`safeURL` declares the provided string as a "safe" URL or URL substring (see [RFC 3986][]). A URL like `javascript:checkThatFormNotEditedBeforeLeavingPage()` from a trusted source should go in the page, but by default dynamic `javascript:` URLs are filtered out since they are a frequently exploited injection vector.
|
|
|
|
Without `safeURL`, only the URI schemes `http:`, `https:` and `mailto:` are considered safe by Go templates. If any other URI schemes (e.g., `irc:` and `javascript:`) are detected, the whole URL will be replaced with `#ZgotmplZ`. This is to "defang" any potential attack in the URL by rendering it useless.
|
|
|
|
The following examples use a [site `config.toml`][configuration] with the following [menu entry][menus]:
|
|
|
|
{{< code file="config.toml" copy="false" >}}
|
|
[[menu.main]]
|
|
name = "IRC: #golang at freenode"
|
|
url = "irc://irc.freenode.net/#golang"
|
|
{{< /code >}}
|
|
|
|
The following is an example of a sidebar partial that may be used in conjunction with the preceding front matter example:
|
|
|
|
{{< code file="layouts/partials/bad-url-sidebar-menu.html" copy="false" >}}
|
|
<!-- This unordered list may be part of a sidebar menu -->
|
|
<ul>
|
|
{{ range .Site.Menus.main }}
|
|
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
|
|
{{ end }}
|
|
</ul>
|
|
{{< /code >}}
|
|
|
|
This partial would produce the following HTML output:
|
|
|
|
{{< output file="bad-url-sidebar-menu-output.html" >}}
|
|
<!-- This unordered list may be part of a sidebar menu -->
|
|
<ul>
|
|
<li><a href="#ZgotmplZ">IRC: #golang at freenode</a></li>
|
|
</ul>
|
|
{{< /output >}}
|
|
|
|
The odd output can be remedied by adding ` | safeURL` to our `.URL` page variable:
|
|
|
|
{{< code file="layouts/partials/correct-url-sidebar-menu.html" copy="false" >}}
|
|
<!-- This unordered list may be part of a sidebar menu -->
|
|
<ul>
|
|
<li><a href="{{ .URL | safeURL }}">{{ .Name }}</a></li>
|
|
</ul>
|
|
{{< /code >}}
|
|
|
|
With the `.URL` page variable piped through `safeURL`, we get the desired output:
|
|
|
|
{{< output file="correct-url-sidebar-menu-output.html" >}}
|
|
<ul class="sidebar-menu">
|
|
<li><a href="irc://irc.freenode.net/#golang">IRC: #golang at freenode</a></li>
|
|
</ul>
|
|
{{< /output >}}
