RTCPeerConnection.getConfiguration

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

The returned configuration is the last configuration applied via setConfiguration(), or if setConfiguration() hasn't been called, the configuration the RTCPeerConnection was constructed with. The configuration includes a list of the ICE servers used by the connection, information about transport policies, and identity information.

Syntax

var 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.
