mvc+EF实现简单的登陆功能
EF采用DatabaseFirst的方式处理数据
新建一个LoginController
[HttpGet] public ActionResult Login() { var UserName = Request.Cookies["UserName"] == null ? "" : Request.Cookies["UserName"].Value; ViewBag.UserName = UserName; return View(); } public JsonResult CheckUserLogin(UserInfo userInfo) { using (EasyUIDemoDBEntities db = new EasyUIDemoDBEntities()) { //linq查询 var users = from p in db.UserInfo where p.Name == userInfo.Name && p.Password == userInfo.Password && p.Enable == true select p; if (users.Count() > 0) { userInfo = users.FirstOrDefault(); return Json(new { result = "success", content = "" }); } else { return Json(new { result = "error", content = "用户名密码错误，请您检查" }); } } }
view视图
<html><head> <meta name="viewport" content="width=device-width" /> <title>Login</title> <script src=http://www.mamicode.com/"~/Scripts/jquery-1.7.1.min.js"></script> <script type="text/javascript"> //异步实现用户的登录 function LoginUserInfo() { $.ajax({ url: "../Login/CheckUserLogin", type: "POST", dataType: "json", data: { "Name": $("#UserName").val(), "Password": $("#Password").val() }, success: function (data) { if (data.result == "success") { //window.location.href = http://www.mamicode.com/"Home/GetView?viewPara=Index";>//window.location.href = http://www.mamicode.com/"@Url.Content("/Home/Index/")"; alert(‘success‘); //window.location.href = http://www.mamicode.com/"/Home/Index"; } else { alert(data.content); //window.location.href = http://www.mamicode.com/"/Login/Login/"; } }, error: function (xhr, error, ex) { alert("erroraaaaa"); window.location.href = "/Login/Login/"; } }); } </script></head><body> <div id="AddUserDialog" style="width: 300px; height: 160px; padding: 10px 20px" title="EasyUIDemo用户登录" > <form id="ff"> <table id="tblAdd"> <tr> <td> <label for="UserName">用户名：</label></td> <td> <input type="text" id="UserName" name="UserName" value=http://www.mamicode.com/"@ViewBag.UserName" /></td> <td> </tr> <tr> <td> <label for="Password">密 码：</label></td> <td> <input type="text" id="Password" name="Password" /></td> </tr> <tr> <td colspan="2" style="text-align: center; padding-top: 10px"> <input type="button" value=http://www.mamicode.com/"提交" id="btnLogin" onclick="LoginUserInfo();"/> </td> </tr> </table> </form> </div></body></html>
注意：在AJAX中提交地址如果在controller中不定义[httpget],则会访问第一个Loing的eAction
