在使用Meteor HTTP在Spotify API上请求access_token时,我无法解决问题.实际上,当我对Spotify https://accounts.spotify.com/api/token进行POST调用时.我收到以下回复:

{"statusCode":400,"content":"{\"error\":\"unsupported_grant_type\",\"error_description\":\"grant_type must be client_credentials, authorization_code or refresh_token\"}"

我认为这可能与Content-Type标头和BODY参数的编码有关,但我无法解决这个问题.我试图使用数据和参数,但没有一个工作.

这是我的代码:

HTTP.post("https://accounts.spotify.com/api/token", {
      data: {
        grant_type : "authorization_code",
        code : authCode,
        redirect_uri : Router.routes['redirect_spotify'].url()
      },
      headers: {
        'Authorization' : "Basic " + CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse("xxxx:yyyyy")),
        'Content-Type':'application/x-www-form-urlencoded'
      }
    }, function(error, result) {
      console.log("POST made with data : %j", result);
      if (error){
        Registrations.remove({userId : this.userId });
        return;
      }
      Registrations.update({
        userId : this.userId },
      {$set : {
        state: "Done",
        accessToken: result.access_token,
        //TODO expires
        refreshToken: result.refresh_token
        }},
      { upsert : true}
    );
    }); …
