取消编组并从 json 数组中获取第 n 项

Question

我想解组 JSON 并从人群中获取第二个名字"安德烈鲍里森科"，

杰森：

text = `{"people": [{"craft": "ISS", "name": "Sergey Rizhikov"}, {"craft": "ISS", "name": "Andrey Borisenko"}, {"craft": "ISS", "name": "Shane Kimbrough"}, {"craft": "ISS", "name": "Oleg Novitskiy"}, {"craft": "ISS", "name": "Thomas Pesquet"}, {"craft": "ISS", "name": "Peggy Whitson"}], "message": "success", "number": 6}`

到目前为止我的代码：

package main
import (
"fmt"
"encoding/json"
)

type people struct {
NAME string `json:"craft"`
}
func main() {
const text = `{"people": [{"craft": "ISS", "name": "Sergey Rizhikov"}, {"craft": "ISS", "name": "Andrey Borisenko"}, {"craft": "ISS", "name": "Shane Kimbrough"}, {"craft": "ISS", "name": "Oleg Novitskiy"}, {"craft": "ISS", "name": "Thomas Pesquet"}, {"craft": "ISS", "name": "Peggy Whitson"}], "message": "success", "number": 6}`
textBytes := []byte(text)
people1 := people{}
err := json.Unmarshal(textBytes, &people1)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(people1.NAME.[1])
}

Answer 1

你对json.Unmarshal和结构的赋值不利于你想做的事情。

你的结构应该看起来像这样：

type myStruct struct {
Peoples []struct {
Craft string `json:"craft"`
Name string `json:"name"`
} `json:"people"`
}

这将为您提供一系列人员(Peoples(

for _, eachOne := range peopleStruct.Peoples {
fmt.Println(eachOne.Name) //eachOne.Name == name of you guys
fmt.Println(eachOne.Craft) //eachOne.Craft == craft of you guys
}

对于安德烈：fmt.Println(peopleStruct.Peoples[1].Name)
