post请求方式 - 抖音生活服务 使用restTemplate而不使用httpClient

public static String doPostForJson(String url, String json,String byteAuthorization) {
        RestTemplate restTemplate = new RestTemplate();

        logger.info("restTemplate invoke post method. url:[{}], json:[{}]", url, json);
        long startTime = System.currentTimeMillis();
        String result = "";

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.add("Byte-Authorization",byteAuthorization);

        HttpEntity<String> request = new HttpEntity<>(json, headers);
        result = restTemplate.postForEntity(url,request,String.class).getBody();


        logger.info("restTemplate invoke [{}] consume time is,[{}] ms.", url, System.currentTimeMillis() - startTime);
        logger.info("restTemplate invoke post method. result:[{}]", result);
        return result;
    }
