我试图从一个pdf文件重定向到另一个。所以,例如:
https://my-site.com/the-first-file.pdf
应该重定向到
https://my-site.com/the-second-file.pdf
我在重定向上查看github's documentation,但我无法将该元数据添加到pdf文件...
任何帮助表示赞赏!

另一种(稍微好一点的IMO)方法是模仿jekyll-redirect
做什么,使用meta http-equiv="refresh"
标记要求浏览器重定向用户,这不需要javascript
即。您将删除the-first-file.pdf
并创建一个名为the-first-file.pdf.html
的文件,其中包含以下内容:
<!DOCTYPE html>
<meta charset="utf-8">
<title>Redirecting...</title>
<link rel="canonical" href="https://my-site.com/the-second-file.pdf">
<meta http-equiv="refresh" content="0; url=https://my-site.com/the-second-file.pdf">
<h1>Redirecting...</h1>
<a href="https://my-site.com/the-second-file.pdf">Click here if you are not redirected.</a>
<script>location="https://my-site.com/the-second-file.pdf"</script>
更好的是,您可以利用Jekyll生成此文件,并使用站点变量根据配置设置构建URL(当然,您也可以在javascript版本中执行此操作):

<!DOCTYPE html>
<meta charset="utf-8">
<title>Redirecting...</title>
{% assign redirect_url = "/the-second-file.pdf" | prepend: site.baseurl | prepend: site.url %}
<link rel="canonical" href="{{ redirect_url }}">
<meta http-equiv="refresh" content="0; url={{ redirect_url }}">
<h1>Redirecting...</h1>
<a href="{{ redirect_url }}">Click here if you are not redirected.</a>
<script>location="{{ redirect_url }}"</script>

var rp = require('request-promise'),
cheerio = require('cheerio'),
url = require('url'),
base = 'http://www.google.com';
var options = {
uri: base,
method: 'GET',
resolveWithFullResponse: true
};
rp(options)
.then (function (response) {
$ = cheerio.load(response.body);
var relativeLinks = $("img");
relativeLinks.each( function() {
var link = $(this).attr('src');
var fullImagePath = url.resolve(base, link); // should be absolute
console.log(link);
if (link.startsWith('http')){
console.log('abs');
}
else {
console.log('rel');
}
});
});
