Go has several integer types: uint8, uint16, uint32, uint64, int8, int16, int32 and int64. But strconv only support 3 of them which is int, int64 and uint64. So let's see how to use it. Parse string to int func main() { res, err := strconv.Atoi("10") if err != n...
Go convert string to time 本文主要以代码实例的形式,说明了Golang语言中,time对象和string对象之间的转换。 源码 package main import ( "fmt" "reflect" "time" ) func main() { fmt.Println("---当前时间/时间戳/字符串---") t := time.Now() timestamp := t.Unix() fmt.Println("当前本时区...
type saveLog func(msg string) //这个函数的第二个参数是一个函数 //这个函数将一个字符串转换为Int类型,如果失败了,则返回0,并输出错误。 func stringToInt(s string, log saveLog) int64 { if value, err := strconv.ParseInt(s, 0, 0); err != nil { log(err.Error()) return 0 } else {...
