定义模型
type Person struct {
Name string `json:"name"`
Age int `json:"age"`
Birthday1 Carbon `json:"birthday1"`
Birthday2 Carbon `json:"birthday2" carbon:"date" tz:"PRC"`
Birthday3 Carbon `json:"birthday3" carbon:"time" tz:"PRC"`
Birthday4 Carbon `json:"birthday4" carbon:"dateTime" tz:"PRC"`
Birthday5 Carbon `json:"birthday5" carbon:"timestamp" tz:"PRC"`
Birthday6 Carbon `json:"birthday6" carbon:"timestampMilli" tz:"PRC"`
Birthday7 Carbon `json:"birthday7" carbon:"timestampMicro" tz:"PRC"`
Birthday8 Carbon `json:"birthday8" carbon:"timestampNano" tz:"PRC"`
}
或
type Person struct {
Name string `json:"name"`
Age int `json:"age"`
Birthday1 Carbon `json:"birthday1"`
Birthday2 Carbon `json:"birthday2" carbon:"layout:2006-01-02" tz:"PRC"`

实例化模型
now := Parse("2020-08-05 13:14:15", PRC)
person := Person {
Name: "gouguoyin",
Age: 18,
Birthday1: now,
Birthday2: now,
Birthday3: now,
Birthday4: now,
Birthday5: now,
Birthday6: now,
Birthday7: now,
Birthday8: now,
}
Json 编码
loadErr := carbon.LoadTag(&person)
if loadErr != nil {
// 错误处理
log.Fatal(loadErr)
}
data, marshalErr := json.Marshal(person)
if marshalErr != nil {
// 错误处理
log.Fatal(marshalErr)
}
fmt.Printf("%s", data)
// 输出
{
"name": "gouguoyin",
"age": 18,
"birthday1": "2020-08-05 13:14:15",
"birthday2": "2020-08-05",
"birthday3": "13:14:15",
"birthday4": "2020-08-05 13:14:15",
"birthday5": 1596604455,
"birthday6": 1596604455999,
"birthday7": 1596604455999999,
"birthday8": 1596604455999999999
}
Json 解码
str := `{
"name": "gouguoyin",
"age": 18,

}`

}
unmarshalErr := json.Unmarshal([]byte(str), &person)

}
fmt.Sprintf("%s", person.Birthday1) // 2002-08-05 13:14:15
