Login - Wkhtmltopdf Log In To Web App?
Jan 10, 2011Having a problem with wkhtmltopdf. I'm using it to take pdf snapshots of pages on a website that has a username/password page. When the .exe runs, I end up with a snapshot of the login page (running the exe from my own ASP.NET app).
Does anybody know how I would get wkhtmltopdf to log into the site so that it can access the page it needs to take a snapshot of?
wkhtmltopdf is installed in the program files directory on the server and is being called via:
public void HtmlToPdf(string website, string destinationFile)
{
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = "wkhtmltopdf.exe";
startInfo.Arguments = website + " " + destinationFile;
Process.Start(startInfo);
}
EDIT -------------
I couldn't get the --cookie-jar method to work (see comments), but I did find another way to programmatically log in with the username/password in the querystring.
I pass the username/pw as params in my querystring and try to access the page I want with wkhtml. When the membership provider kicks me out to the login page, I access the params (which are stored in the url as the returnUrl param) via code-behind and authenticate myself. A simple response.redirect, and bingo -- I've got my PDF snapshot.
// Check to see if an outside program is trying
// to log in by passing creds in the querystring.
if (Request.QueryString["username"] != null) &&
Request.QueryString["password"] != null))
{
string user = Request.QueryString["username"];
string pw = Request.QueryString["password"];
if (System.Web.Security.Membership.ValidateUser(user, pw))
{
// Create an authentication ticket for wkhtml session
System.Web.Security.FormsAuthentication.SetAuthCookie(user, false);
if (Request.QueryString["ReturnUrl"] != null)
{
Response.Redirect(Request.QueryString["ReturnUrl"]);
}
}
else
{
throw new Exception("You failed to log in.");
}
}
C# - How To Use Wkhtmltopdf In Page That Requires Users To Be Logged In
Mar 2, 2011I have created a simple ASP.Net page to create self printable tickets so non-technical people can change the text and layout of a ticket. Obviously the user has to be logged in to be able to print their tickets.
When providing the URL for wkhtmltopdf to convert, the tickets are not created because wkhtmltopdf does not have a session to prove the user is logged in.
Is it possible to pass the session to wkhtmltopdf in the URL, or is their a better solution?

View 2 RepliesC# - Pass Model Values As Javascript Function Parameters From Inside Mvc Html Helper Such A Html.Radio?
Jul 20, 2010I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>
C# - Cannot Pass A Input From Text Box To A Query String And Then Keep The String In This Box?
May 28, 2010I have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

Using JQuery $.ajax To Pass String Value?
Mar 12, 2010I'm using ASP.NET and attempting to call a method with a signature of
[WebMethod]
public static string GetInfo(string id){...}
using the following javascript:
var elementValue = $("#element").attr('id');
[code]...
And this is not working.If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails.Why is this happening, and how do I resolve it?On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.
