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

            }
}

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>");
}

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。
