为什么当我们使用(*structObj)引用struct时，go似乎返回structObj的新副本，而不是返回原始structObj的相同地址？这可能是我的一些误解，所以我要求澄清.
package main
import (
"fmt"
)
type me struct {
color string
total int
}
func study() *me {
p := me{}
p.color = "tomato"
fmt.Printf("%p\n", &p.color)
return &p
}
func main() {
p := study()
fmt.Printf("&p.color = %p\n", &p.color)
obj := *p
fmt.Printf("&obj.color = %p\n", &obj.color)
fmt.Printf("obj = %+v\n", obj)
p.color = "purple"
fmt.Printf("p.color = %p\n", &p.color)
fmt.Printf("p = %+v\n", p)
fmt.Printf("obj = %+v\n", obj)
obj2 := *p
fmt.Printf("obj2 = %+v\n", obj2)
}
输出
0x10434120
&p.color = 0x10434120
&obj.color = 0x10434140 //different than &p.color!
obj = {color:tomato total:0}
p.color = 0x10434120
p = &{color:purple total:0}
obj = {color:tomato total:0}
obj2 = {color:purple total:0} // we get purple now when dereference again
