REST API call from spring boot not working

Question

I am trying to fetch live data from NSE options trading. Below code is not working and the request made is stuck without any response. Any workaround on this?

public void getLiveBankNiftyData() {
        String RESOURCE_PATH = "https://www.nseindia.com/api/option-chain-indices?symbol=BANKNIFTY";
        ResponseEntity<Object[]> responseEntity = restTemplate.getForEntity(RESOURCE_PATH, Object[].class);
        Object[] objects = responseEntity.getBody();
    }

Accessing the URL returns a 401. I think you must provide some security credentials — Simon Martinelli, Jul 25 '21 at 15:48
@SimonMartinelli : I am getting data when I directly hit below URL in browser.... https://www.nseindia.com/api/option-chain-indices?symbol=BANKNIFTY — Devs, Jul 25 '21 at 15:50
Try to use an URI for the call like `URI uri = new URI(RESOURCE_PATH);` and then call `restTemplate.getForEntity(uri ...` — Janos Vinceller, Jul 25 '21 at 15:59
You could also use some extra logging for your restTemplate like described here: https://stackoverflow.com/questions/7952154/spring-resttemplate-how-to-enable-full-debugging-logging-of-requests-responses — Janos Vinceller, Jul 25 '21 at 16:00
Anyway, I get: `Resource not found` if browsing your URL you've provided in your code. — Janos Vinceller, Jul 25 '21 at 16:02
@JanosVinceller : For me that URL is working fine in browser and in postman getting 401 and sometimes 200 as well. I will try extra logging. — Devs, Jul 25 '21 at 16:05

i tried this

    // request url
    String url = "https://www.nseindia.com/api/option-chain-indices?symbol=BANKNIFTY";

    // create an instance of RestTemplate
    RestTemplate restTemplate = new RestTemplate();

    // make an HTTP GET request
    String json = restTemplate.getForObject(url, String.class);

    // print json
    System.out.println(json);

ranavirkar : Did that work for you? This didn't work for me. I still see the same issue. – Devs Jul 25 '21 at 18:16
Yes if we directly hit that URl then we get values in postman, But the concern is different here. My code is not able to load the values. Anyways thank you all. I found a way out. Instead of using RestTemplate I used WebClient and this solved the issue. – Devs Jul 29 '21 at 03:40
