RTCPeerConnection.getConfiguration()

The RTCPeerConnection.getConfiguration() method returns a RTCConfiguration object which indicates the current configuration of the RTCPeerConnection on which the method is called.

The configuration includes a list of the ICE servers used by the connection, information about transport policies, and identity information.

Syntax

configuration = RTCPeerConnection.getConfiguration();

Parameters

This method takes no input parameters.

Return value

An RTCConfiguration object describing the RTCPeerConnection's current configuration.

Example

This example adds a new certificate to an active connection if it doesn't already have one in use.

let configuration = myPeerConnection.getConfiguration();

if ((configuration.certificates != undefined) && (!configuration.certificates.length)) {
   RTCPeerConnection.generateCertificate({
      name: 'RSASSA-PKCS1-v1_5',
      hash: 'SHA-256',
      modulusLength: 2048,
      publicExponent: new Uint8Array([1, 0, 1])
  }).then(function(cert) {
    configuration.certificates = [cert];
    myPeerConnection.setConfiguration(configuration);
  });
}

This example fetches the current configuration of the RTCPeerConnection, then looks to see if it has any certificates set by examining whether or not (a) the configuration has a value for certificates, and (b) whether its length is zero.

If it's determined that there are no certificates in place, RTCPeerConnection.generateCertificate() is called to create a new certificate; we provide a fulfillment handler which adds a new array containing the one newly-created certificate to the current configuration and passes it to setConfiguration() to add the certificate to the connection.
