ASP.NET程序读取二代身份证（附源码）

原文:ASP.NET程序读取二代身份证（附源码）

一般来说winform应用程序解决这个问题起来时很容易的，web应用程序就麻烦一点了。

这里我说说我的解决思路：

一、你必要有联机型居民身份证阅读器一个（带驱动光盘），这里我用的是精伦电子公司的iDR200,并有这个阅读器的开发接口说明。

二、新建一个winform控件项目ReadCardControl，添加一个主类ReadCard

1、  声明dll入口

[DllImport("Sdtapi.dll")]

private static extern int InitComm(int iPort);//初始化

[DllImport("Sdtapi.dll")]

private static extern int Authenticate();//卡认证

[DllImport("Sdtapi.dll")]

private static extern int ReadBaseInfos(StringBuilder Name, StringBuilder Gender, StringBuilder Folk, StringBuilder BirthDay, StringBuilder Code, StringBuilder Address, StringBuilder Agency, StringBuilder ExpireStart, StringBuilder ExpireEnd);//读取数据，推荐使用

[DllImport("Sdtapi.dll")]

private static extern int CloseComm();//关闭端口

[DllImport("Sdtapi.dll")]

private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//读取数据，这里不用

[DllImport("Sdtapi.dll")]

private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//读取数据，这里不用

[DllImport("kernel32.dll")]

private static extern int Beep(int dwFreq, int dwDuration);//用来大吼一声

2、读卡方法

private string[] arrys = null;//声明用来保存身份证信息的数组

public void OnTimer()

{

StringBuilder Name = new StringBuilder(31);

StringBuilder Gender = new StringBuilder(3);

StringBuilder Folk = new StringBuilder(10);

StringBuilder BirthDay = new StringBuilder(9);

StringBuilder Code = new StringBuilder(19);

StringBuilder Address = new StringBuilder(71);

StringBuilder Agency = new StringBuilder(31);

StringBuilder ExpireStart = new StringBuilder(9);

StringBuilder ExpireEnd = new StringBuilder(9);

//int len = 0;

//string[] temp;

char[] param = { '\0' };

byte[] pMsg = new byte[256];

string[] baseinfo = new string[9];

//打开端口

int intOpenRet = InitComm(1001);

if (intOpenRet != 1)

{

//SetText("阅读机具未连接", lblMsg);

return;

}

//卡认证

int intReadRet = Authenticate();

if (intReadRet != 1)

{

//SetText("卡认证失败", lblMsg);

CloseComm();

return;

}

//ReadBaseInfos（推荐使用）

int intReadBaseInfosRet = ReadBaseInfos(Name, Gender, Folk, BirthDay, Code, Address, Agency, ExpireStart, ExpireEnd);

if (intReadBaseInfosRet != 1)

{

//SetText("读卡失败", lblMsg);

CloseComm();

return;

}

Beep(2047, 200);

arrys = new string[10];

arrys[0] = Code.ToString().Trim();

arrys[1] = Name.ToString().Trim();

arrys[2] = Gender.ToString().Trim();

arrys[3] = Folk.ToString().Trim();

arrys[4] = BirthDay.ToString().Trim();

arrys[5] = Address.ToString().Trim();

arrys[6] = Agency.ToString().Trim();

arrys[7] = ExpireStart.ToString().Trim();

arrys[8] = ExpireEnd.ToString().Trim();

arrys[9] = System.IO.Directory.GetCurrentDirectory() + "\\photo.bmp";

//SetText("读卡成功", lblMsg);

//SetText("证件号码：" + Code.ToString(), label1);

//SetText("姓名：" + Name.ToString(), label2);

//SetText("性别：" + Gender.ToString(), label3);

//SetText("民族：" + Folk.ToString(), label4);

//SetText("出生日期：" + BirthDay.ToString(), label5);

//SetText("地址：" + Address.ToString(), label6);

//SetText("签发机关：" + Agency.ToString(), label7);

//SetText("签发时间：" + ExpireStart.ToString(), label8);

//SetText("有效截止时间：" + ExpireEnd.ToString(), label9);

SetImage("photo.bmp", pictureBox1);

CloseComm();

}

2、  声明一个客户端调用的方法Test（这里没有直接用数组）

public string Test()

{

string str = "";

foreach (string s in arrys)

{

str += s + ",";

}

str = str.TrimEnd(',');

return str;

}

三、将这个控件封装成activex组件

在ReadCard类的头部添加

[Guid("B9BB196C-5008-4156-840F-9FE37BA81502")]

若要实现客户端访问服务器端数据，则必须实现IObjectSafe接口

接口声明如下：

[ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]

[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]

public interface IObjectSafe

{

[PreserveSig]

void GetInterfaceSafeOptions(ref Guid id, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

[PreserveSig()]

void SetInterfaceSafeOptions(ref Guid id, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);

}

UI设计

);
            ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();
            this.ResumeLayout(false);

        }

        #endregion

        private System.Windows.Forms.PictureBox pictureBox1;

四、新建一个web应用程序项目

1、界面：

<table style="width:100%;" border="1" width="100%" bordercolordark="#FFFFFF" cellspacing="0" cellpadding="2" bordercolor="#000000">

<tr>

<td style="width:33.3%; text-align: right;">证件号码：</td>

<td style="width:33.3%" id="td1">&nbsp;</td>

<td style="width:33.3%; text-align: left;" rowspan="6">

<object id="csharpActiveX" name="csharpActiveX" classid="clsid:B9BB196C-5008-4156-840F-9FE37BA81502"></object></td>

</tr>

<tr>

<td style="text-align: right">姓名：</td>

<td id="td2">&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">性别：</td>

<td id="td3">&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">民族：</td>

<td id="td4">&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">出生日期：</td>

<td id="td5">&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">地址：</td>

<td id="td6">&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">签发机关：</td>

<td id="td7">&nbsp;</td>

<td>&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">签发时间：</td>

<td id="td8">&nbsp;</td>

<td>&nbsp;</td>

</tr>

<tr>

<td style="text-align: right">有效截止时间：</td>

<td id="td9">&nbsp;</td>

<td>&nbsp;</td>

</tr>

</table>

2、Javascript代码：

function Demo() {

try {

var x = document.getElementById("csharpActiveX");

x.OnTimer();//读取图片

var v = x.Test();//读取身份证其他信息

var arrys = v.split(',');

if (arrys.length > 9) {

document.getElementById("td1").innerHTML = arrys[0];

document.getElementById("td2").innerHTML = arrys[1];

document.getElementById("td3").innerHTML = arrys[2];

document.getElementById("td4").innerHTML = arrys[3];

document.getElementById("td5").innerHTML = arrys[4];

document.getElementById("td6").innerHTML = arrys[5];

document.getElementById("td7").innerHTML = arrys[6];

document.getElementById("td8").innerHTML = arrys[7];

document.getElementById("td9").innerHTML = arrys[8];

}

}

catch (e) {

//alert(e.message)

}

}

秒钟读取一次
