行，您不能仅使用您的开发人员 key 创建广播。在这种情况下，您想使用自己的帐户，因此您需要获取对该帐户有效的访问 token ，最好是“离线” token ，这样您就可以在过期后自动刷新它，这样您就可以只需手动通过同意屏幕一次。以下是有关 OAuth 2 流程的更多信息:

编辑:更准确地说，流程应该是这样的:

在单独的脚本中，你 完成获取离线访问 token 的过程 - 单击同意屏幕并代表您的帐户授予您的应用程序访问 API 的权限。

存储获得的 token 以供以后使用，例如将其保存在平面文件或数据库中。您只需要执行前两个步骤一次，稍后您的 token 可以自动刷新。

用户进入站点，您的脚本使用之前获得的 token 执行 API 操作。一切都发生在服务器端，无需用户输入。
