Golang: format a string without printing?
How to find a type of a object in Golang?
package main
import (
"fmt"
"reflect"
)
func main() {
tst := "string"
tst2 := 10
tst3 := 1.2
fmt.Println(reflect.TypeOf(tst))
fmt.Println(reflect.TypeOf(tst2))
fmt.Println(reflect.TypeOf(tst3))
}
// 或者
func typeof(v interface{}) string {
return fmt.Sprintf("%T", v)
}
// 或者
func typeof(v interface{}) string {
return reflect.TypeOf(v).String()
}
// 或者
func typeof(v interface{}) string {
switch t := v.(type) {
case int:
return "int"
case float64:
return "float64"
//... etc
default:
_ = t
return "unknown"
}
}
