该方法接收一个JSON字符串参数phoneNum  内容：   {"phone":"13712312312"}
然后解析参数中的手机号，作为data去调用URL接口，接收接口返回的复合JSON并解析，拿到想要的数据



public String queryUserResumeURLInfo(String phoneNum) {

        System.out.println("this is phoneNum: ======"+phoneNum);

        if(phoneNum.length() == 0){
            log.info("手机号为空！" );
            return null;
        }
        // 请求地址
        String url = "访问认证的URL";
        HttpHeaders headers = new HttpHeaders();
        String mediaType = MediaType.APPLICATION_JSON_VALUE;
        headers.setContentType(MediaType.parseMediaType(mediaType));
        headers.set("Accept", mediaType);
//        headers.set("Basic Auth", "uVJowCwUE08z2Hfw0aLXTZvZo66C19Rk");

        headers.set("Authorization", "Basic " + Base64.getUrlEncoder().encodeToString(("用户名" + ":" + "密码").getBytes()));



        Map<String, Object> map = new HashMap<>();

//传递参数，这里解析了传进来的JSON类型的手机号，并作为参数传给调用的接口
        map.put("phone", phoneNum.substring(phoneNum.indexOf(":")+2,phoneNum.lastIndexOf("}")-1));
        JSONObject json = new JSONObject(map);

//        System.out.println("this is json: ======"+json.toString());

        HttpMethod method = HttpMethod.POST;
        try {
            ResponseEntity<JSONObject> result = RestUtil.request(url, method, headers, null, json, JSONObject.class);
            if (result != null && result.getBody() != null) {
                log.info("返回结果：{}" ,result.getBody().toJSONString());

                JSONObject jsonObject = JSONObject.parseObject(result.getBody().toString());

               String resumeDataInfo =jsonObject.getJSONArray("data").getJSONObject(0).getJSONObject("basicInfo").getString("ehrCandidateExternalLink");
//               System.out.println("this is data:-------"+resumeDataInfo);

                return resumeDataInfo;

            } else {
                log.warn("查询失败,url={}",url);
            }
        }catch (Exception e){
            log.error("查询发生异常,url={}",url,e);
        }


        return null;
    }
