Question

我的网站托管在here:以上但是当我登录时，地址栏中的网址会不断重复并且变得更长，如：this，如果您点击左侧菜单，那么您可以看到地址栏，URL越来越大。请在上面建议我为什么URL会变得这么大？

请找到以下网站凭证：用户名：int123 密码：123

以下是代码示例：

           protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            if (Request.QueryString["type"] == "logout")
            {
                Session.Clear();
                Response.Cookies.Clear();
                //FormsAuthentication.SignOut();
                Response.Redirect("http://103.252.236.33/plesk-site-preview/2wayglobal.com/103.252.236.33/login.aspx");
            }
        }
    }

    protected void btnLogin_Click(object sender, EventArgs e)
    {
        string username = string.Empty;
        string userid = string.Empty;
        string address = string.Empty;
        string company = string.Empty;

        if ((txtUsername.Value.Trim() == string.Empty || txtUsername.Value.Trim() == "Username") && (txtPassword.Value.Trim() == string.Empty || txtPassword.Value.Trim() == "Password"))
        {
            //divError.Visible = true;
            lblError.Text = "Please type the correct username and password";
            ResetFields();
        }
        else if (txtUsername.Value.Trim() == string.Empty || txtUsername.Value.Trim() == "Username")
        {
            //divError.Visible = true;
            lblError.Text = "User name is incorrect.";
            ResetFields();
        }
        else if (txtPassword.Value.Trim() == string.Empty || txtPassword.Value.Trim() == "Password")
        {
            //divError.Visible = true;
            lblError.Text = "Password is incorrect.";
            ResetFields();
        }
        else
        {
            DataTable dtuserLogin = db.GetLoginDetails(txtUsername.Value.Trim(), txtPassword.Value.Trim());
            try
            {
                if (dtuserLogin.Rows.Count > 0)
                {
                    userid = Convert.ToString(dtuserLogin.Rows[0]["srno"]).Trim();
                    username = Convert.ToString(dtuserLogin.Rows[0]["username"]).Trim();
                    company = Convert.ToString(dtuserLogin.Rows[0]["company"]).Trim();
                    address = Convert.ToString(dtuserLogin.Rows[0]["address"]).Trim();
                    //FormsAuthentication.SetAuthCookie(username + ";" + company + ";" + address, true);
                }
            }
            catch (Exception ex)
            {
                throw new Exception("Error in btnLogin_Click()" + ex.Message);
            }

            if (username == "admin")
            {
                Response.Redirect("http://103.252.236.33/plesk-site-preview/2wayglobal.com/103.252.236.33/Admin/Default.aspx", true);
            }
            else
            {
                Response.Redirect("http://103.252.236.33/plesk-site-preview/2wayglobal.com/103.252.236.33/User/Default.aspx", true);
            }
        }
    }

    private void ResetFields()
    {
        txtUsername.Value = "Username";
        txtPassword.Value = "Password";
    }

Answer 1

只是btn click事件结束时的代码会将您重定向到该URL：

        if (username == "admin")
        {
            Response.Redirect("http://103.252.236.33/plesk-site-preview/2wayglobal.com/103.252.236.33/Admin/Default.aspx", true);
        }
        else
        {
            Response.Redirect("http://103.252.236.33/plesk-site-preview/2wayglobal.com/103.252.236.33/User/Default.aspx", true);
        }

我看不到导致问题的代码，但是我打赌$ 1你正在调用Redirect并传递你认为的绝对URL，但实际上是一个相对URL。浏览器将重定向视为相对，只是添加到地址栏中已有的URL末尾的路径。它会一遍又一遍地执行此操作，直到URL溢出其缓冲区并且出现Bad Request错误。

而不是

Response.Redirect("AbsolutePath/PageName.aspx") //This is a relative URL!

你应该使用

Response.Redirect("~/AbsolutePath/PageName.aspx")

或

Response.Redirect("/AbsolutePath/PageName.aspx")

或

Response.Redirect("https://ServerName.com/AbsolutePath/PageName.aspx")

......取决于你想要完成的事情。

为什么网址会重复？
