我已经在Spotify的开发者应用程序部分创建了一个客户端ID和密钥。我引用这个文档,并希望通过选择多个艺术家来扩展它。
https://www.r bloggers.com/the -欧洲- 2016首歌大赛——————r -闪亮app/
在这个例子中,他们只选择了1个艺术家ID但是这里有一些漏洞,
1)如何获得艺术家名称而不是艺术家ID,因为我在任何地方都找不到艺术家ID的术语表键?
2)你如何选择多个艺术家而不是一个。
例如,我如何选择Frank Sinatra和Elvis Presley?
代码如下:
library(httr)
clientID = '#############################'
secret = '########################'
response = POST(
'https://accounts.spotify.com/api/token',
accept_json(),
authenticate(clientID, secret),
body = list(grant_type = 'client_credentials'),
encode = 'form',
verbose()
)
mytoken = content(response)$access_token
## Frank Sinatra spotify artist ID
artistID = '1Mxqyy3pSjf8kZZL4QVxS0'
HeaderValue = paste0('Bearer ', mytoken)
URI = paste0('https://api.spotify.com/v1/artists/', artistID)
response2 = GET(url = URI, add_headers(Authorization = HeaderValue))
Artist = content(response2)
Artist
我的目标是获得每个艺术家歌曲的所有属性,例如可跳舞性等。
任何帮助将是伟大的,谢谢!
如果你问如何从你在问题中创建的响应对象中获取艺术家的名字,你可以这样做:
> Artist$name
"弗兰克·辛纳屈"
如果你问如何通过艺术家名字查询API,相关的端点是艺术家名字搜索,这将允许你找到ID(因为API是基于ID而不是搜索功能,所以你需要):
/v1/search?type=artist
获取多个艺术家的端点是:
/v1/artists?ids={ids}
他们实际上提供了一个很好的jsFiddle示例,基于名称(单个)艺术家搜索:
http://jsfiddle.net/JMPerez/0u0v7e1b/这个搜索文档页面展示了他们如何构建搜索URI:
https://developer.spotify.com/web-api/search-item/把它们放在一起
下面是一个完整的基于r中艺术家名字的搜索示例,假设我们要搜索YTCracker, nerd rap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
Artist
对象具有ID, URI,类型,关注者数量和其他足够的信息来探索该艺术家,他们的专辑和相关艺术家等Spotify API的其余部分:

注意,我对搜索结果的大小设置了一个可选的限制。还请注意,如果愿意的话,您可以使用相同的搜索结果来查询诸如专辑封面图像之类的内容,就像jsFiddle示例中那样。
多个Arists好的,现在我有了根据我的搜索得到的YTCracker的ID和从你的问题得到的Sinatra的ID,我想同时查询这两位艺术家的API。我可以这样做。只要你有ID,你可以为2个以上的艺术家,以及。

我构建了spotifyr
包来做到这一点!
install.packages('spotifyr')
library(spotifyr)
library(tidyverse)
Sys.setenv(SPOTIFY_CLIENT_ID = '[YOUR_SPOTIFY_CLIENT_ID]')
Sys.setenv(SPOTIFY_CLIENT_SECRET = '[YOUR_SPOTIFY_CLIENT_SECRET]')
artist_names <- c('Frank Sinatra', 'Elvis Presley')
artist_audio_features <- map_df(artist_names, function(artist) {
get_artist_audio_features(artist) %>%
mutate(artist_name = artist)
})
