使用asp.net C＃Javascript登录使用Finerprint的Asp.net Web应用程序
我想使用指纹登录我的asp.net Web应用程序。 这意味着我不想使用任何登录ID和密码。 我只想用我的指纹登录。 我有一个3米有说服力的设备，设备工作正常，但我不知道如何将设备与我的软件集成。 我正在使用ActiveX。
我的Javascript代码是：
$(document).ready(function () { $('#scan').click(function () { $('#dicscan').addClass('scanning'); setTimeout(function () { $('#dicscan').removeClass('scanning'); }, 20 * 1000); }); }); function OpenActiveX() { var port = document.getElementById("Comport"); port.Conopen = 1; if (port.error > 0) //Display errors if found alert(port.ErrorDescription); } function Matching() { var retval = 0; var port = document.getElementById("Comport"); port.Ksserialnumber = 1; port.KsCapture = 1; port.KsAuthenticationMatch = 1; retval = port.KsMatchretvalue; if (retval > 0) { alert("Two fingers are Matched..."); window.open('ResultPage.html', '_self'); } else { alert("Finger Not Matched..."); } if (port.error > 0) //Display errors if found alert(port.ErrorDescription); } 我在port.KsMatchretvalue中未定义。
我正在使用3M Cogent CSD 200型指纹读取器设备
希望您已经拥有SDK以下是此设备的一些代码，用于捕获和匹配详细信息以允许登录。
两个function在这里
1.]捕获 – 保存指纹
2.]匹配 – 在登录时匹配fingetprint
注意：它是我的应用程序中的代码块，您必须根据您的应用程序进行调整
