org.springframework.web.client.HttpClientErrorException: 400 Bad Request

J'utilise Spring Boot. J'ai un api de repos [~ # ~] après [~ # ~] appel que j'ai besoin d'envoyer le corps en utilisant x-www-form-urlencoded , aucun en-tête n'est requis pour l'appel. Je peux frapper cette URL depuis le facteur et une ligne est créée avec succès dans db. Mais lorsque j'essaie d'appeler cela depuis Java, je reçois une exception de 400 requêtes incorrectes.

Voici ce que j'ai essayé en Java.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
        map.add("param1", "123");
        map.add("param2", "456");
        map.add("param3", "789");
        map.add("param4", "123");
        map.add("param5", "456");

    HttpHeaders headers = new HttpHeaders();
    final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map,
                headers);

        try {
            RestTemplate restTemplate = new RestTemplate();
            String response = restTemplate.postForObject(
                    "https://url", entity,
                    String.class);

            System.out.println(response);
        } catch (final Exception e) {
            throw new RuntimeException();
        }

Je reçois cette exception.

org.springframework.web.client.HttpClientErrorException: 400 Bad Request

J'ai également essayé comme ci-dessous et j'ai obtenu la même exception.

ResponseEntity<String> x = restTemplate.exchange("https://url", HttpMethod.POST,
                    map, String.class);

Voici le stacktrace complet

C'est ce qui a fonctionné pour moi. Le problème est antérieur. Je n'ai pas défini le type de contenu (en-tête) lorsque j'ai utilisé la méthode d'échange.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    }

ExternalCallBadRequestException et ExternalCallServerErrorException sont les exceptions personnalisées ici.

Remarque: N'oubliez pas que HttpClientErrorException est levée lorsqu'une erreur 4xx est reçue. Donc, si la demande que vous envoyez est incorrecte, soit en définissant l'en-tête ou en envoyant des données incorrectes, vous pourriez recevoir cette exception.
