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=yuncode6405400009


	public 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 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("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
