如何获取Twitch视频缩略图URL？

Question

Youtube等视频分享网站有一个视频缩略图终点 示例：http://img.youtube.com/vi/youtube_id/default.jpg
其中youtube_id =视频的ID

所以我可以做到 <img src="http://img.youtube.com/vi/youtube_id/default.jpg"> 没有问题

抽搐也有类似的东西吗？

Answer 1

更新2018年

Twitch要求您使用其API，以便可以访问视频缩略图。
显然是因为缩略图的网址可能会更改

这是有关访问抽搐视频缩略图的简单指南

1. 您必须有权访问Twitch开发API-为此，您需要在https://glass.twitch.tv

注册一个帐户

2. 注册帐户后，您必须从twitch开发人员仪表板中创建一个应用程序

3. 创建应用程序后，将为您提供要用于该应用程序的客户端ID-请注意，该应用程序将是使用twitch API（例如您的网站）的应用程序

1. 您现在可以将client_id作为查询字符串参数传递给https://api.twitch.tv/kraken/videos/106400740?client_id=xxxxxxx，其中106400740是视频ID（请注意，此处的“ kraken”是常量-不确定其名称后面的来源）-请注意，如果您不包含client_id
，请求将返回一个包含错误消息的JSON对象。

请求将返回一个类似于以下内容的JSON对象：

在缩略图数组下，您可以找到视频的url。

PS：如您所见，缩略图数组的长度为4-在这一点上，我认为这是因为视频作者可以放置的图像大小不同
