使用 Meteor HTTP 在 Spotify API 上请求 access_token 时不支持的授权类型错误 [英] Unsupported grant type error when requesting access_token on Spotify API with Meteor HTTP

问题描述

在使用 Meteor HTTP 在 Spotify API 上请求 access_token 时，我一直无法解决问题.事实上，当我对 Spotify 进行 POST 调用时 https://accounts.spotify.com/api/token.我得到以下回复:

I've been unable to solve a problem while requesting an access_token on Spotify API with Meteor HTTP. Indeed, when I make a POST call to the Spotify https://accounts.spotify.com/api/token. I get the following response :

{"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，但我一直无法解决此问题.我尝试同时使用 data 和 params，但这些都不起作用.

I think this may have something to do with the Content-Type header and the encoding of the BODY parameter but I haven't been able to solve this issue. I tried to use both data and params and none of these worked.

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}
    );
    });

Thank you all in advance :) Love Meteor

推荐答案

您需要使用 params 而不是 data.因此，您的代码将是:

You need to use params instead of data. Thus, your code would be:

HTTP.post("https://accounts.spotify.com/api/token", {
  params: {
    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) {
   ...
});
