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
