企业三要素如何用C#实现调用

一、什么是企业三要素？

企业三要素即传入的企业名称、法人名称、社会统一信用代码或注册号，校验此三项是否一致。

二、具体怎么样通过C#实现接口调用？

下面我们以阿里云的为例，通过C#语言实现接口调用：

首先，注册阿里云账号，其次，找到对应接口链接，再次，选择免费试用，最后，调试成功后再选取套餐包。

//using System.IO;
//using System.Text;
//using System.Net;
//using System.Net.Security;
//using System.Security.Cryptography.X509Certificates;

        private const String host = "https://kzcpthree.market.alicloudapi.com";
        private const String path = "/company_three/check";
        private const String method = "POST";
        private const String appcode = "你自己的AppCode";

        static void Main(string[] args)
        {
            String querys = "";
            String bodys = "creditCode=creditCode&companyName=companyName&legalPerson=legalPerson";
            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);
            //根据API的要求，定义相对应的Content-Type
            httpRequest.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
            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;
        }

正确返回示例如下：

{
    "msg": "成功",
    "success": true,
    "code": 200,
    "data": {
        "result": 2, //1一致，2不一致
        "orderNo": "202412012048184836138",
        "companyName": true,   //true 正确， false 错误
        "legalPerson": false,
        "creditNo": true
    }
}
