一、什么是商品條碼查詢接口？
1974年6月26日，美國俄亥俄州的一家超市首次使用商品條碼完成結算，標志著商品條碼正式進入商業應用領域。這項技術通過自動識別和數據采集，極大提升了零售行業的作業效率，減少了人工錄入錯誤，提高了庫存管理水平。
如今，商品條碼已成為商品在全球流通中的“唯一身份標識”，而商品條碼查詢接口正是基于這一基礎技術，為用戶提供快速獲取商品信息的能力。用戶只需輸入13位或14位商品條碼，即可獲取包括商品名稱、品牌、規格、價格、保質期、成分信息等關鍵數據，廣泛服務于消費者、零售商、電商平臺、物流企業等多個群體。
二、商品條形碼查詢接口如何用C#進行調用？
下面我們以阿里云的接口為例，具體代碼示例如下：
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;}
返回代碼如下：
