Dear EO Support,
I am researching a PDF Solution to convert SharePoint Online page to PDF
The SharePoint Online used HTTPS, and user need to login first. I don't how to let EO.PDF.HtmlToPDF work with "cookies" or any method to connect to SharePoint Online for getting data and converting to PDF
Code:
var url = "https://hphamsp.sharepoint.com/sites/campbell/SitePages/Home.aspx";
var UserName = "thuy@hphamSP.onmicrosoft.com";
var Password = "Password!";
// get cookie
var cookieContainer = new MsOnlineClaimsHelper(url, UserName, Password).getCookieContainer();
var cookies = cookieContainer.GetCookies(new Uri(url));
HtmlToPdf.Options.Cookies.Add(cookies);
HtmlToPdf.ConvertUrl(url, @"E:\PDF\EO.pdf");
Error Message:
EO.Pdf.HtmlToPdfException: Failed to convert Url 'https://hphamsp.sharepoint.com/sites/campbell/SitePages/Home.aspx'.(500:The server encountered an unexpected condition that prevented it from fulfilling the request. This is an error returned by the Web server, not by the HTML to PDF converter. Please try to visit the same Url with your browser to verify whether the Url is valid.)\r\n at EO.Pdf.Internal.dg.a(String A_0, Boolean A_1)\r\n at EO.Pdf.Internal.dg.b(HtmlToPdfOptions A_0, String A_1, Boolean A_2)\r\n at EO.Pdf.Internal.dg.a(bs A_0)\r\n at EO.Pdf.Internal.lo.c.a(Byte[] A_0)
Updated:
After trying "HtmlToPdf.Options.AdditionalHeaders" instead of "HtmlToPdf.Options.Cookies", the error is "more general"
// get cookie
var cookieContainer = new MsOnlineClaimsHelper(url, UserName, Password).getCookieContainer();
var cookies = cookieContainer.GetCookies(new Uri(url));
string cookie = string.Format("{0}={1}; {2}={3}",
cookies[0].Name, cookies[0].Value,
cookies[1].Name, cookies[1].Value
);

And one more important question: Did EO.PDF.HtmlToPDF work on IIS6 and Win2003?

Hi, EO.Pdf HTMLToPDF is for .NET, so it works fine on IIS6 and Windows 2003. As for the SharePoint login, you can try to use HtmlToPdfSession object and see if that works for you: http://www.essentialobjects.com/doc/4/htmltopdf/session.aspxThe 500 error code is returned by your server. So you must look into your server's log to find out why. As for the more generic version of the error message, you might want to look into your event log to see if you can find more information on that. But I would recommend you to look into the 500 error first. Thanks!

Hi eo_support, Thank for your feedback. I already tried "HtmlToPdfSession", but only the "Login Page" was rendered Code:
Code: C#
using (HtmlToPdfSession session = HtmlToPdfSession.Create())
{
//Load the log in page
session.LoadUrl("https://hphamsp.sharepoint.com/_forms/default.aspx?wa=wsignin1.0");
//Fill the user name and password field with a valid user name
//and password. Here "username" and "password" are the name of
//the two form fields for user to enter their user name and
//password
session.Fill("login", UserName);
session.Fill("passwd", Password);
//Submit the log in page. Here "login" the name of the submit
//button in the page. You can think this method as simulating
//a "click" on that button. This session is logged in after
//the Submit method returns
session.Submit("SI");
//Now we are logged in, load the "MyProfile.html" page, which
//can only be accessed after log in
session.LoadUrl("https://hphamsp.sharepoint.com/sites/campbell/SitePages/Home.aspx");
//Render this page as PDF
session.RenderAsPDF(@"E:\PDF\EO1.pdf");
}
Beside, SharePoint Online site was hosted on Microsoft server. So I can't "look into your server's log"

Hi,
We tried to open the page here. We get a blank page. If you can PM us a working Url and a valid test username/password, we can try to look into it from here. The feature is designed to allow you to log into any Web server that logs in through form variables and stores authentications information by cookie.
Thanks!

Hi,
The page url is still valid. Please try
URL:https://hphamsp.sharepoint.com/sites/campbell/SitePages/Home.aspx
You will be redirect to "SharePoint Online Login" page. Please use
Account:thuy@hphamSP.onmicrosoft.com
Password:Password!
("https://hphamsp.sharepoint.com/_forms/default.aspx?wa=wsignin1.0" is the correct "SharePoint Online Login" page)

Hi, We looked into this and it does not appear HtmlToPdfSession will work. The reason is HtmlToPdfSession simulate a form post but SharePoint login process is more complicated than a single form post. In order to a conversion, you will need to capture and duplicate the cookies. So your original method was correct, except that you need to add the cookies into HtmlToPdfOptions.Cookies collection. We tried to manually capture the cookies using a tool called Fiddler and then send the cookie to the server and it works. Our steps are like this (download and install Fiddler if you do not already have it): 1. User google Chrome to login to your site, make sure you check both "Remember me" and "Keep me signed in". This will create the authentication cookies; 2. Close Chrome browser; 2. Run Fiddler; 3. Open Chrome browser, access https://hphamsp.sharepoint.com/sites/campbell/SitePages/Home.aspx;Now go to the first request in Fidder, go to "Headers" section, you should see the following cookies being sent to the server: FedAuth=xxxxx rtFa=yyyyyy Copy the content of these two cookies and then write your code like this:
Code: C#
//Create the cookies. You will need to replace this code
//with your MsOnlineClaimsHelper
System.Net.Cookie cookie1 =
new System.Net.Cookie("FedAuth", "...contents_of_fedauth_cookie....");
System.Net.Cookie cookie2 =
new System.Net.Cookie("rtFa", "....content_of_rtFa_cookie....");
//Use HtmlToPdfOptions.Cookies to carry the cookies
HtmlToPdfOptions options = new HtmlToPdfOptions();
options.Cookies.Add(cookie1);
options.Cookies.Add(cookie2);
//Convert the page with the correct cookies
HtmlToPdf.ConvertUrl(your_url, pdfFileName, options);
Note the difference between our code and your code is that you use AdditionalHeaders but we use HtmlToPdfOptions.Cookies. Please let us know if this approach works for you. Thanks!

Hi EO support, Sorry for the late feedback. I tried your method but it didn't work either, with same error message

Hi,
We tested your code and it works fine for us. Make sure you are running the latest EO.Pdf. Other than that we do not know what else to tell you.
Thanks!
