        Compare CAPTCHA audio input value

        This section describes API examples that compare the value of the CAPTCHA audio file entered by the user to the actual CAPTCHA value (string or number).

        Java

        The following is a Java-based sample code for the Compare CAPTCHA audio input value API.

        import java.io.BufferedReader;
        import java.io.InputStreamReader;
        import java.net.HttpURLConnection;
        import java.net.URL;
        
        public class APIExamCaptchaSkeyResult {
        
            public static void main(String[] args) {
                String clientId = "YOUR_CLIENT_ID";//Application's client ID value";
                String clientSecret = "YOUR_CLIENT_SECRET";//Application's client secret value";
                try {
                    String code = "0"; // Set to 0 for key issuance and 1 for CAPTCHA audio comparison
                    String key = "CAPTCHA_KEY"; // Key value received when issuing a CAPTCHA key
                    String value = "USER_VALUE"; // CAPTCHA value entered by the user
                    String apiURL = "https://naveropenapi.apigw.ntruss.com/scaptcha/v1/skey?code=" + code +"&key="+ key + "&value="+ value;
        
                    URL url = new URL(apiURL);
                    HttpURLConnection con = (HttpURLConnection)url.openConnection();
                    con.setRequestMethod("GET");
                    con.setRequestProperty("X-NCP-APIGW-API-KEY-ID", clientId);
                    con.setRequestProperty("X-NCP-APIGW-API-KEY", clientSecret);
                    int responseCode = con.getResponseCode();
                    BufferedReader br;
                    if(responseCode==200) { // Successful call
                        br = new BufferedReader(new InputStreamReader(con.getInputStream()));
                    } else {  // Error occurred
                        br = new BufferedReader(new InputStreamReader(con.getErrorStream()));
                    }
                    String inputLine;
                    StringBuffer response = new StringBuffer();
                    while ((inputLine = br.readLine()) != null) {
                        response.append(inputLine);
                    }
                    br.close();
                    System.out.println(response.toString());
                } catch (Exception e) {
                    System.out.println(e);
