getTransports() is a method of the AuthenticatorAttestationResponse interface that returns an 数组 containing strings describing the different transports which may be used by the authenticator.

Such transports may be USB, NFC, BLE or internal (applicable when the authenticator is not removable from the device).

注意： An AuthenticatorAttestationResponse instance is available on PublicKeyCredential.response after calling navigator.credentials.create() .

注意： This method may only be used in top-level contexts and will not be available in an <iframe> 例如。

arrTransports = authenticatorAttestationResponse.getTransports()
					

参数

• "nfc" : the authenticator may be used over NFC (Near Field Communication)
• "ble" : the authenticator may be used over BLE (Bluetooth Low Energy)
• "internal" : the authenticator is specifically bound to the client device (cannot be removed).

范例

var publicKey = {
  challenge: /* from the server */,
  rp: {
    name: "Example CORP",
    id  : "login.example.com"
  },
  user: {
    id: new Uint8Array(16),
    name: "jdoe@example.com",
    displayName: "John Doe"
  },
  pubKeyCredParams: [
    {
      type: "public-key",
      alg: -7
    }
  ]
};
navigator.credentials.create({ publicKey })
  .then(function (newCredentialInfo) {
    var transports = newCredentialInfo.response.getTransports();
    console.table(transports); // may be something like ["internal", "nfc", "usb"]
  }).catch(function (err) {
     console.error(err);
