Spotify API 返回 {"error":"unsupported_grant_type","error_description":"grant_type 参数丢失"}发布刷新令牌请求 (Ruby)

Question

我正在调用 Spotify api 来获取刷新令牌，但始终得到方法 {"error":"unsupported_grant_type","error_description":"grant_type 参数丢失"} 即使我的代码显示为

grant_type: 'refresh_token'

并且在阅读文档后不确定该问题，任何帮助将不胜感激！

这是我到目前为止的代码

@response = HTTParty.post("https://accounts.spotify.com/api/token",
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
      },
      body: {
        grant_type: 'refresh_token',
        refresh_token: ENV['REFRESH_TOKEN'],
        client_id: ENV['CLIENT_ID']
      }.to_json)

Answer 1

哎呀，我相信这就是解决方案 - 我未经授权就发送了它

    @response = HTTParty.post("https://accounts.spotify.com/api/token", headers: { 'Content-Type' => 'application/x-www-form-urlencoded', 'Authorization' => "Basic #{Base64.strict_encode64("#{ENV['CLIENT_ID']}:#{ENV['CLIENT_SECRET']}")}" }, body: { grant_type: 'refresh_token', refresh_token: ENV['REFRESH_TOKEN'], } ) end
