Go 语言的时间工具库。
帮助
在集成的过程中有遇到问题，欢迎加 QQ 群 564704807 讨论。
安装
$ go get github.com/smartwalle/time4go
开始
package main
import (
"fmt"
"github.com/smartwalle/time4go"
"time"
)
func main() {
var now = time4go.Now()
fmt.Println(now)
var d = time4go.Date(2018, time.May, 20, 13, 14, 0, 0, time.Local)
fmt.Println(d)
}
获取当前日期所在周的第一天和最后一天
var now = time4go.Now()
now.BeginningDateOfWeek()
now.EndDateOfWeek()
获取当前日期所在月的第一天和最后一天
var now = time4go.Now()
now.BeginningDateOfMonth()
now.EndDateOfMonth()
JSON
- 设置序列化成 JSON 字符串时的格式
time4go.JSONFormatter = time4go.DefaultFormatter{Layout: "2006-01-02 15:04:05"}
例子:
package main
import (
"encoding/json"
"fmt"
"github.com/smartwalle/time4go"
)
func main() {
time4go.JSONFormatter = time4go.DefaultFormatter{Layout: "2006-01-02 15:04:05"}
var s = &Schedule{}
s.Begin = time4go.Now()
s.End = s.Begin.AddDate(0, 1, 0)
sBytes, _ := json.Marshal(s)
fmt.Println(string(sBytes))
var ts = `{"begin":"2019-11-10 09:59:21","end":"2019-12-10 09:59:21"}`
var s2 *Schedule
json.Unmarshal([]byte(ts), &s2)
fmt.Println(s2.Begin, s2.End)
}
type Schedule struct {
Begin *time4go.Time `json:"begin"`
End *time4go.Time `json:"end"`
}
- 自定义 Formatter
当然你也可以自定义 Formatter，只需要实现以下接口即可：
type TimeFormatter interface {
Format(t time.Time) ([]byte, error)
Parse(data []byte) (time.Time, error)
}
比如：
type MyFormatter struct {
}
func (this MyFormatter) Format(t time.Time) ([]byte, error) {
...
}
func (this MyFormatter) Parse(data []byte) (time.Time, error) {
...
}
time4go.JSONFormatter = MyFormatter{}
支持 SQL 类数据库
db, err := sql.Open("mysql", "xxx")
if err != nil {
fmt.Println("连接数据库出错：", err)
return
}
defer db.Close()
db.Exec("INSERT INTO `user` (`name`, `age`, `created_on`) VALUES (?, ?, ?)", "test", 18, time4go.Now())
