我试图使用restemplate将数据发布到我的api，但发布时它返回400个错误请求异常。我怎么能修好它？

public void postDataToApi(List<String> accountIds, String myApiUrl) {
  ObjectMapper mapper = new ObjectMapper();
  HttpHeaders headers = new HttpHeaders();
  headers.setContentType(MediaType.APPLICATION_JSON);
  String accountIdsJsonList = mapper.writeValueAsString(accountIds);
  HttpEntity<String> entity = new HttpEntity<String>(accountIdsJsonList, headers);
  RestTemplate restTemplate = new RestTemplate();
  String result = restTemplate.postForObject(myApiUrl, entity, String.class);
}

我想发布数据的api是yahooapi
