Your code is fine You can also use the same thing in this way   public static String getResponseFromJsonURL String url        String jsonResponse   null      if  CommonUtility isNotEmpty url             try                               For getting response from HTTP URL start                              URL object   new URL url                HttpURLConnection connection    HttpURLConnection  object                      openConnection                   int timeOut   connection getReadTimeout                connection setReadTimeout 60   1000               connection setConnectTimeout 60   1000               String authorization  xyz xyz 123               String encodedAuth  Basic   Base64 encode authorization getBytes                 connection setRequestProperty  Authorization   encodedAuth               int responseCode   connection getResponseCode                  String responseMsg   connection getResponseMessage                 if  responseCode    200                    InputStream inputStr   connection getInputStream                    String encoding   connection getContentEncoding      null    UTF-8                            connection getContentEncoding                    jsonResponse   IOUtils toString inputStr  encoding                                   For getting response from HTTP URL end                                           catch  Exception e                e printStackTrace                         return jsonResponse      Its Return response code 200 if authorizationis success

I have used the following code in the past and it had worked with basic authentication enabled in TomCat   URL myURL   new URL serviceURL   HttpURLConnection myURLConnection    HttpURLConnection myURL openConnection     String userCredentials    username password   String basicAuth    Basic     new String Base64 getEncoder   encode userCredentials getBytes       myURLConnection setRequestProperty   Authorization   basicAuth   myURLConnection setRequestMethod  POST    myURLConnection setRequestProperty  Content-Type    application x-www-form-urlencoded    myURLConnection setRequestProperty  Content-Length        postData getBytes   length   myURLConnection setRequestProperty  Content-Language    en-US    myURLConnection setUseCaches false   myURLConnection setDoInput true   myURLConnection setDoOutput true     You can try the above code   The code above is for POST  and you can modify it for GET

With RestAssurd you can also do the following    String path   baseApiUrl    This is the base url of the API tested     URL url   new URL path       given      Rest Assured syntax              contentType  application json      API content type             given   header  headerName    headerValue      Some API contains headers to run with the API              when                get url               then                statusCode 200     Assert that the response is 200 - OK

Just cause I don t see this bit of information in the answers above  the reason the code snippet originally posted doesn t work correctly is because the encodedBytes variable is a byte   and not a String value  If you pass the byte   to a new String   as below  the code snippet works perfectly   encodedBytes   Base64 encode authorization getBytes    0   authorization    Basic     new String encodedBytes
