【问题描述】:
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 说您是从 liveBroadcast sn-p.liveChatId 获得的,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?
【问题讨论】:
-
我不明白为什么这不是链接问题的重复。链接的欺骗目标使用新的 API。
-
链接的问题是关于如何获取ID并使用它。我真的尝试以这种方式获取它,但我无法使用我的示例代码从结果中获取 liveChatId。 liveChatId 字段为空。这就是为什么我需要帮助! :D
-
您正在尝试从您自己的事件中获取
liveChatId对吗?不是其他用户的? -
是的,这正是我想要做的。我的活动已列出,但 $broadcastItem['sn-p']['liveChatId'] 始终为空!
-
好吧,这很奇怪。我现在可以获取 ID...但是只有当我使用 API(有效)创建广播时才会生成 liveChatId...而不是通过我的用户通过 www.youtube.com 生成?你为什么这么认为?
