golang方法中receiver为指针与不为指针的区别详析

type test struct{
 name string
}

func (t test) TestValue() {

func (t *test) TestPointer() {

}

type test struct{
 name string
}

func (t test) TestValue() {
 fmt.Printf("%s\n",t.name)
}

func (t *test) TestPointer() {

 //这里发生了复制,不受后面修改的影响
 m := t.TestValue
 
 t.name = "Li"
 m1 := (*test).TestPointer
 //Li
 m1(&t) 
 
 //wang
