我使用oauth post請求時獲取HTTP 400

我正在嘗試爲我爲android編寫的應用程序使用oauth。我到目前爲止，正確的授權碼被返回到我的應用程序。現在需要發出一個請求來獲取訪問/刷新令牌。要做到這一點我有下面的代碼：我使用oauth post請求時獲取HTTP 400

class post_get_access_token extends AsyncTask<String, Void, String> { 

private Exception exception; 

protected String doInBackground(String... code) { 
    try { 
     String url = "https://login.eveonline.com/oauth/token"; 
     String charset = "UTF-8"; 

     String grant_type = "authorization_code"; 
     String enc_auth = Base64.encodeToString("9d7dcbb0380f450ea0d2b435b60f4c15:ssEAFgv5PfEs29bluxs9N3milKgC7j6saILCtMPw".getBytes(), Base64.DEFAULT); 


     String query = null; 
     try { 
      query = String.format("grant_type=%s&code=%s", 
        URLEncoder.encode(grant_type, charset), 
        URLEncoder.encode(code[0], charset)); 
     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     } 
     Log.i("eve_token_query",query); 

     URLConnection connection = null; 
     try { 
      connection = new URL(url).openConnection(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     connection.setDoOutput(true); // Triggers POST. 
     //connection.setRequestProperty("Accept-Charset", charset); 
     connection.setRequestProperty("Authorization", enc_auth); 
     connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=" + charset); 

     try (OutputStream output = connection.getOutputStream()) { 
      output.write(query.getBytes()); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     for (Map.Entry<String, List<String>> header : connection.getHeaderFields().entrySet()) { 
      Log.i("eve_response_header",header.getKey() + "=" + header.getValue()); 
     } 
     //InputStream response = connection.getInputStream(); 

    } catch (Exception e) { 
     this.exception = e; 

     return null; 
    } 

    return "bla"; 
} 

protected void onPostExecute(String... response) { 
    // TODO: stuff 
} 


}

但答案標題是這樣的：

10-23 18:54:43.613 29926-30158/com.jbs.evecompanion I/eve_response_header: null=[HTTP/1.1 400 Bad Request]

正如你可以看到給了我一個「錯誤的請求」。

事實證明，Base64編碼做了一些奇怪的事情。相反Base64.DEFAULT的
我不得不使用Base64.NO_WRAP

太行會

String enc_auth = Base64.encodeToString("9d7dcbb0380f450ea0d2b435b60f4c15:ssEAFgv5PfEs29bluxs9N3milKgC7j6saILCtMPw".getBytes(), Base64.NO_WRAP);

否則它將編碼字符串中添加隨機換行符。
