Java中restTemplate携带Header请求

Map<String, String> requestBody = new HashMap<>();
requestBody.put("userId", userId);
requestBody.put("userName", userName);

HttpHeaders requestHeader = new HttpHeaders();
requestHeader.add("cookie", "cookie");
requestHeader.add("userInfo", "{userId:101,userName:userName}");

HttpEntity<Map<String, String>> httpEntity = new HttpEntity<>(requestHeader);
RestTemplate restTemplate = new RestTemplate();

ResponseEntity responseEntity = restTemplate.postForEntity(url, httpEntity, JSONObject.class);

JSONObject jsonObject = restTemplate.postForObject(url, httpEntity, JSONObject.class);

ResponseEntity<JSONObject> responseEntity = restTemplate.exchange(url, HttpMethod.GET, httpEntity, JSONObject.class, requestBody);
