如何监控主窗体
在项目中我们总是的关注当某个用户在登陆后,如果有相同的用户也登陆则会出错,有时session会不无故丢失,有时控制用户在有效的时间段内才能运行或者控制注销等操作时,我们可以把监控窗体和主窗体分开。监测窗体主要控制上述功能。
在登陆窗体进行时间的检测。没有有效的登陆时间则不允许登陆
public partial class Login : PageBase
{
private string user;
private string pwd;
private int uid;
protected void Redirect(string rawUrl)
{
InitWebConsoleContext();
if (!string.IsNullOrEmpty(rawUrl))
this.Response.Redirect(rawUrl);
else
Response.Redirect("~/Main.aspx?NMS=Local", true);
}
protected void Page_Load(object sender, EventArgs e)
{
SetFocus(UserName);
AppTitle.Text = "";
this.Title = System.Configuration.ConfigurationSettings.AppSettings["AppTitle"];
Dictionary<string, string> context = new Dictionary<string, string>( StringComparer.CurrentCultureIgnoreCase );
if (((ISSOAuthentication)Services.GetService(typeof(ISSOAuthentication))).Authenticate(this, context))
{
context.TryGetValue("user", out user );
context.TryGetValue("pwd",out pwd);
string uid_string;
if (context.TryGetValue("uid", out uid_string))
uid = int.Parse(uid_string);
Redirect(this.Request["ReturnUrl"]);
return;
}
}
protected void LoginButton_Click(object sender, EventArgs e)
{
user = this.UserName.Text;
pwd = this.Password.Text;
WebAuthentication auth = (WebAuthentication)Services.GetService(typeof(WebAuthentication));
try
{
uid = auth.SignIn(user, pwd);
if (uid >= 0)
{
if (IsLoginTime(user))
{
Redirect(this.Request["ReturnUrl"]);
}
else
{
this.lblError.Text = (string)this.GetLocalResourceObject("InvalidLoginTime");
}
}
else
{
this.FailureText.Visible = true;
this.FailureText.Text = (string)this.GetLocalResourceObject("InvalidUserOrPwd");
}
}
catch (Exception se)
{
this.lblError.Text = se.Message;
}
}
//确定时间是否在允许的范围
private bool IsLoginTime(string userName)
{
IRepository Repository = (IRepository)Services.GetService(typeof(IRepository));
IUserRestriction ur = Repository.GetUserRestriction(userName, "UserLoginTime");
DateTime timeNow = DateTime.Now;
if (ur != null)
{
string strRes = ur.Restriction;
if (strRes == "")
return true;
string[] strDate = strRes.Split(',');
foreach (string s in strDate)
{
string[] date = s.Split(new string[] { "---"},System.StringSplitOptions.RemoveEmptyEntries);
DateTime TimeOne = DateTime.Parse(date[0]);
DateTime TimeTwo = DateTime.Parse(date[1]);
if (timeNow >= TimeOne && timeNow <= TimeTwo)
{
return true;
}
}
return false;
}
return true;
}
建一个监测窗体（ main.aspx）
public partial class Main : System.Web.UI.Page
{
string nms;
protected void Page_Load(object sender, EventArgs e)
{
nms = Request["NMS"];
Nms.Value = Request["NMS"];
this.Title = System.Configuration.ConfigurationSettings.AppSettings["AppTitle"];
}
}
在脚本中写（main.js）
// JScript 文件
var win,win1
function onloadme()
{
document.cookie
window.name = "btnm4_startup";
//window.resizeTo( 500,450);
//window.moveTo( (window.screen.availWidth - 500 )/2, (window.screen.availHeight- 450)/2)
win = window.open("", "BtnmMainWindow_"+document.all.Nms.value, "status=no,toolbar=no,menubar=no");
win.moveTo(0,0)
win.resizeTo( window.screen.availWidth , window.screen.availHeight);
document.btim.submit();
if( document.getElementById("show_btsm").value )
{
win1 = window.open("", "BtsmMainWindow_"+document.all.Nms.value, "status=no,toolbar=no,menubar=no");
win1.moveTo(0,0)
win1.resizeTo( window.screen.availWidth , window.screen.availHeight);
document.btsm.submit();
}
checkState();
}
function checkState()
{
CheckState.CheckRunState(document.all.Nms.value,checkStateCallback,checkStateError);
}
function checkStateCallback(result)
{
try
{
if(result.IsKicked && !result.IsUnRegistered)
{
win.close();
alert(result.Message);
window.location.href('logout.aspx');
}
if(result.IsUnRegistered && !result.IsKicked)
{
win.close();
alert(result.Message);
window.location.href('logout.aspx');
}
if(result.IsKicked && result.IsUnRegistered)
{
win.close();
alert(result.Message);
window.location.href('logout.aspx');
}
if(result.IsValidLoginTime)
{
win.close();
alert(result.Message);
window.location.href('logout.aspx');
}
}
catch(ex)
{}
window.setTimeout("checkState()",10000);
}
function checkStateError(result)
{
window.setTimeout("checkState()",10000);
}
创建一个webservice('webState.asmx')
