假设您有一个脚注my_footer.html，它包含以下内容：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script>
function substitutePdfVariables() {
function getParameterByName(name) {
var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
function substitute(name) {
var value = getParameterByName(name);
var elements = document.getElementsByClassName(name);
for (var i = 0; elements && i < elements.length; i++) {
elements[i].textContent = value;
}
}
['username'/*, 'topage', 'page',.. etc and any variable you would want to replace */]
.forEach(function(param) {
substitute(param);
});
}
</script>
</head>
<body onload="substitutePdfVariables()">
<span class="username"></span>
</body>
</html>您可以将"username“替换为某个值：
wkhtmltopdf my_super_html.html --footer-html my_footer.html --replace "username" "Veaer"请注意，我使用javascript将命名变量替换为我的值。

来自@dpineda和@viniciux的混合解决方案。此解决方案不会破坏样式表
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script charset="utf-8">
// For WKHTMLTOPDF Substitutions
window.onload = function()
{
function substitute(key, value)
{
var elements = document.getElementsByClassName(key);
for (var i = 0; elements && i < elements.length; i++)
{
elements[i].textContent = value;
}
}
var url = window.location.href.replace(/#$/, ""); // Remove last # if exist
// default params
//['page', 'section','sitepage','title','subsection','frompage','subsubsection','isodate','topage','doctitle','sitepages','webpage','time','date'];
var params = (url.split("?")[1] || "").split("&");
for (var i = 0; i < params.length; i++)
{
var param = params[i].split("=");
var key = param[0];
var value = param[1] || '';
var regex = new RegExp('{' + key + '}', 'g');
substitute(key, value);
}
}
</script>
</head>
<body onload="substitutePdfVariables()">
<span class="username"></span>
</body>

我对@viniciux做了一些调整，它实际上是有效的，所以这是对footer.html的改进
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script charset="utf-8">
function replaceParams() {
var url = window.location.href
.replace(/#$/, ""); // Remove last # if exist
// default params
//['page', 'section','sitepage','title','subsection','frompage','subsubsection','isodate','topage','doctitle','sitepages','webpage','time','date'];
var params = (url.split("?")[1] || "").split("&");
for (var i = 0; i < params.length; i++) {
var param = params[i].split("=");
var key = param[0];
var value = param[1] || '';
var regex = new RegExp('{' + key + '}', 'g');
document.body.innerText = document.body.innerText.replace(regex, value);
}
}
</script>
</head>
<body onload="replaceParams()">
name: {username}
age: {age}
url: {url}
page {page}
</body>
</html>然后您可以添加多个参数来动态替换
wkhtmltopdf page.html --footer-html footer.html --replace "username" "Veaer" --replace "age" "20" --replace "url" "google.com"请注意，页面将是当前的pdf页面，默认情况下会包含在参数列表中
