package main import ( "fmt" "log" "time" "github.com/bsm/redeo" "github.com/bsm/redeo/resp" ) func main() { srv := redeo.NewServer(&redeo.Config{}) // Add a command handler for a custom command "mycommand" srv.HandleFunc("mycommand", func(out *resp.RequestWriter, in *resp.Request) { // Do some work time.Sleep(1 * time.Second) // Write a zero-length response back to the client out.WriteZero() }) // Start the server if err := srv.ListenAndServe("localhost:9736"); err != nil { log.Fatal(err) } }In this example, we create a Redis server using Redeo, and add a custom command "mycommand". When "mycommand" is received, we sleep for one second to simulate some work being done, then send back a zero-length response using the `WriteZero` method. This package library is useful for creating Redis clients and servers in Go language.
