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.

  1. func main() {
  2.     flag.Parse()
  4.     a := serverplugin.NewAliasPlugin()
  5.     a.Alias("a.b.c.d", "Times", "Arith", "Mul")
  6.     s := server.NewServer()
  7.     s.Plugins.Add(a)
  8.     s.RegisterName("Arith", new(example.Arith), "")
  9.     err := s.Serve("reuseport", *addr)
  10.     if err != nil {
  11.         panic(err)
  12.     }
  13. }

Client can use alias to call the service:

  1. func main() {
  2.     flag.Parse()
  4.     d := client.NewPeer2PeerDiscovery("tcp@"+*addr, "")
  6.     option := client.DefaultOption
  7.     option.ReadTimeout = 10 * time.Second
  9.     xclient := client.NewXClient("a.b.c.d", client.Failtry, client.RandomSelect, d, option)
  10.     defer xclient.Close()
  12.     args := &example.Args{
  13.         A: 10,
  14.         B: 20,
  15.     }
  17.     reply := &example.Reply{}
  18.     err := xclient.Call(context.Background(), "Times", args, reply)
  19.     if err != nil {
  20.         log.Fatalf("failed to call: %v", err)
  21.     }
  23.     log.Printf("%d * %d = %d", args.A, args.B, reply.C)
  25. }
