Following is the code that I'm trying to use. But when I run the request url in web browser I'm getting response without issue.But by using java code I'm unable to extract data. Please help

String uri = "http://192.168.77.6/Ivr_ABN_API/?id?id="
            + mobile;
    URL url;
    Gson json = null;
    try {
        url = new URL(uri);
        json = new Gson();

        HttpURLConnection connection;
        access_token = db.getAccessTokenFromDB();
        connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");

        System.out.println("URL:" + uri);

        connection.setRequestProperty("Content-Type", "application/json");
        int status = connection.getResponseCode();
        resCode = Integer.toString(status);


                InputStream in = connection.getInputStream();
                BufferedReader bf = new BufferedReader(
                        new InputStreamReader(in));
                System.out.println("bf.readLine() - "+bf.readLine());

                while ((output = bf.readLine()) != null) {
                    JSONObject obj = new JSONObject(output);
                    System.out.println("output is "+output);
                    resCode = obj.getString("resCode");
                    resDesc = obj.getString("COUNT");

                }


        connection.disconnect();

推荐答案

尝试一下

BufferedReader in = new BufferedReader(new InputStreamReader(in, StandardCharsets.UTF_8));

代替

 BufferedReader bf = new BufferedReader(new InputStreamReader(in));

因为您需要添加一种编码技术，通过该技术，BufferedReader能够以正确的格式编码任何特殊字符.

because you need to add encoding technique by which a BufferedReader able to encode any special character in proper format.

希望这对您有所帮助.

谢谢.
