很難解釋，但是我怎樣才能得到一個(gè)實(shí)現(xiàn)某個(gè)接口的東西的指針呢？考慮下面的代碼：package mainimport (    "fmt"    "unsafe")type Interface interface {    Example()}type StructThatImplementsInterface struct {}func (i *StructThatImplementsInterface) Example() {}type StructThatHasInterface struct {    i Interface}func main() {    sameInterface := &StructThatImplementsInterface{}    struct1 := StructThatHasInterface{i: sameInterface}    struct2 := StructThatHasInterface{i: sameInterface}    TheProblemIsHere(&struct1)    TheProblemIsHere(&struct2)}func TheProblemIsHere(s *StructThatHasInterface) {    fmt.Printf("Pointer by Printf: %p \n", s.i)    fmt.Printf("Pointer by Usafe: %v \n", unsafe.Pointer(&s.i))}https://play.golang.org/p/HoC5_BBeswA結(jié)果將是：Pointer by Printf: 0x40c138 Pointer by Usafe: 0x40c140 Pointer by Printf: 0x40c138 Pointer by Usafe: 0x40c148 請(qǐng)注意，Printf獲得相同的值（因?yàn)閮烧叨糞tructThatHasInterface使用相同的sameInterface）。但是，unsafe.Pointer()返回不同的值。如果可能的話，我怎樣才能得到與Printfwithout use相同的結(jié)果？fmtreflect
