I have this method to make request:
@Override
public HttpEntity<MultiValueMap<String, String>> generateRequestEntity(Date date) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> map = new LinkedMultiValueMap<>();
map.add("key", "SOME_API_KEY");
map.add("source", "SOME_API_SOURCE");
if (date == null)
map.add("method", "getall");
else {
map.add("method", "getfrom");
map.add("date", new SimpleDateFormat("yyyy-MM-dd").format(date));
}
return new HttpEntity<>(map, headers);
}
I send a request and get a response, as recommended at following link: URL
HttpEntity<MultiValueMap<String, String>> request = generateRequestEntity(date);
ResponseEntity<OnlineSell[]> response = restTemplate.postForEntity(url, request, OnlineSell[].class);
OnlineSell[] onlineSells = response.getBody();
But I have a problem. I am failing when trying to parse JSON-response. OnlineSell - class, that must keep the answer BUT I just can’t create a structure that successfully stores the values of this answer. A very large and complex answer tree comes.
Answer: Can I get JSONObject from it to parse and save manually? Or can I get help with JSON parsing by previously updating this post and adding it (answer form Postman)?
What you can do is to consider the ResponseEntity as a String. Then afterwards you can use objectMapper with readValue(),
Something like this:
ResponseEntity<String> response = restTemplate().postForEntity(url, request, String.class);
String body = response.getBody();
OnlineSell[] onlineSells = new ObjectMapper().readValue(body, OnlineSell[].class);
