如何设置链接的到期时间？ [英] How to set Expiration time to the link?

问题描述

在我的asp.net项目中，在ForgotPassword页面中，我向用户emailid发送一个具有唯一ID的链接，并且我在sql server中的忘记密码表中插入电子邮件，uid，time，该链接将用户重置为重置密码页面。现在我想设置该链接的到期时间意味着我希望该链接在1天内过期。我怎么能这样做？

解决方案

你还没有为我提供任何代码，看看你怎么试过但仍然是

试试这个



< pre lang =c＃>



DateTime dtCreate = [从DB获取日期] ;

DateTime dtNow = DateTime.Now;

DateTime dtExp = dtCreate.AddDays（1）;

if（dtNow> dtExp）

{

Response.Write（页面已过期!!!!）;

}





< / pre>

这是我的代码：





公共部分类ForgotPassword：System.Web.UI.Page

{

SqlConnection con = new SqlConnection（ConfigurationManager.ConnectionStrings [conn ] .ToString（））;

SqlDataAdapter da，da1;

SqlCommand cmd;

DataSet ds，ds1;

Guid g = Guid.NewGuid（）;

protected void Page_Load（object sender，EventArgs e）

{



}

protected void btnSubmit_Click（object sender，EventArgs e）

{

string guid = g.ToString（）;

DateTime d = DateTime.Now;

//Response.Write（d.ToString（ ））;



string s =插入tblForgotPassword（电子邮件，ActivationCode，TimeDuration，Status）值（'+ txtemail.Text +'，'+ guid + '，'+ d.ToString（）+'，'待定'）;

da1 =新的SqlDataAdapter（s，con）;

ds1 = new DataSet（）;

da1.Fill（ds1）;



试试

{

DataSet ds = new DataSet（）;



{

con.Open（）;

SqlCommand cmd = new SqlCommand（SELECT RegId，UserName，Password FROM tblRegistration Where Email ='+ txtemail.Text.Trim（）+'，con）;

SqlDataAdapter da = new SqlDataAdapter（cmd）;

da.Fill（ds）;

con.Close（）;

Session [email ] = txtemail.Text;

}







if（b） ds.Tables [0] .Rows.Count> 0）

{

会话[用户名] = ds.Tables [0] .Rows [0] [UserName];

Session [RegId] = ds.Tables [0] .Rows [0] [RegId];

MailMessage Msg = new MailMessage（）;

/ /发件人电子邮件地址。

Msg.From =新邮件地址（txtemail.Text）;

//收件人电子邮件地址。

Msg.To.Add（txtemail.Text）;

Msg.Subject =您的密码详情;

//Msg.Body =
请检查您的登录详细信息

您的用户名：+ ds.Tables [0] .Rows [0] [UserName] +

您的密码：+ ds.Tables [0 ] .Rows [0] [密码] +

;



string Body =这封邮件是为了更改你的密码+

更改密码请点击下方
;

Body + =http：// loc alhost：1354 / socialnetworksite / ResetPassword.aspx？uid =+ g.ToString（）;



Msg.Body = Body;



Msg.IsBodyHtml = true;

//您的远程SMTP服务器IP。

SmtpClient smtp = new SmtpClient（）;

smtp.Host =smtp.gmail.com;

smtp.Port = 587;

smtp.Credentials = new System.Net.NetworkCredential（ [e-mail]，abc）;

smtp.EnableSsl = true;

smtp.Send（Msg）;

/ / Msg = null;

lbltxt.Text =您的密码详细信息发送到您的邮箱;

//清除文本框值

txtemail .Text =;

}

其他

{

lbltxt.Text =您输入的电子邮件不存在。;

}

}

catch（例外情况）

{

Console.WriteLine（{0}捕获异常。，ex）;

}

}

公共字符串Encryptdata（字符串密码）

{

string strmsg = string.Empty;

byte [] encode = new byte [password.Length];

encode = Encoding.UTF8。 GetBytes（密码）;

strmsg = Convert.ToBase64String（encode）;

返回strmsg;

}

}

In my asp.net project, in ForgotPassword page I am sending a link with unique id to the users emailid and also i am inserting email, uid, time in a forgotpassword table in sql server and that link refers users to a reset password page. Now I want to set expiration time of that link means I want that link will be expired in 1 day. How can I do that?

解决方案

You have not provided any code for me to see how you have tried but still
Try this

<pre lang="c#">

DateTime dtCreate= [Get Date from DB];
DateTime dtNow = DateTime.Now;
DateTime dtExp = dtCreate.AddDays(1);
if(dtNow > dtExp)
{
Response.Write("Page has Expired!!!!");
}


</pre>

Here is my code:


public partial class ForgotPassword : System.Web.UI.Page
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ToString());
SqlDataAdapter da,da1;
SqlCommand cmd;
DataSet ds,ds1;
Guid g = Guid.NewGuid();
protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnSubmit_Click(object sender, EventArgs e)
{
string guid = g.ToString();
DateTime d = DateTime.Now;
//Response.Write(d.ToString());

string s = "insert into tblForgotPassword(Email, ActivationCode, TimeDuration,Status) values('"+txtemail.Text+"','"+guid+"','"+d.ToString()+"','Pending')";
da1 = new SqlDataAdapter(s,con);
ds1 = new DataSet();
da1.Fill(ds1);

try
{
DataSet ds = new DataSet();

{
con.Open();
SqlCommand cmd = new SqlCommand("SELECT RegId,UserName,Password FROM tblRegistration Where Email= '" + txtemail.Text.Trim() + "'", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
Session["email"] = txtemail.Text;
}



if (ds.Tables[0].Rows.Count > 0)
{
Session["username"] = ds.Tables[0].Rows[0]["UserName"];
Session["RegId"] = ds.Tables[0].Rows[0]["RegId"];
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = new MailAddress(txtemail.Text);
// Recipient e-mail address.
Msg.To.Add(txtemail.Text);
Msg.Subject = "Your Password Details";
//Msg.Body = "Hi,
Please check your Login Detailss

Your Username: " + ds.Tables[0].Rows[0]["UserName"] + "

Your Password: " + ds.Tables[0].Rows[0]["Password"] + "

";

string Body = "Hi, this mail is to change your password" +
"To Change your Password Please click below
";
Body += "http://localhost:1354/socialnetworksite/ResetPassword.aspx?uid=" + g.ToString();

Msg.Body = Body;

Msg.IsBodyHtml = true;
// your remote SMTP server IP.
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "abc");
smtp.EnableSsl = true;
smtp.Send(Msg);
//Msg = null;
lbltxt.Text = "Your Password Details Sent to your mail";
// Clear the textbox valuess
txtemail.Text = "";
}
else
{
lbltxt.Text = "The Email you entered not exists.";
}
}
catch (Exception ex)
{
Console.WriteLine("{0} Exception caught.", ex);
}
}
public string Encryptdata(string password)
{
string strmsg = string.Empty;
byte[] encode = new byte[password.Length];
encode = Encoding.UTF8.GetBytes(password);
strmsg = Convert.ToBase64String(encode);
return strmsg;
}
}
