Connect with server using address instead of hostname+port number

[IrisG33]

Hi grpc-swift team,

The ClientConnection has to be initialized with hostname and port. But often the server should be accessed through a fully qualified domain name(FQDN) from clients, and it's not necessarily easy for clients to know the port number that the server is listening to. Wondering can gRPC-swift support to connect with server using the FQDN?

The FQDN generally does not encode the port. How are you expecting to find it out?

[IrisG33]

Apologize for using FQDN which is probably not I really meant. I'm more wondering can gRPC swift support to create the ClientConnection using API endpoint.
For example, the Google Cloud gRPC service can be configured as this example. The service has the endpoint name calendar.googleapis.com, and clients can send requests using the endpoint. I think this is supported in cgrpc .

I'm pretty confident that the port is simply defaulted to 443 in this case.

[IrisG33]

Yeah, tried with 443, and it works.

[Lukasa]

So, yes, we could absolutely provide an alternative constructor that just defaults the port to 443.

That would be nice :)
