基本认证json android

Question

我试图从网站上访问一些json数据。它具有基本身份验证，因此我无法访问数据并收到异常：Filenotfoundexception。我现在正走在正确的道路上，但我需要最后一步的帮助。我的代码是：

private class jsonConnection extends AsyncTask<Void, Void, Void> {

    @Override
    protected Void doInBackground(Void... voids) {

        String username = "---";
        String password = "---";
        String credentials = username + ":" + password;

        String sensorID = "sensors";
        String api = "api";
        String webURL = "https://" + credentials + "@---";

        String credBase64 = Base64.encodeToString(credentials.getBytes(), Base64.DEFAULT).replace("\n", "");

        try {

            URL url = new URL(webURL + "/" + sensorID + "/" + api);

            System.out.println(url);
            System.out.println(credentials);

            connection = (HttpsURLConnection) url.openConnection();


            connection.setUseCaches(false);

            connection.setReadTimeout(30000);
            connection.setConnectTimeout(30000);

            connection.setRequestMethod("GET");
            connection.setDoInput(true);

            connection.addRequestProperty("HTTP_Authorization", "basic" + credentials);

            connection.connect();

            InputStream stream = connection.getInputStream();

            bufferedReader = new BufferedReader(new InputStreamReader(stream));

            //StringBuffer buffer = new StringBuffer();

            String line = "";
            while (line != null) {
                line = bufferedReader.readLine();
                data = data + line;
            }

            //  JSONObject jsonObject = new JSONObject();
            //  jsonObject.put("coord", coord);

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

我知道这段代码足以建立与任何其他JSON数据的连接，但由于那里的基本身份验证似乎无法连接到这个网站的json。我事先感谢你的帮助！
