应用场景
在企业会员后台注册系统中，为验证企业名称是否输入完整且是有效存在的，则可以通过云API服务的方式进行验证及提取相关的基本信息，自动化提取的企业工商其它信息如法人、企业性质、经营地址等也可以提高录入效率和准确率。
本文将以阿里云提供的 API 服务，实现通过企业名称查询工商数据的功能。
关于阿里云企业工商数据查询API
官方介绍其每天更新全国企业、个体工商户的数据。
1. 注册阿里云账号。
2. 获取开发者 AppCode，后继开发会用到。
开发运行环境
操作系统： Windows Server 2019 DataCenter
.net版本： .netFramework4.0 或以上
开发工具：VS2019 C#
类设计
类 Company (企业类) 设计见下表：
类属性
类方法
queryName 和 queryName2 方法均可以查询（调用地址和方式不同，参数一致），调用均返回对应的类属性数据，参数见如下表格：
本方法返回 string 类型的对应属性值（如果成功的话）。
实现代码
创建 Company 类
public class Company
{
public string ResultJson="";
public string ErrorMessage = "";
public string creditCode = "";
public string faRen = "";
public string address = "";
public string bussinessDes = "";
public string regType = "";
public string regMoney = "";
public string bussiness = "";
public void queryName(string CompanyName)
{
String host = "http://qianzhan1.market.alicloudapi.com";
String path = "/CommerceAccurate";
String method = "GET";
String appcode = "您的AppCode";
String querys = "comName=" + System.Web.HttpUtility.UrlEncode(CompanyName);
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)
{
ErrorMessage = ex.Message;
httpResponse = (HttpWebResponse)ex.Response;
return;
}
Stream st = httpResponse.GetResponseStream();
StreamReader reader = new StreamReader(st, Encoding.GetEncoding("utf-8"));
ResultJson=(reader.ReadToEnd());
if (ResultJson.IndexOf("查询成功") == -1)
{
return;
}
Newtonsoft.Json.Linq.JObject jsonObj = Newtonsoft.Json.Linq.JObject.Parse(ResultJson);
creditCode = jsonObj["result"]["creditCode"].ToString();
faRen = jsonObj["result"]["faRen"].ToString();
address = jsonObj["result"]["address"].ToString();
bussinessDes = jsonObj["result"]["bussinessDes"].ToString();
regType = jsonObj["result"]["regType"].ToString();
regMoney = jsonObj["result"]["regMoney"].ToString();
bussiness = jsonObj["result"]["bussiness"].ToString();
}
public void queryName2(string CompanyName)
{
//Zm1qSqdjl2296ixnA6ODXpglwQKYxkSD
String host = "https://cardnotwo.market.alicloudapi.com";
String path = "/company";
String method = "POST";
String appcode = ""您的AppCode";";
String querys = "com=" + System.Web.HttpUtility.UrlEncode(CompanyName);
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)
{
ErrorMessage = ex.Message;
httpResponse = (HttpWebResponse)ex.Response;
return;
}
Stream st = httpResponse.GetResponseStream();
StreamReader reader = new StreamReader(st, Encoding.GetEncoding("utf-8"));
ResultJson = (reader.ReadToEnd());
if (ResultJson.IndexOf("查询成功") == -1)
{
return;
}
Newtonsoft.Json.Linq.JObject jsonObj = Newtonsoft.Json.Linq.JObject.Parse(ResultJson);
creditCode = jsonObj["result"]["creditCode"].ToString();
faRen = jsonObj["result"]["faRen"].ToString();
address = jsonObj["result"]["address"].ToString();
bussinessDes = jsonObj["result"]["bussinessDes"].ToString();
regType = jsonObj["result"]["regType"].ToString();
regMoney = jsonObj["result"]["regMoney"].ToString();
bussiness = jsonObj["result"]["bussiness"].ToString();
}
}调用举例
调用判断是否返回社会统一信用代码，示例代码如下：
Company cp = new Company();
cp.queryName2("天津XXXX数码有限公司");
if (cp.creditCode != "")
{
Response.Write("社会统一信用代码：" + cp.creditCode + "<br>");
Response.Write("法人：" + cp.faRen + "<br>");
Response.Write("注册地址：" + cp.address + "<br>");
Response.Write("营业范围：" + cp.bussinessDes + "<br>");
Response.Write("企业性质：" + cp.regType + "<br>");
Response.Write("注册资金：" + cp.regMoney + "<br>");
Response.Write("营业期限：" + cp.bussiness + "<br>");
}
else
{
Response.Write("错误信息：" + cp.ErrorMessage + "<br>");
Response.Write("JSON返回信息：" + cp.ResultJson + "<br>");
}小结
调用云接口服务需要费用，我们需要根据实际应用进行成本考虑，官方说明如果查询失败则不扣除费用，具体内容可参考本文第二小节关于阿里云企业工商数据查询API中的链接。
