Question

我用过：

https://mholt.github.io/json-to-go/

进行转换

{
    "id": 5533,
    "action": "/api/v1/private/subscribe",  
    "arguments": {
        "instrument": ["BTC-19DEC14"],
       "event": ["order_book", "trade", "user_order"]
    }
}

进入

type AutoGenerated struct {
    ID        int    `json:"id"`
    Action    string `json:"action"`
    Arguments struct {
        Instrument []string `json:"instrument"`
        Event      []string `json:"event"`
    } `json:"arguments"`
}

然后我尝试如下在Go代码中使用此代码：

package main

import (
    "flag"
    "os"
)

var addr = flag.String("addr", "www.deribit.com", "http service address")

func main() {

    type AutoGenerated struct {
        ID        int    `json:"id"`
        Action    string `json:"action"`
        Arguments struct {
            Instrument []string `json:"instrument"`
            Event      []string `json:"event"`
        } `json:"arguments"`
    }

    json := &AutoGenerated{
        ID:     42,
        Action: "/api/v1/public/getorderbook",
        Arguments: struct {
            Instrument: ["BTC-19DEC14"],
            Event:       ["order_book", "trade", "user_order"],
        },
    }

}

我在Arguments中遇到错误，即我的结构在结构中。

如何将JSON转换为可以在go中使用的变量？

示例是..

package main

import (
    "flag"
    "fmt"
)

var addr = flag.String("addr", "www.deribit.com", "http service address")

type Arguments struct {
    Instrument []string `json:"instrument"`
    Event      []string `json:"event"`
}

type AutoGenerated struct {
    ID       int       `json:"id"`
    Action   string    `json:"action"`
    Argument Arguments `json:"arguments"`
}

func main() {

    json := &AutoGenerated{
        ID:     42,
        Action: "/api/v1/public/getorderbook",
        Argument: Arguments{
            Instrument: []string{"BTC-19DEC14"},
            Event:      []string{"order_book", "trade", "user_order"},
        },
    }

    fmt.Println(json)
}

如何将嵌套的JSON转换为Go代码？
