Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

## 身份证阅读器和指纹识别工具包

Readme

tyidcard-npm-sdk

身份证阅读器和指纹识别工具包

兼容 Windows 32 位和 64 位系统,支持大部分身份证阅读器。
开发包由广东东信智能科技有限公司提供。

公安部身份证阅读器模块SAM通讯协议

安装

npm install @gdty/tyidcard-npm-sdk

使用示例

// 加载身份证阅读器 DLL
Sdtapi.load('D:\\IdeaProjects\\tyidcard-npm-sdk\\sdtapi_x64.dll');

// 打开端口
let res = Sdtapi.SDT_OpenPort();
if (Constant.RESULT.OK != res) {
    console.error("打开端口......失败");
    return;
}

// 开始寻找身份证卡
res = Sdtapi.SDT_StartFindIDCard();
if (Constant.RESULT.FIND_SUCCESS != res) {
    console.error("正在找卡......失败");
    return;
} else {
    console.log("找卡成功");
}

// 选择身份证卡
res = Sdtapi.SDT_SelectIDCard();
if (Constant.RESULT.OK != res) {
    console.error("正在选卡......失败");
    return;
}

// 读取身份证基本信息
res = Sdtapi.SDT_ReadBaseFPMsg();
if (Constant.RESULT.OK != res.res) {
    res = Sdtapi.SDT_ReadBaseMsg();
    if (Constant.RESULT.OK != res.res) {
        console.error("正在读取基本信息......失败");
        return;
    }
}

console.log(res);

// 解压照片信息
DllFile.load('D:\\IdeaProjects\\tyidcard-npm-sdk\\DLL_File.dll');
let packres = DllFile.unpack(res.photomsg, 1);
console.log(packres);

// 提取指纹信息
let fp = FpUtils.getFp(res.fpmsg);
console.log('----------------------------------');
console.log(fp);

// 加载指纹识别 DLL
Fprapi.load('D:\\IdeaProjects\\tyidcard-npm-sdk\\ID_Fpr.dll');
FprCapapi.load('D:\\IdeaProjects\\tyidcard-npm-sdk\\ID_FprCap.dll');

// 初始化指纹采集
let cpres = FprCapapi.LIVESCAN_Init();
console.log('LIVESCAN_Init:' + cpres);

// 开始采集指纹
cpres = FprCapapi.LIVESCAN_BeginCapture(0);
console.log('LIVESCAN_BeginCapture:' + cpres);

// 获取原始指纹数据
let ckpres = FprCapapi.LIVESCAN_GetFPRawData(0);
console.log(ckpres);

// 获取指纹图像数据
console.log('---------------------------------------');
let cbpres = FprCapapi.LIVESCAN_GetFPBmpData(0);
console.log(cbpres);

// 结束采集
cpres = FprCapapi.LIVESCAN_EndCapture(0);
console.log('LIVESCAN_EndCapture:' + cpres);

// 获取指纹模块版本
let fpres = Fprapi.FP_GetVersion();
console.log('FP_GetVersion:' + fpres);

// 初始化指纹识别
fpres = Fprapi.FP_Begin();
console.log('FP_Begin:' + fpres);

// 指纹匹配
fpres = Fprapi.FP_ImageMatch(ckpres.msg, fp.second);
console.log('FP_ImageMatch:' + fpres.res);

主要模块

  • Sdtapi: 身份证阅读器接口,用于打开端口、查找和选择身份证卡、读取身份证信息。
  • Fprapi: 指纹识别接口,用于获取指纹模块版本、初始化指纹识别、进行指纹匹配。
  • FprCapapi: 指纹采集接口,用于初始化采集、开始和结束采集、获取指纹数据。
  • DllFile: 用于加载 DLL 文件并解压身份证照片信息。
  • FpUtils: 工具类,用于提取指纹信息。
  • Constant: 常量定义,如端口状态、结果代码等。

注意事项

  • 确保正确加载所需的 DLL 文件。
  • 身份证阅读器和指纹识别模块需要物理连接并正常工作。
  • 根据系统架构(x86/x64)选择合适的 DLL 文件。
