Problem with external URL links #521

Closed stephaned68 closed 3 months ago

stephaned68 commented 4 months ago

Hi Using htmldoc 1.8.27 on Ubuntu 16.04

We have a problem with hyperlinks linking to some external URLs ("https://www.website.com/some/path?with=argument&other=argument")

In the resulting PDF, the text for the links are underlined as expected but they do not open a browser to the specified internet address

Here is a series of tests I did with this simple file : 

<HTML>
<HEAD>
<TITLE>Test</TITLE>
</HEAD>
<BODY>
<A HREF="https://www.visserie-service.fr">Visserie Service</A>
</BODY>
</HTML>

The original command in our software is the following : 

htmldoc --webpage --no-embedfonts --size a4 --left 12mm --footer n/N --strict -t pdf /home/stephane/test.htmldoc >/home/stephane/test.htmldoc.pdf

It creates the PDF output with this sent to stderr and a non functional hyperlink

PAGES: 1
ERR015: Unable to resolve link to ""!
BYTES: 3207

I have tried to add the --links option, same stderr output and same PDF file with underlined link that sends nowhere I have tried without the --strict option, which removes the ERR015 but still produces a PDF with a non-functional hyperlink

Any idea what we are doing wrong ? Or is this something not supported with our old htmldoc version ?

TIA

Well, it should work with 1.8.27, but that release is over 10 years old...

Is it possible your version of HTMLDOC is compiled without HTTPS support? Running "ldd /usr/bin/htmldoc" will show whether it is linked against any crypto/ssl/tls libraries...

There are some ssl and crypto libs linked in

OK, well it has been compiled against OpenSSL so there is HTTPS support - maybe HTMLDOC just isn't able to negotiate a TLS connection?

You could try changing the link to "http:" and see if that is the case. Unfortunately, some web sites are blocking TLS/1.0 now and that's all you'd have with the OpenSSL on Ubuntu 16.04.

I have done all kinds of tests, with http:// instead of https:// and even without any http prefix Same result : a clickable link that goes nowhere on the Chromeboxes used at our company, and to the Windows directory where I have downloaded the PDF on my PC. Which probably indicates that the address/link in the PDF is just empty

Guess when we'll update Ubuntu, we'll also install a newer htmldoc
