概述 序列化：將Go資料轉化為json字串

定義結構體

type Person struct {
    Name    string
    Age     int
    Sex     bool
    Hobbies []string
}

定義資料

var (
    zhangqd, mutz Person
    ps            []Person
    mMap, yMap    map[string]interface{}
    mSlice        []map[string]interface{}
)

初始化資料

func init() {
    //初始化結構體資料
 

    zhangqd = Person{"張全蛋", 20, true, []string{"質檢", "維護流水線", "打飯"}}
    mutz = Person{"穆鐵花", 23, false, []string{"搞破壞", "維護流水線", "打人"}}
    ps = make([]Person, 0)
    ps = append(ps, zhangqd, mutz)

    //初始化map資料
    mMap = make(map[string]interface{})
    mMap["name"] = "張全蛋"
    mMap["age"] = 20
    mMap["sex"
 
] = true
    mMap["hobbies"] = []string{"質檢", "維護流水線", "打飯"}
    yMap = make(map[string]interface{})
    yMap["name"] = "穆鐵柱"
    yMap["age"] = 23
    yMap["sex"] = false
    yMap["hobbies"] = []string{"破壞", "維護流水線", "打人"}

    //初始化切片資料
    mSlice = make([]map[string]interface{}, 0)
    mSlice = append
 
(mSlice, mMap, yMap)
}

序列化結構體

func main11() {
    //bytes, err := json.Marshal(zhangqd)
    bytes, err := json.Marshal(ps)
    if err != nil {
        fmt.Println("序列化失敗,err=", err)
    } else {
        jsonStr := string(bytes)
        fmt.Println("序列化結果：", jsonStr)
    }
}

序列化map

func main12() {
    bytes, err := json.Marshal(mMap)
    if err != nil {
        fmt.Println("序列化失敗,err=", err)
    } else {
        jsonStr := string(bytes)
        fmt.Println("序列化結果：", jsonStr)
    }
}

序列化切片

func main13() {
    bytes, err := json.Marshal(mSlice)
    if err != nil {
        fmt.Println("序列化失敗,err=", err)
    } else {
        jsonStr := string(bytes)
        fmt.Println("序列化結果：", jsonStr)
    }
}
