使用阿里云的身份证实名认证接口

如何使用身份证实名认证接口呢？充钱！充钱！充钱！

1. 首先，去阿里云市场购买身份证实名认证服务。
   
   

2. 购物之后，我们会得到：AppKey，AppSecret，AppCode

3. 根据官方提供的实例代码，使用实名认证接口。我这里有一个自己测试过的代码，发生请求，用到的Spring提供的RestTemplate类。

       /**
        *
        * @param realName 用户的真实姓名
        * @param carNum 用户的身份证号码
        * @return 验证的结果
        */
       public static boolean check(String realName, String carNum) {
           MultiValueMap<String, Object> paramMap = new LinkedMultiValueMap<>();
           paramMap.put("cardNo", Collections.singletonList(carNum));
           paramMap.put("realName", Collections.singletonList(realName));
   
           HttpHeaders headers = new HttpHeaders();
           headers.put("Authorization", Collections.singletonList("APPCODE " + idProperties.getAppCode()));
           headers.put("Content-Type", Collections.singletonList("application/x-www-form-urlencoded; charset=UTF-8"));
   
           HttpEntity<MultiValueMap<String, Object>> httpEntity = new HttpEntity<MultiValueMap<String, Object>>(paramMap, headers);
           ResponseEntity<String> response = restTemplate.exchange(idProperties.getUrl(), HttpMethod.POST, httpEntity, String.class);
           System.out.println(response.getStatusCode());
           System.out.println(response.getBody());
           if (response.getStatusCode() == HttpStatus.OK) {
               String body = response.getBody();
               JSONObject jsonObject = JSON.parseObject(body);
               int staus = jsonObject.getInteger("error_code");
               JSONObject result = jsonObject.getJSONObject("result");
               Boolean isok = result.getBoolean("isok");
   
               if (staus == 0 && isok) {
                   return true;
               }
           }
           return false;
       }
