获取类型和值
- TypeOf
- ValueOf
- pair<Type,Value>
package main
import (
"fmt"
"reflect"
)
func main() {
var num int =10
fmt.Println("type:",reflect.TypeOf(num))
fmt.Println("value:",reflect.ValueOf(num))
}
type: int
value: 10
获取字段和方法
package main
import (
"fmt"
"reflect"
)
type User struct {
Name string
Age int
}
func (this User)Invoke() {
fmt.Println("user method called")
}
func main() {
var num int =10
// 获取基础类型
fmt.Println("type:",reflect.TypeOf(num))
fmt.Println("value:",reflect.ValueOf(num))
user :=User{
Name: "Alice",
Age: 19,
}
inputType := reflect.TypeOf(user)
inputValue := reflect.ValueOf(user)
// 遍历字段
for i:=0;i<inputType.NumField();i++ {
field := inputType.Field(i)
fmt.Println("field:",field.Name,"value:",inputValue.Field(i).Interface())
}
// 遍历方法
for i:=0;i<inputType.NumMethod();i++ {
method := inputType.Method(i)
fmt.Println("methodName:",method.Name)
}
}
type: int
value: 10
field: Name value: Alice
field: Age value: 19
methodName: Invoke
