For people migrating existing published content to Hugo, there's a good chance you need a mechanism to handle redirecting old URLs.
|
|
|
|
Luckily, redirects can be handled easily with _aliases_ in Hugo.
|
|
|
|
## Example
|
|
|
|
Given a post on your current Hugo site, with a path of:
|
|
|
|
``content/posts/my-awesome-blog-post.md``
|
|
|
|
... you create an "aliases" section in the frontmatter of your post, and add previous paths to that.
|
|
|
|
### TOML frontmatter
|
|
|
|
```toml
|
|
+++
|
|
...
|
|
aliases = [
|
|
"/posts/my-original-url/",
|
|
"/2010/01/01/even-earlier-url.html"
|
|
]
|
|
...
|
|
+++
|
|
```
|
|
|
|
### YAML frontmatter
|
|
|
|
```yaml
|
|
---
|
|
...
|
|
aliases:
|
|
- /posts/my-original-url/
|
|
- /2010/01/01/even-earlier-url.html
|
|
...
|
|
---
|
|
```
|
|
|
|
Now when you visit any of the locations specified in aliases, _assuming the same site domain_, you'll be redirected to the page they are specified on.
|
|
|
|
## Important Behaviors
|
|
|
|
1. *Hugo makes no assumptions about aliases. They also don't change based
|
|
on your UglyURLs setting. You need to provide absolute path to your webroot
|
|
and the complete filename or directory.*
|
|
|
|
2. *Aliases are rendered prior to any content and will be overwritten by
|
|
any content with the same location.*
|
|
|
|
## How Hugo Aliases Work
|
|
|
|
When aliases are specified, Hugo creates a physical folder structure to match the alias entry, and, an html file specifying the canonical URL for the page, and a redirect target.
|
|
|
|
Assuming a baseurl of `mysite.tld`, the contents of the html file will look something like:
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<link rel="canonical" href="http://mysite.tld/posts/my-original-url"/>
|
|
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
|
|
<meta http-equiv="refresh" content="0;url=http://mysite.tld/posts/my-original-url"/>
|
|
</head>
|
|
</html>
|
|
```
|
|
|
|
The `http-equiv="refresh"` line is what performs the redirect, in 0 seconds in this case.
