GO Date数据处理
今天封装了一个go 的date数据处理,方便以后直接用
1、创建dateformat.go文件
package model
import (
"fmt"
"time"
)
type dateFormatter struct {
time.Time
}
// ConvertTimeStringToTimestamp 将指定格式的时间字符串转换为 Unix 时间戳
func (u *dateFormatter) ConvertTimeStringToTimestamp(timeString, layout string) (int64, error) {
t, err := time.Parse(layout, timeString)
if err != nil {
return 0, err
}
return t.Unix(), nil
}
// ConvertTimeStringFormat 将时间字符串从一种格式转换为另一种格式
func (u *dateFormatter) ConvertTimeStringFormat(timeString, originalLayout, newLayout string) (string, error) {
t, err := time.Parse(originalLayout, timeString)
if err != nil {
return "", err
}
return t.Format(newLayout), nil
}
// CalculateDateDifference 计算两个日期之间的天数差
func (u *dateFormatter) CalculateDateDifference(date1, date2, layout string) (int, error) {
d1, err := time.Parse(layout, date1)
if err != nil {
return 0, err
}
d2, err := time.Parse(layout, date2)
if err != nil {
return 0, err
}
duration := d2.Sub(d1)
return int(duration.Hours() / 24), nil
}
// AddDaysToDate 为指定日期增加或减少天数
func (u *dateFormatter) AddDaysToDate(date string, days int, layout string) (string, error) {
d, err := time.Parse(layout, date)
if err != nil {
return "", err
}
newDate := d.Add(time.Duration(days) * 24 * time.Hour)
return newDate.Format(layout), nil
}
// ConvertTimestampToTimeString 将 Unix 时间戳转换为指定格式的时间字符串
func (u *dateFormatter) ConvertTimestampToTimeString(timestamp int64, layout string) string {
t := time.Unix(timestamp, 0)
return t.Format(layout)
}
// CompareDates 比较两个日期,返回-1(日期1早于日期2),0(日期相等),1(日期1晚于日期2)
func (u *dateFormatter) CompareDates(date1, date2, layout string) (int, error) {
d1, err := time.Parse(layout, date1)
if err != nil {
return 0, err
}
d2, err := time.Parse(layout, date2)
if err != nil {
return 0, err
}
if d1.Before(d2) {
return -1, nil
}
if d1.After(d2) {
return 1, nil
}
return 0, nil
}
// ConvertTimeRange 解析并转换时间区间为指定格式或Unix时间戳
func (u *dateFormatter) ConvertTimeRange(startTimeStr, endTimeStr, layout, outputLayout string) (string, string, error) {
startTime, err := time.Parse(layout, startTimeStr)
if err != nil {
return "", "", err
}
endTime, err := time.Parse(layout, endTimeStr)
if err != nil {
return "", "", err
}
if outputLayout == "unix" {
// 返回Unix时间戳
startUnix := fmt.Sprintf("%d", startTime.Unix())
endUnix := fmt.Sprintf("%d", endTime.Unix())
return startUnix, endUnix, nil
} else {
// 返回指定格式的字符串
startFormatted := startTime.Format(outputLayout)
endFormatted := endTime.Format(outputLayout)
return startFormatted, endFormatted, nil
}
}
// ExtractDateComponents 从字符串日期中提取年、月、日、小时、分钟、秒等数据
func (u *dateFormatter) ExtractDateComponents(dateStr, layout string) (int, int, int, int, int, int, error) {
date, err := time.Parse(layout, dateStr)
if err != nil {
return 0, 0, 0, 0, 0, 0, err
}
year := date.Year()
month := int(date.Month())
day := date.Day()
hour := date.Hour()
minute := date.Minute()
second := date.Second()
return year, month, day, hour, minute, second, nil
}
// ConvertISOToCustomFormat 将ISO时间格式转换为指定的格式
func (u *dateFormatter) ConvertISOToCustomFormat(isoTimeStr, outputLayout string) (string, error) {
date, err := time.Parse(time.RFC3339, isoTimeStr)
if err != nil {
return "", err
}
return date.Format(outputLayout), nil
}
2、创建单元测试测试文件
dateformat_test.go
package model
import (
"fmt"
"testing"
)
func TestConvertISOWithTimezone(t *testing.T) {
isoTimeStr := "2024-08-30T14:00:00+02:00"
testData := dateFormatter{}
// 转换为自定义格式
customFormat, err := testData.ConvertISOToCustomFormat(isoTimeStr, "2006-01-02 15:04:05 MST")
if err != nil {
fmt.Println("Error converting ISO time:", err)
} else {
fmt.Println("Converted Time:", customFormat)
}
// 另一个转换例子:转换为UTC时间格式
customUTCFormat, err := testData.ConvertISOToCustomFormat(isoTimeStr, "2006-01-02 15:04:05 UTC")
if err != nil {
fmt.Println("Error converting ISO time:", err)
} else {
fmt.Println("Converted UTC Time:", customUTCFormat)
}
}
func TestConvertISOToCustomFormat(t *testing.T) {
isoTimeStr := "2024-08-30T14:00:00Z"
testData := dateFormatter{}
// 转换为自定义格式
customFormat, err := testData.ConvertISOToCustomFormat(isoTimeStr, "2006-01-02 15:04:05")
if err != nil {
fmt.Println("Error converting ISO time:", err)
} else {
fmt.Println("Converted Time:", customFormat)
}
// 另一个转换例子:只显示日期部分
customDateFormat, err := testData.ConvertISOToCustomFormat(isoTimeStr, "2006-01-02")
if err != nil {
fmt.Println("Error converting ISO time:", err)
} else {
fmt.Println("Converted Date:", customDateFormat)
}
}
func TestTimestampToTimeString(t *testing.T) {
testData := dateFormatter{}
timestamp := int64(1725002400)
layout := "2006-01-02 15:04:05"
formattedTime := testData.ConvertTimestampToTimeString(timestamp, layout)
fmt.Println("Formatted Time:", formattedTime)
}
func TestCalculateDateDifference(t *testing.T) {
testData := dateFormatter{}
days, err := testData.CalculateDateDifference("2024-08-30", "2024-09-05", "2006-01-02")
if err != nil {
fmt.Println("Error:", err)
} else {

}
}
func TestDateFormatMain(t *testing.T) {

}
}
func TestCompareDates(t *testing.T) {

} else {
fmt.Println("Comparison Result:", result)
}
}
func TestAddDaysToDate(t *testing.T) {
testData := dateFormatter{}
newDate, err := testData.AddDaysToDate("2024-08-30", 10, "2006-01-02")
if err != nil {

} else {

}
}
func TestConvertTimeRange(t *testing.T) {
// 示例1:将时间区间转换为Unix时间戳
testData := dateFormatter{}
startUnix, endUnix, err := testData.ConvertTimeRange("2024-08-30 14:00:00", "2024-09-01 18:00:00", "2006-01-02 15:04:05", "unix")
if err != nil {
fmt.Println("Error:", err)
} else {
fmt.Println("Start Unix Timestamp:", startUnix)
fmt.Println("End Unix Timestamp:", endUnix)
}
// 示例2:将时间区间转换为新的日期格式
startFormatted, endFormatted, err := testData.ConvertTimeRange("2024-08-30 14:00:00", "2024-09-01 18:00:00", "2006-01-02 15:04:05", "02-Jan-2006 03:04 PM")
if err != nil {

}
}
