一、什么是车架号查询车牌号接口？

       车架号查询车牌号接口，即传入车架号，返回车牌号、车型编码、初次登记日期信息。车架号又称车辆VIN码，车辆识别码。

二、如何用Java对接该接口？

下面我们以阿里云接口为例，具体Java示例代码如下：

接口地址：https://market.aliyun.com/apimarket/detail/cmapi00070054#sku=yuncode6405400009public static void main(String[] args) {String host = "https://kzcarn.market.alicloudapi.com";String path = "/api/car/license/query";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 83359fd73fe94948385f570e3c139105headers.put("Authorization", "APPCODE " + appcode);//根据API的要求，定义相对应的Content-Typeheaders.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("vin", "LGXC74C43P0250893");try {/*** 重要提示如下:* HttpUtils请从* https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/src/main/java/com/aliyun/api/gateway/demo/util/HttpUtils.java* 下载** 相应的依赖请参照* https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/pom.xml*/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();}}

返回结果如下：

{"msg": "成功","success": true,"code": 200,"data": {"vinCode": "LGXC74C43P0250893","regDate": "2023-07-16","vehicleCode": "BYD6470ST6HEV11","plateNumber": "浙AG58092"}
}
VinCode	车架号
PlateNumber	车牌号
VehicleCode	车型编码
RegDate	初次登记日期
