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
