Я хотел бы использовать wkhtmltopdf для распечатки содержимого моего файла html. Я выполнил шаг, чтобы сделать это на https://wkhtmltopdf.org/, но мне просто не удалось преобразовать его в pdf. Я здесь что-то не так делаю?
Я запускаю эту команду.
C:\Program Files\wkhtmltopdf\bin>wkhtmltopdf.exe> C:\Users\MyPc\Desktop\test.html C:\Users\MyPc\Desktop\new.pdf
А вот содержимое моего html файла, которое я скопировал из https://wkhtmltopdf.org/usage/wkhtmltopdf.txt
<!DOCTYPE html>
<html><head><script>
function subst() {
var vars = {};
var query_strings_from_url = document.location.search.substring(1).split('&');
for (var query_string in query_strings_from_url) {
if (query_strings_from_url.hasOwnProperty(query_string)) {
var temp_var = query_strings_from_url[query_string].split('=', 2);
vars[temp_var[0]] = decodeURI(temp_var[1]);
}
}
var css_selector_classes = ['page', 'frompage', 'topage', 'webpage', 'section', 'subsection', 'date', 'isodate', 'time', 'title', 'doctitle', 'sitepage', 'sitepages'];
for (var css_class in css_selector_classes) {
if (css_selector_classes.hasOwnProperty(css_class)) {
var element = document.getElementsByClassName(css_selector_classes[css_class]);
for (var j = 0; j < element.length; ++j) {
element[j].textContent = vars[css_selector_classes[css_class]];
}
}
}
}
</script></head><body style="border:0; margin: 0;" onload="subst()">
<table style="border-bottom: 1px solid black; width: 100%">
<tr>
<td class="section"></td>
<td style="text-align:right">
Page <span class="page"></span> of <span class="topage"></span>
</td>
</tr>
</table>
</body></html>
И это ошибка, которую я получаю, когда запускаю приведенную выше команду, она также очищает мой html файл до пустого.
You need to specify at least one input file, and exactly one output file
Use - for stdin or stdout
Name:
wkhtmltopdf 0.12.6 (with patched qt)
Synopsis:
wkhtmltopdf [GLOBAL OPTION]... [OBJECT]... <output file>
Document objects:
wkhtmltopdf is able to put several objects into the output file, an object is
either a single webpage, a cover webpage or a table of contents. The objects
are put into the output document in the order they are specified on the
command line, options can be specified on a per object basis or in the global
options area. Options from the Global Options section can only be placed in
the global options area.
A page objects puts the content of a single webpage into the output document.
(page)? <input url/file name> [PAGE OPTION]...
Options for the page object can be placed in the global options and the page
options areas. The applicable options can be found in the Page Options and
Headers And Footer Options sections.
A cover objects puts the content of a single webpage into the output document,
the page does not appear in the table of contents, and does not have headers
and footers.
cover <input url/file name> [PAGE OPTION]...
All options that can be specified for a page object can also be specified for
a cover.
A table of contents object inserts a table of contents into the output
document.
toc [TOC OPTION]...
All options that can be specified for a page object can also be specified for
a toc, further more the options from the TOC Options section can also be
applied. The table of contents is generated via XSLT which means that it can
be styled to look however you want it to look. To get an idea of how to do
this you can dump the default xslt document by supplying the
--dump-default-toc-xsl, and the outline it works on by supplying
--dump-outline, see the Outline Options section.
