準備工作
gt.js文件 jquery-1.7.1min.js或更高版本
1、 js驗證及 獲取驗證碼
<script type="text/javascript">
window.addEventListener('load', processGeeTest);
function processGeeTest() {
$.ajax({
// 獲取id，challenge，success（是否啓用failback）
url: "/Login/GeekTest",
type: "get",
dataType: "json", // 使用jsonp格式
success: function (data) {
// 使用initGeetest接口
// 參數1：配置參數，與創建Geetest實例時接受的參數一致
// 參數2：回調，回調的第一個參數驗證碼對象，之後可以使用它做appendTo之類的事件
initGeetest({
gt: data.gt,
challenge: data.challenge,
product: "float", // 產品形式
offline: !data.success
},
handler);
}
});

public ActionResult Index()

[HttpPost]
//登錄 根據登錄的用戶名和密碼查詢是否有該角色 並且驗證碼必須正確 跳到主頁
