在内部有一个切片的两个结构之间传递值

Question

我有 2 个结构，里面有一个切片，如下所示：type BookX struct {  SomeValue string  Book1 []Book1}type Book1 struct {  Name string  Author string}type BookY struct {  SomeValue string  Book2 []Book2}type Book2 struct {  Name string  Author string}我想将结构 BookX 中第一个切片中的值传递给 BookY 中的另一个切片。尝试过这种方式但不起作用：func someName(bookX BookX){  var bookY BookY  bookY.Book2 = append(bookY.Book2, bookX.Book1...)}

Answer 1

Book1即使他们有相同的成员，也是Book2不同的类型。您不能追加[]Book1到[]Book2.

Book2一种解决方案是从创建实例Book1并将它们添加到[]Book2.

func someName(bookX BookX){

  var bookY BookY

  for _, book1 := range bookx.Book1 {

    book2 := Book2 {

      Name: book1.Name,

      Author: book1.Author,

    }

    bookY.Book2 = append(bookY.Book2, book2)

  }

}
