Alias

Example: alias

This plugin can alias a service and its method.

For example, the below code use a.b.c.d as the alias of Arith, and Times as the alias of Mul.

func main() {
    flag.Parse()

    a := serverplugin.NewAliasPlugin()
    a.Alias("a.b.c.d", "Times", "Arith", "Mul")
    s := server.NewServer()
    s.Plugins.Add(a)
    s.RegisterName("Arith", new(example.Arith), "")
    err := s.Serve("reuseport", *addr)
    if err != nil {
        panic(err)
    }
}

Client can use alias to call the service:

func main() {
    flag.Parse()

    d := client.NewPeer2PeerDiscovery("tcp@"+*addr, "")

    option := client.DefaultOption
    option.ReadTimeout = 10 * time.Second

    xclient := client.NewXClient("a.b.c.d", client.Failtry, client.RandomSelect, d, option)
    defer xclient.Close()

    args := &example.Args{
        A: 10,
        B: 20,
    }

    reply := &example.Reply{}
    err := xclient.Call(context.Background(), "Times", args, reply)
    if err != nil {
        log.Fatalf("failed to call: %v", err)
    }

    log.Printf("%d * %d = %d", args.A, args.B, reply.C)

}
