1.[]byte转为string:
package main import ( "fmt" ) func main() { data := [4]byte{0x31, 0x32, 0x33, 0x34} str := string(data[:]) fmt.Println(str) }
输出:
1234
2.string 转为int64类型
package main import ( "fmt" "strconv" ) func main() { total, _ := strconv.ParseInt("50", 10, 64) fmt.Println(total) }
输出:
50
3.golang格式化为当前时间日期:
package main import ( "fmt" "time" ) func main() { nowTime := time.Now() //2006-01-02 15:04:05 此为固定用法,相当于php语言的Y-m-d H:i:s fmt.Println(nowTime.Format("2006-01-02 15:04:05")) }
输出:
2019-08-18 16:54:57
4.返回当前本地时间:
package main import ( "fmt" "time" ) func main() { fmt.Println(time.Now()) }
输出:
2019-08-18 16:57:23.3661001 +0800 CST m=+0.013000801
5.返回当前本地时间戳:
package main import ( "fmt" "time" ) func main() { fmt.Println(time.Now().Unix()) }
输出:
1566118750
6.给定时间戳和日期字符串转为golang标准时间:
package main import ( "fmt" "time" ) func main() { //给定日期字符串 nowTime := time.Now() //2006-01-02 15:04:05 此为固定用法,相当于php语言的Y-m-d H:i:s x := nowTime.Format("2006-01-02 15:04:05") p, _ := time.Parse("2006-01-02 15:04:05", x) fmt.Println(p) //给定时间戳 timestamp := time.Now().Unix() fmt.Println(time.Unix(timestamp, 0)) }
输出:
2019-08-18 17:00:16 +0000 UTC
2019-08-18 17:00:16 +0800 CST
7.计算程序运行时间:
package main import ( "fmt" "time" ) func main() { t1 := time.Now() time.Sleep(time.Second * 2) elapsed := time.Since(t1) fmt.Println("程序运行时间为: ", elapsed) }
输出:
程序运行时间为: 2.0001144s
