string - Go，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。我想对此进行解析并提取帐户到期前的天数。现在我想知道:提取 22-4-2016 11:05:26 的最佳方法是什么(所以 Password Expires 之后的值)？

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

User name                    bla
Full Name                    bla bla

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 并引用相关的 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 main

import (
    "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.

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))
}
