一、什么是商品条码查询接口？
1974年6月26日，美国俄亥俄州的一家超市首次使用商品条码完成结算，标志着商品条码正式进入商业应用领域。这项技术通过自动识别和数据采集，极大提升了零售行业的作业效率，减少了人工录入错误，提高了库存管理水平。
如今，商品条码已成为商品在全球流通中的“唯一身份标识”，而商品条码查询接口正是基于这一基础技术，为用户提供快速获取商品信息的能力。用户只需输入13位或14位商品条码，即可获取包括商品名称、品牌、规格、价格、保质期、成分信息等关键数据，广泛服务于消费者、零售商、电商平台、物流企业等多个群体。
二、商品条形码查询接口如何用C#进行调用？
下面我们以阿里云的接口为例，具体代码示例如下：
接口地址：https://market.aliyun.com/apimarket/detail/cmapi00065867
//using System.IO;
//using System.Text;
//using System.Net;
//using System.Net.Security;
//using System.Security.Cryptography.X509Certificates;private const String host = "https://tsbarcode.market.alicloudapi.com";private const String path = "/barcode/index";private const String method = "GET";private const String appcode = "你自己的AppCode";static void Main(string[] args){String querys = "barcode=6921830106820";String bodys = "";String url = host + path;HttpWebRequest httpRequest = null;HttpWebResponse httpResponse = null;if (0 < querys.Length){url = url + "?" + querys;}if (host.Contains("https://")){ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);httpRequest = (HttpWebRequest)WebRequest.CreateDefault(new Uri(url));}else{httpRequest = (HttpWebRequest)WebRequest.Create(url);}httpRequest.Method = method;httpRequest.Headers.Add("Authorization", "APPCODE " + appcode);if (0 < bodys.Length){byte[] data = Encoding.UTF8.GetBytes(bodys);using (Stream stream = httpRequest.GetRequestStream()){stream.Write(data, 0, data.Length);}}try{httpResponse = (HttpWebResponse)httpRequest.GetResponse();}catch (WebException ex){httpResponse = (HttpWebResponse)ex.Response;}Console.WriteLine(httpResponse.StatusCode);Console.WriteLine(httpResponse.Method);Console.WriteLine(httpResponse.Headers);Stream st = httpResponse.GetResponseStream();StreamReader reader = new StreamReader(st, Encoding.GetEncoding("utf-8"));Console.WriteLine(reader.ReadToEnd());Console.WriteLine("\n");}public static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors){return true;}
返回代码如下：
