Permissions-Policy: geolocation
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
http
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:
http
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:
http
Permissions-Policy: geolocation=(self)
Then include an allow attribute on the
<iframe> element:
html
<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.
