Problem with NetworkingService regarding different version

[AdamSharon]

Hi, I believe there is a problem with how the URL is created for the Networking Service - there is no way (I can see) to add the version to the URL, so the request always fails. for example - I use the in-package integration test "ListNetworkTest()" to try and get all of my networks. I get this: Flurl.Http.FlurlHttpException Request to http://<IP>:9696/networks failed with status code 404 (Not Found).

However, when I debug I can modify the URL that it gets (from the endpoint) to this: http://<IP>:9696/v2.0/networks and then the service is working and I can see the networks.

BTW, Compute service is working fine with no problems.

Is there a way to add the version to the request URL without changing the core code ? or is this a real bug\over-looked problem ?

Thanks.

Try this and let me know if it gets you unstuck. On my local openstack dev env, I always end up changing the service catalog to append /v2.0 to the Neutron endpoint to avoid this problem.

What this does is have the SDK retrieve and cache the service catalog, then use reflection to update the networking endpoint to add /v2.0. Then use the networking service as usual.

using System;
using System.Linq;
using net.openstack.Core.Domain;
using net.openstack.Core.Providers;
using OpenStack.Networking.v2;
using OpenStack.Synchronous;

namespace AppendVersionToNeutronEndpoint
{
    class Program
    {
        static void Main(string[] args)
        {
            // 1. Authenticate and fill the service catalog cache
            var region = "RegionOne";
            var identityUrl = "http://example.com:5000/v2";
            var user = new CloudIdentityWithProject
            {
                Username = "username",
                Password = "password",
                ProjectName = "project"
            };
            var identity = new OpenStackIdentityProvider(new Uri(identityUrl), user);
            var userAccess = identity.Authenticate();

            // 2. Update the cached networking endpoint
            var networkingEndpoint = userAccess.ServiceCatalog.Single(svc => svc.Type == "network")
                .Endpoints.Single(e => e.Region == "RegionOne");
            networkingEndpoint.GetType().GetProperty("PublicURL")
                .SetValue(networkingEndpoint, $"{networkingEndpoint.PublicURL}/v2.0");

            // 3. Access the networking service using the updated endpoint
            var networking = new NetworkingService(identity, "RegionOne");
            var networks = networking.ListNetworks();
            Console.WriteLine($"Found {networks.Count()} network(s)!");

            Console.ReadLine();
        }
    }
}

This is working great, thanks! I'll follow to see how this will be fixed. Thanks again for the quick response.
