JSON到结构的转换

Question

This is the struct I have:

type Resource struct {
    Name string `json:"name"`
    Ranges struct {
        Range []struct {
            Begin int `json:"begin"`
            End   int `json:"end"`
        } `json:"range"`
    } `json:"ranges,omitempty"`
    Role string `json:"role,omitempty"`
    Type string `json:"type"`
    Scalar Scalar `json:"scalar,omitempty"`
}

I don't know how to make fields in the JSON not null. For example, struct Range like that:

{
    "name": "cpus",
    "ranges": {
        "range": null
    },
    "type": "SCALAR",
    "scalar": {
        "value": 1
    }
}, {
    "name": "mem",
    "ranges": {
        "range": null
}

That changes struct is resolved my problem:

type Resource struct {
    Name   string  `json:"name"`
    Ranges *Ranges  `json:"ranges,omitempty"`
    Role   string  `json:"role,omitempty"`
    Type   string  `json:"type"`
    Scalar *Scalar `json:"scalar,omitempty"`
}
