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;}
