Golang JSON 解析难题：如何将一组字节数组解析成结构体？

package main

import (
    "fmt"

    jsoniter "github.com/json-iterator/go"
)

type car struct {
    other []byte `json:"other"`
}

func main() {
    j := []byte(`{"other": {"a":[1,2]}}`)
    json := jsoniter.configcompatiblewithstandardlibrary
    obj := car{}
    err := json.unmarshal(j, &obj)
    if err != nil {
        fmt.println(err.error())
    } else {
        fmt.println(obj)
    }
}

main.car.other: base64codec: invalid input, error found in #10 byte of ...|{"other": {"a":[1,2]|..., bigger context ...|{"other": {"a":[1,2]}}|...

package main

import (
    "fmt"

    jsoniter "github.com/json-iterator/go"
)

type other struct {
    A []int `json:"a,omitempty"`
}

// Car 车
type Car struct {
    Other other `json:"other,omitempty"`
}

func main() {
    j := []byte(`{"other": {"a":[1,2]}}`)
    json := jsoniter.ConfigCompatibleWithStandardLibrary
    obj := Car{}
    err := json.Unmarshal(j, &obj)
    if err != nil {
        fmt.Println(err.Error())
    } else {
        fmt.Printf("%+v\n", obj)
    }
}
