curl POST to rest template

Question

curl -v POST -d '[23,24]' https://serverurl/api/list/GetByIds --header "Accept:application/json" --header "Content-Type:application/json" --header "Authorization: Bearer XYZ"

The above curl statement returns proper result. I am not sure how to send the same data using Spring RestTemplate.exchange . I don't need the whole code, I just want to know how I can send that list of integers [23,24].

You can use the exchange(RequestEntity<?> requestEntity, java.lang.Class<T> responseType) method. When you create parametrized RequestEntity you can add List<Integer> as the type of the Request entity. RequestEntity<List<Integer>> request = RequestEntity.post(new URI("http://example.com/bar")).accept(MediaType.APPLICATION_JSON).body(<actual list here>); — Rashin

Try following:

List<Integer> integers = new ArrayList<>(); integers.add(23); integers.add(24); restTemplate.exchange("url", HttpMethod.POST, new HttpEntity<>(integers), new ParameterizedTypeReference<List<Integer>>() { });

Replace List<Integer> in new ParameterizedTypeReference<List<Integer>>() with your response model.
