RESTCONF HTTP Request Access

This is useful for custom authorization or general need to access the HTTP request information

Steps. 1.) Register a request restconf.RequestFilter with RESTCONF restconf.Server instance 2.) Filter returns a context.Context that contains any custom data that you might extract from the HTTP request like HTTP header information, URL parameters or certificate information. 3.) Values from that context.Context will be made available to all your node.Node implementations

s := restconf.NewServer(d)
s.Filters = append(s.Filters, filter)

func filter(ctx context.Context, w http.ResponseWriter, r *http.Request) (context.Context, error) {
    return context.WithValue(ctx, "mykey", "my-value"), nil
}

func myNode() node.Node {
    return nodeutil.Basic{
        OnAction: func(r node.ActionRequest) (node.Node, error) {
            myval := r.Selection.Context.Value("mykey")
        }
    }
}
