用RestTemplate 方法实现
private final RestTemplate restTemplate;
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.add("Content-Type", "application/json;charset=UTF-8");
HttpEntity<String> httpEntity = new HttpEntity<>(JSON.toJSONString(paramsMap), httpHeaders);
ResponseEntity<String> response = restTemplate.exchange(APIurl, POST, httpEntity, String.class);
if (response.getStatusCode() == HttpStatus.OK) {
JSONObject result = JSON.parseObject(response.getBody());
if (result.getInteger("code") == 200) {
}
}
