        basicDownloadForm.setDataType("INTERCEPT");
        basicDownloadForm.setPdaCode("JSYG22200110001");
        basicDownloadForm.setVersionNo("1573285609000");

        String content = JSON.toJSONString(basicDownloadForm);

        HttpEntity<String> httpEntity = new HttpEntity<>(content, httpHeaders);

        String response = restTemplate.postForObject("http://xxxxxx.xxx.xx/xxxxxxx/xxxxx/xxxxxxxxxxxx", httpEntity, String.class);
        System.out.println(response);

        MultiValueMap<String, String> multiValueMap = new LinkedMultiValueMap<>();
        multiValueMap.add("orgCode","900000");
        multiValueMap.add("dataType","INTERCEPT");
        multiValueMap.add("pdaCode","JSYG22200110001");
        multiValueMap.add("versionNo","1573285609000");

        HttpEntity<MultiValueMap<String, String>> httpEntity = new HttpEntity<>(multiValueMap, httpHeaders);
