Re: [go-nuts] How to use .toml file to parse IP address and port to http server
Hi,
I have applied similar scenario to the function below but am not getting
the Ip address and the port number. Below is the function
var addr string
func init(){
var conf Config
if _, err := toml.Decode("config.toml", ); err != nil {
// handle error
}
addr = net.JoinHostPort(conf.Addr, conf.Port)
fmt.Println(addr) // This printing empty
}
func main() {
server := NewServer()
go func() {
if err :=
server.ListenAndServeTLS("/home/cumucore/diam/server.crt",
"/home/cumucore/diam/server.key"); err != nil && err !=
http.ErrServerClosed {
logger.Fatalf("Could not listen on %s: %v\n", addr, err)
if err := server.ListenAndServe(); err != nil {
logger.Fatalf("Could not listen on %s: %v\n", addr, err)
}
}
}()
}
// Create a new server
func NewServer() *http.Server {
return {
Addr: addr,
Handler: diam.NewRouter(),
ErrorLog: logger,
ReadTimeout: 5 * time.Second,
WriteTimeout: 10 * time.Second,
IdleTimeout: 15 * time.Second,
}
}
Ther config.toml file contain the key values as
Addr = "192.168.9.186"
Port = "8000"
What might be the problem in this case

Re: [go-nuts] How to use .toml file to parse IP address and port to http server
Use net.JoinHostPort to concatenate the values you have in the struct
and pass the to http.Server struct.
if _, err := toml.Decode("config.toml", ); err != nil {
// handle error
}
addr, err := net.JoinHostPort(conf.Address, conf.PORT)
if err != nil {
// handle error
}
src := {
Addr: addr,
}
Be sure to set explicit struct tags on your destination struct that
will be used for unmarshalling the toml. This way the decoder will know
which struct fields to populate.
type Config struct {
PORTstring `toml:"port"`
Address string `toml:"address"`
}
This will only be necessary though if you want the fields to map
differently depending on their name.

[go-nuts] How to use .toml file to parse IP address and port to http server
Hi,
How I can use the .toml file to parse IP address and port to simple http
server instead of using flags
I have a config.toml file which contains these parameters in
PORT = "8000"
Address = "localhost"
//Parameters type struct as
type Config struct {
PORTstring
Address string
}
I can load file in main function as
var conf Config
if _, err := toml.Decode("config.toml", ); err != nil {
// handle error
}
//simple http server main function
func main() {
var dir string
flag.StringVar(, "dir", ".", "the directory to serve files from.
Defaults to the current dir")
flag.Parse()
r := mux.NewRouter()
// This will serve files under http://localhost:8000/static/
r.PathPrefix("/static/").Handler(http.StripPrefix("/static/",
http.FileServer(http.Dir(dir
srv := {
Handler: r,
Addr: "127.0.0.1:8000",
WriteTimeout: 15 * time.Second,
ReadTimeout: 15 * time.Second,
}
log.Fatal(srv.ListenAndServe())
}
Any help?
