我是 golang 的新手，我遇到了這個(gè)問題。 package main import "fmt" func main() { Problem := map[string]interface{}{ "Alan": map[string]interface{}{ "Particulars": map[string]interface{}{ "Age": "28", }, }, "Sophia": map[string]interface{}{ "Particulars": map[string]interface{}{ "Age": "18", }, }, } Ages := []string{} for key, value := range Problem { fmt.Println(key) fmt.Println(value) Ages = value["Age"] }}我想用“年齡”的勇氣來做某事，我該怎么做？

interface{} 類型中的值可以是任何類型的值。使用類型斷言確保值類型在訪問之前對操作有效：
package main
import "fmt"
func main() {
Problem := map[string]interface{}{
"Alan": map[string]interface{}{
"Particulars": map[string]interface{}{
"Age": "28",
},
},
"Sophia": map[string]interface{}{
"Particulars": map[string]interface{}{
"Age": "18",
},
},
}
Ages := []string{}
for key, value := range Problem {
fmt.Println(key)
fmt.Println(value)
a, ok := value.(map[string]interface{})["Particulars"].(map[string]interface{})["Age"].(string)
if ok {
Ages = append(Ages, a)
}
}
fmt.Println(Ages)
}
