两张背景图
后台代码
/// <summary> /// 登录 /// </summary> [HttpPost] public ActionResult LoginMvc(op_users login) { string Verification = WebHelper.GetSession("session_verifycode"); if (Session["session_verifycode"].IsEmpty() || Verification != MD5PassWordProvider.CutMD5(login.VerificationCode.ToLower(), 16)) { login.ErrorMessage = "您输入的验证码不正确。"; return Content(new AjaxResult { type = ResultType.info, message = "您输入的验证码不正确" }.ToJson()); //return View(login); } if (login.password.Length > 16) { login.ErrorMessage = "您输入的密码不正确。"; return Content(new AjaxResult { type = ResultType.info, message = "您输入的密码不正确" }.ToJson()); } var user = _userbll.Login(login.username, login.password); if (user == null) { login.ErrorMessage = "您输入的用户名不存在或密码不正确。"; return Content(new AjaxResult { type = ResultType.info, message = "您输入的用户名不存在或密码不正确" }.ToJson()); } if (user.IsExpire) { login.ErrorMessage = "该用户已经禁用。"; return Content(new AjaxResult { type = ResultType.info, message = "该用户已经禁用" }.ToJson()); } WebHelper.WriteSession("session_FullName", user.FullName); WebHelper.WriteSession("session_UserId", user.id); return Content(new AjaxResult { type = ResultType.success, message = "登陆成功" }.ToJson()); }
整个登陆就OK
