如果您询问如何从您在问题中创建的响应对象中获取艺术家姓名,您可以这样做:
> Artist$name
“弗兰克·西纳特拉”
如果您询问如何通过艺术家姓名查询 API,相关endpoint https://developer.spotify.com/web-api/artist-endpoints/是按姓名搜索艺术家,这将允许您找到 ID(因为 API 是基于 ID 而不是搜索功能,所以您需要它):
/v1/search?type=artist
The endpoint https://developer.spotify.com/web-api/artist-endpoints/获得几位艺术家的方法是:
/v1/artists?ids={ids}
他们实际上提供了一个很好的 jsFiddle 示例,根据名称进行(单个)艺术家搜索:
http://jsfiddle.net/JMPerez/0u0v7e1b/ http://jsfiddle.net/JMPerez/0u0v7e1b/
此搜索文档页面显示了他们如何构建搜索 URI:
https://developer.spotify.com/web-api/search-item/ https://developer.spotify.com/web-api/search-item/
把它们放在一起
这是一个在 R 中根据艺术家姓名进行搜索的完整示例。假设我们要搜索 YTCracker,即书呆子说唱之王:
artistName = 'ytcracker'
HeaderValue = paste0('Bearer ', mytoken)
URI = paste0('https://api.spotify.com/v1/search?query=', artistName,'&offset=0&limit=20&type=artist')
response2 = GET(url = URI, add_headers(Authorization = HeaderValue))
Artist = content(response2)
Artist
The Artist
对象具有 ID、URI、流派、关注者数量以及其他足以探索该艺术家、他们的专辑和相关艺术家等的 Spotify API 其余部分的信息:

请注意,我对搜索结果的大小设置了可选限制。另请注意,如果愿意,您可以使用相同的搜索结果来查询专辑封面图像等内容,如 jsFiddle 示例中所示。
多位艺术家
好的,现在我根据我的搜索获得了 YTCracker 的 ID,并从您的问题中获得了 Sinatra 的 ID,并且我想同时查询两位艺术家的 API。我可以这样做。只要您有 ID,您也可以为 2 位以上的艺术家执行此操作。
