golang反射调用方法

package main

import (
    "fmt"
    "reflect"
)

type Person struct {
    Name string `json:"name" from:"name" msg:"名字必填"`
    Age  int    `json:"age" from:"age" msg:"年龄必填"`
}

func (this Person) GetName() string {
    return this.Name
}

func (this *Person) SetName(name string) {
    this.Name = name
}

func main() {
    p := Person{
        Name: "小明",
        Age:  20,
    }
    v := reflect.ValueOf(&p)
    var params []reflect.Value
    params = append(params, reflect.ValueOf("李四"))
    b := v.MethodByName("SetName").Call(params)
    fmt.Println(b)
    a := v.MethodByName("GetName").Call(nil)
    fmt.Println(a)
    fmt.Printf("%#v", p)
}

执行结果

[]
[李四]
main.Person{Name:"李四", Age:20}
