不能使用“encoding/json”覆盖鹰（类型接口 {}）

Question

我有以下代码，我想遍历所有元素或访问一个元素，birds["eagle"["quote"][2]但我无法弄清楚

package main

import (

    "fmt"

    "encoding/json"

)

func main() {

    birdJson := `{"birds": {"pigeon": {"quotes": "love the pigeons"}, "eagle": {"quotes": ["bird of prey", "soar like an eagle", "eagle has no fear"]}}}`

    var result map[string]interface{}

    json.Unmarshal([]byte(birdJson), &result)

    birds := result["birds"].(map[string]interface{})

    fmt.Printf("%v\n",birds)

    eagle := birds["eagle"]

    for key, value := range eagle {

        fmt.Println(key, value.(string))

    }

}

Answer 1

有几个问题：eagle := birds["eagle"] //eagle is of type interface{}所以把它投到地图上：eagle := birds["eagle"].(map[string]interface{})现在你可以迭代它了：for key, value := range eagle {         for _, e := range value.([]interface{}){         fmt.Println(key, e.(string))        }    }值又是这里的接口。所以首先转换为 []interface{} 然后转换为字符串。这是完整的工作代码： https ://play.golang.org/p/Bdnwit1wBYh
