在golang中的struct内部定义和访问映射字段？

Question

Suppose I have a struct named Test,

type Test struct {
    Value1 int `json:"value1"`
    Value2 int `json:"Value2"`
    People map[string]string `json:"Value3"`
    Timeupdate string `json:"Timeupdate"`
}

and people variable is a collection of key value pairs. How can I define and access people inside the struct?

var object = Test{Value1: arg1, Value2: arg2, People: args3, Timeupdate: time.Now().String()}

how can I define and access people inside this object?

Answer 1

You could initialize an empty map:

args3 := map[string]string{}

Or a map with values:

args3 := map[string]string{"jane": "Jane"}

You can assign values later directly:

args3["john"] = "john"

Or after initializing object:

var object = Test{Value1: arg1, Value2: arg2, People: args3, Timeupdate: time.Now().String()}
object.People["claire"] = "Claire"
