一、什么是VIN码车辆识别码解析接口

输入17位vin码，获取到车辆的品牌、型号、出厂日期、发动机类型、驱动类型、车型、年份等信息。无论是汽车电商平台、二手车商、维修厂，还是保险公司、金融机构，都能通过接入该API实现信息自动化、决策智能化和服务标准化。

二、如何用C#进行调用？

            }

            if (host.Contains("https://"))

            }
            httpRequest.Method = method;
            httpRequest.Headers.Add("Authorization", "APPCODE " + appcode);
            if (0 < bodys.Length)
            {

                }
            }
            try
            {

            }
            catch (WebException ex)
            {
                httpResponse = (HttpWebResponse)ex.Response;
            }

            Console.WriteLine(httpResponse.StatusCode);

            Console.WriteLine(reader.ReadToEnd());
            Console.WriteLine("\n");

        }

        public static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
        {
            return true;
        }
