Permissions-Policy: geolocation directive
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The HTTP Permissions-Policy header
geolocation directive controls whether the current document is allowed to
use the Geolocation Interface.
Specifically, where a defined policy blocks use of this feature, calls to
getCurrentPosition() and
watchPosition() will cause those functions'
callbacks to be invoked with a GeolocationPositionError code of
PERMISSION_DENIED.
By default, the Geolocation API can be used within top-level documents and their same-origin child frames. This directive allows or prevents cross-origin frames from accessing geolocation. This includes same-origin frames.
Syntax
Permissions-Policy: geolocation=<allowlist>;
<allowlist>-
A list of origins for which permission is granted to use the feature. See
Permissions-Policy> Syntax for more details.
Default policy
The default allowlist for geolocation is self.
Examples
>General example
SecureCorp Inc. wants to disable the Geolocation API within all browsing contexts
except for its own origin and those whose origin is https://example.com. It
can do so by delivering the following HTTP response header to define a Permissions Policy:
Permissions-Policy: geolocation=(self "https://example.com")
With an <iframe> element
FastCorp Inc. wants to disable geolocation for all cross-origin child
frames, except for a specific <iframe>. It can do so by delivering the following
HTTP response header to define a Permissions Policy:
Permissions-Policy: geolocation=(self)
Then include an allow attribute on the
<iframe> element:
<iframe src="https://other.com/map" allow="geolocation"></iframe>
Interestingly, allow attributes can selectively enable features in certain frames, and not in others,
even if those frames contain documents from the same origin.
