Java使用阿里云接口进行身份证实名认证的示例实现

如今随着互联网产业的多元化发展，尤其是互联网金融，O2O，共享经济等新兴商业形式的兴起，企业对实名认证业务的数据形式和数据质量有了更高的需求。如今也衍生出身份证实名认证业务，通过接口将身份证号码、姓名上传至阿里云，再与全国公民身份信息系统进行匹配，判断信息的一致性。

在使用接口服务的方面我推荐使用技术实力强大的阿里云；

首先点击：【阿里云API接口】获取相应的订单后在控制台中可以得到您的appcode；

发送数据：

bodys.put("idNo", "340421190210182345");
bodys.put("name", "张三");

返回数据：

{
 "name": "张三",
 "idNo": "340421190710145412",
 "respMessage": "身份证信息匹配",
 "respCode": "0000",
 "province": "安徽省",
 "city": "淮南市",
 "county": "凤台县",
 "birthday": "19071014",
 "sex": "M",
 "age": "111"
}

具体实现类：

public static void main(String[] args) {
    String host = "https://idenauthen.market.alicloudapi.com";
    String path = "/idenAuthentication";
    String method = "POST";
    String appcode = "你自己的AppCode";
    Map<String, String> headers = new HashMap<String, String>();
    //最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
    headers.put("Authorization", "APPCODE " + appcode);
    //根据API的要求，定义相对应的Content-Type
    headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
    Map<String, String> querys = new HashMap<String, String>();
    Map<String, String> bodys = new HashMap<String, String>();
    bodys.put("idNo", "340421190210182345");
    bodys.put("name", "张三");

    try {
      /**

      HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
      System.out.println(response.toString());
      //获取response的body
      //System.out.println(EntityUtils.toString(response.getEntity()));
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
