How to retrieve current list of xNF functions from A&AI
...
?
Send Get GET request to this endpoint
Example curl command you can use to retrieve inventory from any pod within the cluster in which AAI is deployed to.

curl 'https://aai:8443{serverRoot}/aai/v23/network/pnfs' |
The above command returns a list of all the pnfs
...
the pnfs.
Example of the data that is returned by the curl command.

Proof of Concept code:
The below is Proof Of Concept code and it is not production ready. With this code, we are able to retrieve list of network functions from A&AI.
...
To write production ready code, the following things will need to be done.1) User
- User Story to implement One way SSL communication needed to make Https calls.
...
- Currently the project is not set up to make HTTPS calls. For the POC the following code was added to workaround this issue.

final TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new ArrayList<X509Certificate>().toArray(new X509Certificate[0]);
}
public void checkClientTrusted(final X509Certificate[] certs, final String authType) {
}
public void checkServerTrusted(final X509Certificate[] certs, final String authType) {
}
}
};
final SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
final HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(final String hostname, final SSLSession session) {
return true;
}
