我正在尝试通过HTTR和Spotify API在我的Spotify in R中创建一个播放列表。但是，我无法弄清楚如何构造POST请求。
这是我在R中使用的POST请求
HeaderValue = "Authorization Code"
n = "application/json"
response = POST(
'https://open.spotify.com/v1/users/(myuserid)/playlists',
accept_json(),
add_headers(Authorization = HeaderValue, "Content-Type" = n),
body = list(name = "New Playlist1", public = "true"),
encode = 'form',
verbose()
)
这是Spotify API网站上的请求应该是这样的：
POST /v1/users/121616946/playlists HTTP/1.1
Host: api.spotify.com
Content-Length: 40
Accept-Encoding: gzip, deflate, compress
Accept: application/json
User-Agent: Spotify API Console v0.1
Content-Type: application/json
Authorization: "Authorization Code"
{"name": "New Playlist", "public": true}enter code here
这是我在R控制台中获得的
POST /v1/users/121616946/playlists HTTP/1.1
Host: open.spotify.com
User-Agent: libcurl/7.43.0 r-curl/1.2 httr/1.2.1
Accept-Encoding: gzip, deflate
Accept: application/json
Authorization: "Authorization Code"
Content-Type: application/json
Content-Length: 32
name=New%20Playlist1&public=true
HTTP/1.1 404 Not Found
Server: nginx
Date: Fri, 25 Nov 2016 19:57:41 GMT
Content-Type: text/html; charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Keep-Alive: timeout=10
Vary: Accept-Encoding
Cache-Control: no-cache
Content-Encoding: gzip
Tl; Dr：我认为我的问题是POST的主体。我不认为我在通话中正确格式化了。我可能会遗漏别的东西，但我不确定是什么。授权令牌完全被授权执行我要求它做的事情，因此这不会是一个问题。
