android InputStream 无法从服务器页面获取输入

Question

您好，我正在使用以下代码，但无法从 url 获取 iStream。 url returns 一个 JSON 数组。

URL url = new URL(tomato_search);
URLConnection urlConnection = url.openConnection();
InputStream iStream = new BufferedInputStream(urlConnection.getInputStream());
readStream(iStream);
iStream.close();

如果您使用 http 进行通信，最好使用 HttpURLConnection。

JsonArray jsonArray;
HttpURLConnection httpURLConnection = (HttpURLConnection) new URL("http://www.example.com/endpoint").openConnection();
httpURLConnection.setRequestMethod("GET");
httpURLConnection.setRequestProperty("Content-Type", "application/json;charset=utf-8");
httpURLConnection.connect();
InputStream is = httpsURLConnection.getInputStream();
try {
        BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
        StringBuilder sb = new StringBuilder();
        while (br.readLine() != null) {
            sb.append(br.readLine()).append("\n");
        }
        br.close();

        jsonArray = new JSONArray(sb.toString());
    } catch (IOException | JSONException e) {
        jsonArray = null;
    }
