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"`     Birthday3 Carbon `json:"birthday3" carbon:"layout:15:04:05" tz:"PRC"`     Birthday4 Carbon `json:"birthday4" carbon:"layout:2006-01-02 15:04:05" 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:"format:Y-m-d" tz:"PRC"`     Birthday3 Carbon `json:"birthday3" carbon:"format:H:i:s" tz:"PRC"`     Birthday4 Carbon `json:"birthday4" carbon:"format:Y-m-d H:i:s" 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"` }

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,     "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 }` var person Person  loadErr := carbon.LoadTag(&person) if loadErr != nil {     // 错误处理     log.Fatal(loadErr) }  unmarshalErr := json.Unmarshal([]byte(str), &person) if unmarshalErr != nil {     // 错误处理     log.Fatal(unmarshalErr) }  fmt.Sprintf("%s", person.Birthday1) // 2002-08-05 13:14:15 fmt.Sprintf("%s", person.Birthday2) // 2020-08-05 fmt.Sprintf("%s", person.Birthday3) // 13:14:15 fmt.Sprintf("%s", person.Birthday4) // 2002-08-05 13:14:15  fmt.Sprintf("%d", person.Birthday5) // 1596604455 fmt.Sprintf("%d", person.Birthday6) // 1596604455999 fmt.Sprintf("%d", person.Birthday7) // 1596604455999999 fmt.Sprintf("%d", person.Birthday8) // 1596604455999999999
