由于这是关于刚刚发布的新 YouTube API 的问题，因此不是重复的。

我正在尝试从 YouTube API 3 获取聊天消息。我已尽我所能，但我被卡住了。

我需要 liveChatId 才能获取它们，但我不知道如何检索该值。API 说您从 liveBroadcast snippet.liveChatId 获得它，但是使用我在这篇文章中附加的代码，liveChatId 字段中没有任何值。它只是空的。如何正确检索 liveChatId？

<?php
session_start();

// Call set_include_path() as needed to point to your client library.
require_once 'Google/autoload.php';
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';

$OAUTH2_CLIENT_ID = 'MY-CLIENT-ID';
$OAUTH2_CLIENT_SECRET = 'MY-CLIENT-SECRET';

$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$client->setScopes('https://www.googleapis.com/auth/youtube');
$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],
    FILTER_SANITIZE_URL);

$client->setRedirectUri($redirect);


// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);
$_SESSION['state'] = $_GET['state'];
if (isset($_GET['code'])) {
  if (strval($_SESSION['state']) !== strval($_GET['state'])) {
    die('The session state did not match.');
  }

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

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

// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
  try {
    // Execute an API request that lists broadcasts owned by the user who
    // authorized the request.
    $broadcastsResponse = $youtube->liveBroadcasts->listLiveBroadcasts(
        'id,snippet',
        array(
            'mine' => 'true',
        ));

var_dump($broadcastsResponse['items']);

    $htmlBody .= "<h3>Live Broadcasts</h3><ul>";
    foreach ($broadcastsResponse['items'] as $broadcastItem) {
      $htmlBody .= $broadcastItem['snippet']['title'] ."<br />Chat ID: ". $broadcastItem['liveChatId'] ."<br />ID: ". $broadcastItem['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>My Live Streams</title>
</head>
<body>
  <?=$htmlBody?>
</body>
</html>

我在哪里迷路了？

你的评论暴露了问题。YouTube 目前不支持将实时通话与“立即直播”混合并通过 API 创建事件。使用一种流或另一种流完成现场活动，而不是互换两者。
