1.用户登录
先看一下解决方案
接下来我们建一个名为Users的Model
public class Users
{
public Users()
{ }
[Key]
[DisplayName("编号")]
public int Id { get; set; }
[DisplayName("用户名")]
[Required(ErrorMessage = "用户名不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string Name { get; set; }
[DisplayName("密码")]
[Required(ErrorMessage = "密码不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string Password { get; set; }
[DisplayName("姓名")]
[Required(ErrorMessage = "姓名不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string RealName { get; set; }
[DisplayName("级别")]
[Required(ErrorMessage = "级别不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string RankId { get; set; }
[DisplayName("管理用户？")]
[Required(ErrorMessage = "管理用户？不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string IsPower { get; set; }
[DisplayName("是否激活")]
[Required(ErrorMessage = "是否激活不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string IsActive { get; set; }
[DisplayName("所属地区")]
[Required(ErrorMessage = "所属地区不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string RegionId { get; set; }
[DisplayName("手机号")]
[Required(ErrorMessage = "手机号不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string Mobil { get; set; }
[DisplayName("电子邮件")]
[Required(ErrorMessage = "电子邮件不得为空")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string Email { get; set; }
}
然后是BLL中的代码，Resposity 模式我暂时没用
public class UsersServices
{
DanaZhangMvcCmsContext _db = new DanaZhangMvcCmsContext();
public IQueryable<Users> Get()
{
var model = _db.Users.OrderBy(a => a.Id);
return model;
}
public Users Get(int Id)
{
var item = new Users();
item = _db.Users.SingleOrDefault(a => a.Id.Equals(Id));
return item;
}
public Users Get(string name)
{
var item = new Users();
item= _db.Users.SingleOrDefault(a => a.Name.Equals(name));
return item;
}
public string GetName(int Id)
{
string name = "您好，游客";
var user = Get(Id);
if (user != null)
name = user.Name;
return name;
}
public bool CheckUser(int Id, string password)
{
password = Common.DESEncrypt.Encrypt(password);
return Get(Id).Password.Equals( password);
}
public bool IsDuplicate(string name)
{
bool isDuplicate = false;
var item = _db.Users.SingleOrDefault(a => a.Name == name);
if (item != null)
isDuplicate = true;
return isDuplicate;
}
public bool IsDuplicateButSelf(int Id, string name)
{
bool isDuplicate = false;
var item = _db.Users.SingleOrDefault(a => a.Id != Id && a.Name == name);
if (item != null)
isDuplicate = true;
return isDuplicate;
}
public void Save(int Id, ref Users item)
{
_db.Users.Add(item);
_db.SaveChanges();
}
public void DeleteObject(int Id)
{
_db.Users.Remove(_db.Users.Single(a => a.Id == Id));
_db.SaveChanges();
}
}
在写Controller中的内容
public class AccountController : Controller { // // GET: /Account/ UsersServices _UsersBLL = new UsersServices(); public ActionResult LogOn() { return View(); } [HttpPost] public ActionResult LogOn(LogOnModel item) { bool isPower = true; string ip = Request.UserHostAddress; if (!ModelState.IsValid) { return View(item); } var item1 = _UsersBLL.Get(item.Name); if (item1 != null) { if (_UsersBLL.CheckUser(item1.Id, item.Password)) { FormsAuthentication.SetAuthCookie(item1.Name.ToString(),false); if (isPower) { return Redirect("/Admin"); } else { if (Request["ReturnUrl"] != null) { return Redirect(Request["ReturnUrl"]); } else { return Redirect("/"); } } } else { ModelState.AddModelError("", "用户名不存在或密码错误！"); } } else { ModelState.AddModelError("", "用户名不存在或密码错误！"); } return View(item); } public virtual ActionResult LogOff() { FormsAuthentication.SignOut(); return Redirect("/"); } #region 生成验证码图片 [OutputCache(Location = OutputCacheLocation.None, Duration = 0, NoStore = false)] public ActionResult SecurityCode() { string oldcode = TempData["SecurityCode"] as string; string code = CreateRandomCode(5); TempData["SecurityCode"] = code; return File(CreateValidateGraphic(code), "image/Jpeg"); } private byte[] CreateImage(string checkCode) { int iwidth = (int)(checkCode.Length * 12); System.Drawing.Bitmap image = new System.Drawing.Bitmap(iwidth, 20); Graphics g = Graphics.FromImage(image); Font f = new System.Drawing.Font("Arial", 10, System.Drawing.FontStyle.Bold); Brush b = new System.Drawing.SolidBrush(Color.White); g.Clear(Color.Blue); g.DrawString(checkCode, f, b, 3, 3); Pen blackPen = new Pen(Color.Black, 0); Random rand = new Random(); for (int i = 0; i < 5; i++) { int x1 = rand.Next(image.Width); int x2 = rand.Next(image.Width); int y1 = rand.Next(image.Height); int y2 = rand.Next(image.Height); g.DrawLine(new Pen(Color.Silver, 1), x1, y1, x2, y2); } System.IO.MemoryStream ms = new System.IO.MemoryStream(); image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); return ms.ToArray(); } private string CreateRandomCode(int codeCount) { string allChar = "0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,W,X,Y,Z"; string[] allCharArray = allChar.Split(','); string randomCode = ""; int temp = -1; Random rand = new Random(); for (int i = 0; i < codeCount; i++) { if (temp != -1) { rand = new Random(i * temp * ((int)DateTime.Now.Ticks)); } int t = rand.Next(35); if (temp == t) { return CreateRandomCode(codeCount); } temp = t; randomCode += allCharArray[t]; } return randomCode; } /// <summary> /// 创建验证码的图片 /// </summary> public byte[] CreateValidateGraphic(string validateCode) { Bitmap image = new Bitmap((int)Math.Ceiling(validateCode.Length * 16.0), 27); Graphics g = Graphics.FromImage(image); try { //生成随机生成器 Random random = new Random(); //清空图片背景色 g.Clear(Color.White); //画图片的干扰线 for (int i = 0; i < 25; i++) { int x1 = random.Next(image.Width); int x2 = random.Next(image.Width); int y1 = random.Next(image.Height); int y2 = random.Next(image.Height); g.DrawLine(new Pen(Color.Silver), x1, y1, x2, y2); } Font font = new Font("Arial", 13, (FontStyle.Bold | FontStyle.Italic)); LinearGradientBrush brush = new LinearGradientBrush(new Rectangle(0, 0, image.Width, image.Height), Color.Blue, Color.DarkRed, 1.2f, true); g.DrawString(validateCode, font, brush, 3, 2); //画图片的前景干扰点 for (int i = 0; i < 100; i++) { int x = random.Next(image.Width); int y = random.Next(image.Height); image.SetPixel(x, y, Color.FromArgb(random.Next())); } //画图片的边框线 g.DrawRectangle(new Pen(Color.Silver), 0, 0, image.Width - 1, image.Height - 1); //保存图片数据 MemoryStream stream = new MemoryStream(); image.Save(stream, ImageFormat.Jpeg); //输出图片流 return stream.ToArray(); } finally { g.Dispose(); image.Dispose(); } } #endregion }
然后就是View了
@model DanaZhangMvcCms.Model.LogOnModel
@{
Layout = null;
}

登录现在就算完成了，看一下我们的界面
