<title>ajax Request </title>
<link type= "Text/css" rel= "stylesheet" href= "/content/style.css"/>

Controller
Copy Code code as follows:
Using System;
Using System.Collections.Generic;
Using System.Linq;
Using System.Web;
Using SYSTEM.WEB.MVC;
Using System.Text;
Namespace Bigtree. Controllers
{
Using Bigtree. Models;
Using Bigtree. Model;
Using Bigtree.lib;
Using System.Net.Mail;
Using System.Text.RegularExpressions;
public class Logincontroller:controller

{
return View ();
}
<summary>
Check Login
</summary>
<param name= "F" ></param>
<returns></returns>
[HttpPost]
Public ActionResult Checklogininfo (formcollection f)
{
Try
{
Post:user, PWD, remembered
String user = f["user"]. Trim ();
string pwd = f["pwd"]. Trim ();
String remembered = f["remembered"]. Trim ();
Jsonresult res = new Jsonresult ();
if (string. IsNullOrEmpty (user) | | String. IsNullOrEmpty (PWD))
{
Res. Data = new {status = 0};
}
MD5 Encrypted password
PWD = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile (pwd, "MD5"). ToLower ();
Reading from a database
Common.webuser account = Memberinfoservice.getmemberidforcheck (user, PWD);
if (account = = null)
{
Res. Data = new {status = 0};
}
Else
{
{status:1 (Success)/0 (fail),}
Res. Data = new {status = 1};
TODO: Login successful, log logged in user information save login status
Funsession.setsession (account);
Do you remember to log in
if (remembered = "on")
{
HttpCookie cookie = new HttpCookie ("Logininfo", account. Id.tostring ());
3 days effective
Cookie. Expires.adddays (3);
RESPONSE.COOKIES.ADD (cookie);
}
Else
{
HttpCookie cookie = new HttpCookie (account. Id.tostring (), account. Id.tostring ());
Make invalid
Cookie. Expires.addyears (-1);
RESPONSE.COOKIES.ADD (cookie);
}
}
return res;
}
catch (Exception ex)
{
Throw ex. innerexception;
}
}
}
}
I hope this article will be described to you. NET program design helps.
