400错误请求错误。

有没有人有任何想法？

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

HttpHeaders headers = new HttpHeaders();
headers.add("X-Shopify-Access-Token", "9a4d5c56a7edf1ac5bb17aa1c");
headers.add("Content-Type", MediaType.APPLICATION_JSON.toString());
headers.add("Accept", MediaType.APPLICATION_JSON.toString());

HttpEntity formEntity = new HttpEntity(headers);
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
ResponseEntity<String> responseEntity = restTemplate.exchange("https://mysite.myshopify.com/admin/orders/406287121/fulfillments.json",HttpMethod.POST,  formEntity,String.class);
System.out.println("Response="+responseEntity.getBody());
