一：前言
設備已經安裝好100UC的USB驅動，設備能正常工作
二：獲取數據介紹
通過調取sdk接口獲取數據，sdk同http模式不同，初始化完成以后，然后使用 CVR_Authenticate 來確認是否存在身份證，如果存在則去獲取身份證信息通過事件反饋給客戶端上層，程序讀取完一次后 sdk 關閉了數據獲取，需要手動拿起身份證卡片后才能再次確認身份證是否存在，限制了讀卡次數。開發包還提供和 http 相同的模式，初始化完成以后，使用 CVR_AuthenticateForNoJudge 關閉身份證驗證，則可以一直讀取身份證信息，取消讀卡次數，無需拿起再放下。
三：反饋客戶端身份證信息 IDCardNetSDK 類模塊代碼包含下面三部分
1.先用C#翻譯C++的接口
public class ClientInterfance { /// <summary> /// 用於第二代居民身份證閱讀器連接 /// </summary> /// <param name="Port">端口編號：連接串口(com1~com16)或者usb口(1001~1016)</param> /// <returns>1:正確,2:端口打開失敗,-1:未知錯誤,-2:動態庫加載失敗</returns> [DllImport("termb.dll")] public static extern int CVR_InitComm(int Port); /// <summary> /// 讀卡器和卡片之間的合法身份確認，卡循環間隔大於300ms。若卡片放置后認證失敗，重新放置。 /// </summary> /// <returns>1:卡片認證成功,2:尋卡失敗,3:選卡失敗,4:未連接讀卡器,0:動態庫未加載</returns> [DllImport("termb.dll")] public static extern int CVR_Authenticate(); /// <summary> /// 關閉卡片身份確認，使卡片可以一直讀，此函數只返回1. /// </summary> /// <returns></returns> [DllImport("termb.dll")] public static extern int CVR_AuthenticateForNoJudge(); /// <summary> /// 通過閱讀器從第二代居民身份證讀取信息。卡認證成功一候才可讀卡操作，讀卡完畢若繼續讀卡應移走二代證卡片重新放置做卡認證 /// </summary> /// <returns>1:正確,0:錯誤，讀取失敗,4:讀卡器未連接,99:動態庫未加載</returns> [DllImport("termb.dll")] public static extern int CVR_Read_FPContent(); /// <summary> /// 關閉pc到閱讀器的連接 /// </summary> /// <returns>1:關閉成功,0:端口號不合法,-1:端口已經關閉,-2動態庫加載失敗</returns> [DllImport("termb.dll")] public static extern int CVR_CloseComm(); /// <summary> /// 得到姓名信息 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetPeopleName(ref byte strTmp,ref int strLen); /// <summary> /// 得到性別信息 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetPeopleSex(ref byte strTmp, ref int strLen); /// <summary> /// //得到民族信息 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetPeopleNation(ref byte strTmp, ref int strLen); /// <summary> /// 得到出生日期 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetPeopleBirthday(ref byte strTmp, ref int strLen); /// <summary> /// 得到地址信息 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetPeopleAddress(ref byte strTmp, ref int strLen); /// <summary> /// 得到卡號信息 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetPeopleIDCode(ref byte strTmp, ref int strLen); /// <summary> /// 得到發證機關信息 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetDepartment(ref byte strTmp, ref int strLen); /// <summary> /// 得到有效開始日期 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetStartDate(ref byte strTmp, ref int strLen); /// <summary> /// 得到有效截止日期 /// </summary> /// <param name="strTmp"></param> /// <param name="strLen"></param> /// <returns></returns> [DllImport("termb.dll")] public static extern int GetEndDate(ref byte strTmp, ref int strLen); }
2.設備初始化、檢查卡片合法性、是否讀取卡片、讀取卡片
public bool isIniCoom() { for (int i = 1001; i <= 1016; i++) { if(ClientInterfance.CVR_InitComm(i) == 1) { return true; } } return false; } public bool isAuthen() { if (ClientInterfance.CVR_Authenticate() == 1) { return true; } return false; } public bool isReadCont() { if (ClientInterfance.CVR_Read_FPContent() == 1) { return true; } return false; } public void isReaded() { IDCardMessage idcard = new IDCardMessage(); byte[] name = new byte[30]; int length = 30; ClientInterfance.GetPeopleName(ref name[0], ref length); idcard.Name = Encoding.GetEncoding("GB2312").GetString(name).Replace("\0", "").Trim(); byte[] sex = new byte[30]; length = 3; ClientInterfance.GetPeopleSex(ref sex[0], ref length); idcard.Sex = Encoding.GetEncoding("GB2312").GetString(sex).Replace("\0", "").Trim(); byte[] people = new byte[30]; length = 3; ClientInterfance.GetPeopleNation(ref people[0], ref length); idcard.National = Encoding.GetEncoding("GB2312").GetString(people).Replace("\0", "").Trim(); byte[] birthday = new byte[30]; length = 16; ClientInterfance.GetPeopleBirthday(ref birthday[0], ref length); idcard.BirthDay = Encoding.GetEncoding("GB2312").GetString(birthday).Replace("\0", "").Trim(); byte[] address = new byte[30]; length = 70; ClientInterfance.GetPeopleAddress(ref address[0], ref length); idcard.Address = Encoding.GetEncoding("GB2312").GetString(address).Replace("\0", "").Trim(); byte[] number = new byte[30]; length = 36; ClientInterfance.GetPeopleIDCode(ref number[0], ref length); idcard.IdentityId = Encoding.GetEncoding("GB2312").GetString(number).Replace("\0", "").Trim(); byte[] signdate = new byte[30]; length = 30; ClientInterfance.GetDepartment(ref signdate[0], ref length); idcard.Gov = Encoding.GetEncoding("GB2312").GetString(signdate).Replace("\0", "").Trim(); byte[] validtermOfStart = new byte[30]; length = 16; ClientInterfance.GetStartDate(ref validtermOfStart[0], ref length); idcard.StartDate = Encoding.GetEncoding("GB2312").GetString(validtermOfStart).Replace("\0", "").Trim(); byte[] validtermOfEnd = new byte[30]; length = 16; ClientInterfance.GetEndDate(ref validtermOfEnd[0], ref length); idcard.EndDate = Encoding.GetEncoding("GB2312").GetString(validtermOfEnd).Replace("\0", "").Trim(); IDCardChangeNotify(this, new MyEventArgs(idcard)); }
3.事件反饋
public event EventHandler<MyEventArgs> IDCardChangeNotify; public class MyEventArgs : EventArgs { IDCardMessage _msg; public MyEventArgs(IDCardMessage msg) { this._msg = msg; } public IDCardMessage Msg { get { return _msg; } } } public class IDCardMessage { public string Name { get; set; } public string Sex { get; set; } public string National { get; set; } public string BirthDay { get; set; } public string Address { get; set; } public string IdentityId { get; set; } public string Gov { get; set; } public string StartDate { get; set; } public string EndDate { get; set; } }
4.開啟任務獲取數據方法
public void GetIDCard() { CancellationTokenSource cancelTokenSource = new CancellationTokenSource(); cancelTokenSource.Token.Register(()=> { ClientInterfance.CVR_CloseComm(); }); Task.Factory.StartNew(() => { while (!cancelTokenSource.IsCancellationRequested) { Console.WriteLine("1.即將初始化設備"); if(isIniCoom()) { Console.WriteLine("2.即將檢查卡片合法性"); if (isAuthen()) { Console.WriteLine("3.即將准備讀取"); if (isReadCont()) { isReaded(); } else { ClientInterfance.CVR_CloseComm(); Console.WriteLine("3.讀取卡片失敗，已關閉接口調用"); } } else { ClientInterfance.CVR_CloseComm(); Console.WriteLine("2.檢查卡片合法性失敗，已關閉接口調用"); } } else { ClientInterfance.CVR_CloseComm(); Console.WriteLine("初始化失敗，已關閉接口調用"); } Thread.Sleep(500); } }, cancelTokenSource.Token); }
四：客戶端調用我的模塊
static void Main(string[] args) { IDCardNetSDK Evet = new IDCardNetSDK(); Evet.IDCardChangeNotify += IDCardSDKCallBack; Evet.GetIDCard(); Console.ReadKey(); } private static void IDCardSDKCallBack(object sender, IDCardNetSDK.MyEventArgs e) { Console.WriteLine("狀態改變:" + e.Msg.IdentityId.ToString()); }
PS: 如果我們在使用的過程中插拔設備，而我們的代碼在 初始化設備 、檢查卡片合法性、讀卡等動作中失敗了，一定要加一句 CVR_CloseCommn 關閉設備。
