如何通过 YouTube 数据 API V3 端点搜索通过频道 ID 获取频道图标

Question

我在 /search enpoint 上发出请求：https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UC8M5YVWQan_3Elm-URehz9w&key=AIzaSyAp8yGkCqT9e9p7IzgpE24KGoqLRgNhOg0&q=Utopia

我收到了视频及其预览，但频道图标没有出现，我阅读了如何获取频道图标，我明白了，https://developers.google.com/youtube/v3/docs/search/list你需要什么才能从 Id 中获取 channelId class 并将其传递给 channelId 查询参数，之后有关频道的数据将进入 Snippet 模型，图标将进入缩略图，但我不明白如何以及从何处从模型 ID 获取 channelId 以及在哪里它被传递给请求参数，最好从哪里得到它？

Answer 1

频道图标，你是指频道头像？ - 如果是，那么，是的，频道图标 出现在响应的 youtube#channel 中。

这是您使用 your sample request 收到的部分回复：

您可以从此回复中获得频道图标，如下所示：

JSON_response.items[0].snippet.thumbnails.medium.url

您将获得：

其中 JSON_response 是请求的响应。我不确定您是如何阅读回复中的项目的，但是，我希望这个回答对您有所帮助。
