Key	Returns the unique key for the given resource, equivalent to its publishing path.			related returnType signatures methods/resource/Permalink methods/resource/RelPermalink methods/resource/Publish string RESOURCE.Key

By way of example, consider this site configuration:

{{< code-toggle file=hugo >}} baseURL = 'https://example.org/docs/' {{< /code-toggle >}}

And this template:

  {{ with resources.Get "images/a.jpg" }}
    {{ with resources.Copy "foo/bar/b.jpg" . }}
      {{ .Key }} → foo/bar/b.jpg

      {{ .Name }} → images/a.jpg
      {{ .Title }} → images/a.jpg

      {{ .RelPermalink }} → /docs/foo/bar/b.jpg
    {{ end }}
  {{ end }}

We used the resources.Copy function to change the publishing path. The Key method returns the updated path, but note that it is different than the value returned by RelPermalink. The RelPermalink value includes the subdirectory segment of the baseURL in the site configuration.

The Key method is useful if you need to get the resource's publishing path without publishing the resource. Unlike the Permalink, RelPermalink, or Publish methods, calling Key will not publish the resource.
