从字节数组中提取天数

Question

我有一个包含 Active Directory 调用输出的字节数组。我想解析它并提取我的帐户到期前的天数。现在我想知道：提取的最佳方法是什么22-4-2016 11:05:26（所以之后的值Password Expires）？

[]byte(`The request will be processed at a domain controller for domain local.nl.bol.com.

User name                    bla

Full Name                    bla bla

Comment

User's comment

Country code                 (null)

Password last set            13-3-2016 11:05:26

Password expires             22-4-2016 11:05:26

Password changeable          13-3-2016 11:05:26

Password required            Yes

User may change password     Yes

Workstations allowed         All

Logon script                 bla.bat

User profile

Home directory

Last logon                   31-3-2016 7:59:29

Logon hours allowed          All

The command completed successfully.`)

使用strings.TrimSpace，strings.Index并参考相关的stackoverflow答案，我得到了一个有效的解决方案，请在下面找到有效的代码：-package mainimport (    "fmt"    "strings")func CToGoString(c []byte) string {    n := -1    for i, b := range c {        if b == 0 {            break        }        n = i    }    return string(c[:n+1])}func main() {    s := []byte(`The request will be processed at a domain controller for domain local.nl.bol.com.User name                    blaFull Name                    bla blaCommentUser's commentCountry code                 (null)Account active               YesAccount expires              NeverPassword last set            13-3-2016 11:05:26Password expires             22-4-2016 11:05:26Password changeable          13-3-2016 11:05:26Password required            YesUser may change password     YesWorkstations allowed         AllLogon script                 bla.batUser profileHome directoryLast logon                   31-3-2016 7:59:29Logon hours allowed          AllThe command completed successfully.`)d := CToGoString(s)    len := len("Password expires")i := strings.Index(d, "Password expires")j := strings.Index(d, "Password changeable")chars := d[i+len:j]fmt.Println(strings.TrimSpace(chars))}已将代码发布到操场：http : //play.golang.org/p/t0Xjd04-pi

您可以通过将 []byte 转换为字符串，然后使用 strings 包查找并提取该值，最后使用 time.Parse 对其进行解析以将字符串转换为您可以使用的时间来实现。package mainimport (    "fmt"    "strings"    "time"    "log")func main() {    line := data[strings.Index(data, "Password expires"):strings.Index(data, "Password changeable")]    date := strings.TrimSpace(strings.TrimPrefix(line, "Password expires"))    fmt.Println(date)    pDate, err := time.Parse("02-1-2006 03:04:05", date)    if err != nil {        log.Fatal(err)    }    fmt.Println(pDate)}var data = string([]byte(`The request will be processed at a domain controller for domain local.nl.bol.com.User name                    blaFull Name                    bla blaCommentUser's commentCountry code                 (null)Account active               YesAccount expires              NeverPassword last set            13-3-2016 11:05:26Password expires             22-4-2016 11:05:26Password changeable          13-3-2016 11:05:26Password required            YesUser may change password     YesWorkstations allowed         AllLogon script                 bla.batUser profileHome directoryLast logon                   31-3-2016 7:59:29Logon hours allowed          AllThe command completed successfully.`))
