我用postman调用了这个函数，可以很好地工作，但是使用restemplate会产生400个错误。myurl未编码，其纯字符串=https://blabla.com/rest/create
getreqbody（）返回一个有效的jsonnode
这里怎么了？任何建议都将不胜感激！

restTemplate1 = new RestTemplate();
ResponseEntity<JsonNode> response1 =null;
Object resObj1 =null;
try {
     RequestEntity<JsonNode> request = RequestEntity
            .post(URI.create(myURl))
            .header("Authorization", "Basic " + basicAuth)
            .contentType(MediaType.APPLICATION_JSON)
            .body(getReqBody());
     System.out.println(" My actual Request to -->" + request.toString());
     response1 = restTemplate1.exchange(request, JsonNode.class);
     }catch(Exception e) {
        System.out.println("Caught it in Exception "+ e);
        logger.error(" Error from Creation ==>" +e);
     }
