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。

更多信息内容请参照:https://market.aliyun.com/products/57000002/cmapi029998.html?spm=5176.21213303.J_qCOwPWspKEuWcmp8qiZNQ.32.3ec42f3dzQ6CjW&scm=20140722.S_market@@%E6%95%B0%E6%8D%AE%E4%B8%8EAPI@@cmapi029998._.ID_market@@%E6%95%B0%E6%8D%AE%E4%B8%8EAPI@@cmapi029998-RL_%E4%BC%81%E4%B8%9A%E5%B7%A5%E5%95%86%E6%95%B0%E6%8D%AEapi%E6%8E%A5%E5%8F%A3-LOC_llm-OR_ser-V_3-RE_new2-P0_0#sku=yuncode2399800001开发前请准备如下操作:

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

序号属性名类型说明
1ErrorMessagestring发生任何异常返回的错误信息
2ResultJsonstring请求返回结果Json完整数据
3creditCodestring社会统一信用代码
4faRenstring法人
5addressstring注册地址
6bussinessDesstring经营范围
7regTypestring公司类型
8regMoneystring注册资金
9bussinessstring营业期限

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:

序号参数名类型说明
1CompanyNamestring传递完整的企业名称

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。
