如何使用用户名和密码登录Spotify？

Question

由于问题所在，我想使用用户名和密码登录Spotify。 我不想使用应用程序或嵌入式网络视图登录，使我的应用程序更清洁。我正在使用我自己的GUI来尝试登录。

有没有办法做到这一点？我不太熟悉API调用，但我找不到方法。

我想到了Spotify API。这是主流程：

Session session = new Session(); 

    try { 
     String response = ""; 
     URL url = new URL(GET_TOKEN_URL); 
     HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); 
     httpURLConnection.setRequestMethod(POST); 

     String credentials = params[0]+":"+params[1]; 
     Log.d(getClass().getName(), credentials); 
     String basicAuth ="Basic "+new String(android.util.Base64.encode(credentials.getBytes(), Base64.DEFAULT)); 
     Log.d(getClass().getSimpleName(), basicAuth); 
     httpURLConnection.setRequestProperty(AUTH,basicAuth); 
     Uri.Builder builder = new Uri.Builder() 
       .appendQueryParameter(GRANT_TYPE, CLIENT_CREDENTIALS); 

     String query = builder.build().getEncodedQuery(); 

     OutputStream os = httpURLConnection.getOutputStream(); 
     BufferedWriter writer = new BufferedWriter(
       new OutputStreamWriter(os, "UTF-8")); 
     writer.write(query); 
     writer.flush(); 
     writer.close(); 
     os.close(); 

     httpURLConnection.connect(); 

     int responseCode=httpURLConnection.getResponseCode(); 

     session.setResponseCode(responseCode); 

     if (responseCode == HttpsURLConnection.HTTP_OK) { 
      String line; 
      BufferedReader br=new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream())); 
      while ((line=br.readLine()) != null) { 
       response+=line; 
      } 
     }else;{ 
      Log.e(getClass().getSimpleName(), "ERROR:" + responseCode); 
      response = "Something went wrong"; 
     } 
     Log.d(getClass().getSimpleName(), response); 

    } catch (MalformedURLException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally{ 

    } 
    return session; 

请注意，会话只是一个持有响应代码的类。
