如何将 YouTube 句柄映射到频道 ID

Question

Youtube 最近推出了 handles 功能，他们为用户提供 youtube.com/@xxx 输入用户名，当访问这些 URL 时会显示用户的频道，但我在 API 存储库中找不到任何文档或参考。

如何从 YouTube 用户的句柄中提取 YouTube 用户频道 ID？

Answer 1

再一次YouTube Data API v3 不提供基本功能。

我建议您尝试我的开源YouTube操作API。事实上，通过获取 https://yt.lemnoslife.com/channels?handle=@HANDLE，您将获得您在

item["id"]

中查找的 YouTube 频道 ID。

例如使用 YouTube 频道句柄

@WHO

，您将得到：

{
    "kind": "youtube#channelListResponse",
    "etag": "NotImplemented",
    "items": [
        {
            "kind": "youtube#channel",
            "etag": "NotImplemented",
            "id": "UC07-dOwgza1IguKA86jqxNA"
        }
    ]
}

浪费了大约 2 个小时来导出以下工作代码/修复...

Answer 3

截至2023年12月，YouTube API仍然没有支持通过句柄拉取频道数据的端点。

使用 PHP，我确实找到了一些解决方法。

use Symfony\Component\BrowserKit\HttpBrowser;
use Symfony\Component\HttpClient\HttpClient;

public function getChannelIDFromUrl($url) {
 $httpClient = new HttpBrowser(HttpClient::create());
            $crawler = $httpClient->request('GET', $url);
            $channelUrl = $crawler->filterXPath('//meta[@property=\'og:url\']')
                ->attr('content');
            return explode('/', $channelUrl)[4];
}

注意：$url 返回一个带有@句柄的字符串。
