Asp.net MVC读取身份证信息支持任何浏览器插件使用WebSocket技术
1、思路：在使用浏览器的电脑上装一个websocket服务端。通过读取浏览器的操作通知给服务端，服务端触发读取身份证机制。
2、服务端处理完通知给浏览器，这样就实现了任何浏览器都可以读取身份证。
具体代码如下：
浏览器端：
服务端代码如下：
1、因为要做windows服务需要安装Topshelf;
2、因为要做websocket需要nuget包Fleck，为啥选择该包，因为该websocket遇到错误可以自己重新启动。
3、控制台程序Program.cs代码如下
using Fleck;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Topshelf;
namespace IDCardReader
{

{
private static NLog.Logger logger = NLog.LogManager.GetLogger("websocketserver");
static void Main(string[] args)
{
try
{
var rc = HostFactory.Run(x =>
{
x.Service(s =>
{
s.ConstructUsing(name => new Program());
s.WhenStarted(p => p.Start());
s.WhenStopped(p => p.Stop());
});
x.RunAsLocalSystem();
x.SetServiceName("MyShenIDCardServices");
x.SetDisplayName("身份证读卡器插件");
});
var exitCode = (int)Convert.ChangeType(rc, rc.GetTypeCode());
Environment.ExitCode = exitCode;
}
catch (Exception ex)
{
logger.Error(ex.Message);
}
}

4、对接的是华视读卡器HuaShiIDCardReader.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;

public class HuaShiIDCardReader
{
//初始化
static int iRetUSB = 0;
public static void OpenReader()
{
try
{
if(iRetUSB!=1)
{
int iPort = 0;
for (iPort = 1001; iPort <= 1016; iPort++)
{
iRetUSB = CVRSDK.CVR_InitComm(iPort);
if (iRetUSB == 1)
{
break;
}
}
}
}
catch (Exception)
{
}
}
//public static string ReadCard()
//{

public static string ReadCard()
{

finally
