RTCPeerConnection.peerIdentity
The read-only RTCPeerConnection
property peerIdentity
returns a JavaScript Promise
that resolves to an RTCIdentityAssertion
which contains a DOMString
identifying the remote peer. Once this promise resolves successfully, the resulting identity is the target peer identity and cannot change for the duration of the connection.
Syntax
var identity = rtcPeerConnection.peerIdentity;
Value
A JavaScript Promise
which resolves to an RTCIdentityAssertion
that describes the remote peer's identity.
If an error occcurs while attempting to validate an incoming identity assertion (that is, the information describing a peer's identity), the promise is rejected. If there isn't already a target peer identity, peerIdentity
is set to a newly created promise and the process begins again, until the process succeeds or no further attempts to authenticate occur.
Note: The promise returned by setRemoteDescription()
cannot resolve until any target peer identity that's been set is validated. If the identity hasn't been validated yet, the promise returned by setRemoteDescription()
will be rejected. If there's no target peer identity, setRemoteDescription()
doesn't need to wait for validation to occur before it resolves.
Example
In this example, a function, getIdentityAssertion()
, is created which asynchronously waits for the peer's identity to be verified, then returns the identity to the caller. If an error occurs and the promise is rejected, this logs the error to the console and returns null
to the caller.
let pc = new RTCPeerConnection(); /* ... */ async function getIdentityAssertion(pc) { try { const identity = await pc.peerIdentity; return identity; } catch(err) { console.log("Error identifying remote peer: ", err); return null; } }
