如何为JSON创建正确的结构

Question

how to parse json correctly I have the following json file

{
    "hello": {
        "title": "Golang",
        "story": [
            "Go lang story",
            "Channel story"
        ],
        "options": [
            {
                "text": "That story",
                "arc": "west"
            },
            {
                "text": "Gee",
                "arc": "east"
            }
        ]
    },
    "world": {
        "title": "Visiting",
        "story": [
            "Boo",
            "Doo",
            "Moo",
            "Qoo"
        ],
        "options": [
            {
                "text": "weird",
                "arc": "west"
            },
            {
                "text": "funny",
                "arc": "north"
            }
        ]
    }
}

I've created these structs for the inner part

type chapter struct{
    Title string `json:"title"`
    Story []string `json:"story"`
    Option []option `json:"options"`
}

type option struct {
    Text string `json:"text"`
    Arc string `json:"arc"`
}

but I don't know how to parse wrappers like "hello" and "world"

Answer 1

All you need to do structuring the root map.

{
    "hello":{},
    "world":{}
}

Here the hello and world is also inside a map. So you need to structure them too.

 var root map[string]chapter
 json.Unmarshal(JSONDATA,&root)
