IT技术 - 访问控制允许来源被拒绝 Spotify api - 吾爱随笔录

我正在尝试像这样访问 Spotify API 令牌：

$.ajax({
  url: "https://accounts.spotify.com/api/token",
  type: 'POST',
  contentType: "application/json; charset=\"utf-8\"",
  crossDomain: true,
  data: {
    grant_type: "authorization_code",
    code: code,
    redirect_uri: "http://www.bancadigital.com.br/spotifyteste/callback.html"
  },
  processData: false,
  dataType: "json",
  headers: {
    Authorization: "Basic " + utf8_to_b64(key)
  },
  success: function( response ) {
    alert(response.access_token);
  },
});

但服务返回以下错误：

XMLHttpRequest 无法加载https://accounts.spotify.com/api/token。请求的资源上不存在“Access-Control-Allow-Origin”标头。Origin ' http://www.bancadigital.com.br ' 因此不允许访问。

有谁知道我如何访问该服务？
