Go, extract days out of byte array

问题

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的天数。现在我想知道：提取22-4-2016 11:05:26（即Password Expires之后的值）的最佳方法是什么？

  1. []byte(`The request will be processed at a domain controller for domain local.nl.bol.com.
  3. User name                    bla
  4. Full Name                    bla bla
  5. Comment
  6. User's comment
  7. Country code                 (null)
  8. Account active               Yes
  9. Account expires              Never
  11. Password last set            13-3-2016 11:05:26
  12. Password expires             22-4-2016 11:05:26
  13. Password changeable          13-3-2016 11:05:26
  14. Password required            Yes
  15. User may change password     Yes
  17. Workstations allowed         All
  18. Logon script                 bla.bat
  19. User profile
  20. Home directory
  21. Last logon                   31-3-2016 7:59:29
  23. Logon hours allowed          All
  25. The command completed successfully.`)

I have a byte array containing the output of an Active Directory call. I want to parse this and extract the amount of days until my account expires. Now I'm wondering: what's the best way to extract 22-4-2016 11:05:26 (so the value after Password Expires)?

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

使用strings.TrimSpace、strings.Index并参考相关的stackoverflow答案，我得到了一个可行的解决方案，请查看下面的工作代码：

  1. package main
  3. import (
  4.     "fmt"
  5.     "strings"
  6. )
  8. func CToGoString(c []byte) string {
  9.     n := -1
  10.     for i, b := range c {
  11.         if b == 0 {
  12.             break
  13.         }
  14.         n = i
  15.     }
  16.     return string(c[:n+1])
  17. }
  19. func main() {
  21.     s := []byte(`The request will be processed at a domain controller for domain local.nl.bol.com.
  23. User name                    bla

你可以通过将[]byte转换为字符串，然后使用strings包来查找和提取值，最后使用time.Parse将字符串解析为可操作的时间。

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"strings"
  6. 	"time"
  7. 	"log"
  8. )
  10. func main() {
  11. 	line := data[strings.Index(data, "Password expires"):strings.Index(data, "Password changeable")]
  12. 	date := strings.TrimSpace(strings.TrimPrefix(line, "Password expires"))
  13. 	fmt.Println(date)
  14. 	pDate, err := time.Parse("02-1-2006 03:04:05", date)
  15. 	if err != nil {
  16. 		log.Fatal(err)
  17. 	}
  18. 	fmt.Println(pDate)
  19. }
  21. var data = string([]byte(`The request will be processed at a domain controller for domain local.nl.bol.com.
  23. User name                    bla
  24. Full Name                    bla bla
  25. Comment
  26. User's comment
  27. Country code                 (null)
  28. Account active               Yes
  29. Account expires              Never
  31. Password last set            13-3-2016 11:05:26
  32. Password expires             22-4-2016 11:05:26
  33. Password changeable          13-3-2016 11:05:26
  34. Password required            Yes
  35. User may change password     Yes
  37. Workstations allowed         All
  38. Logon script                 bla.bat
  39. User profile
  40. Home directory
  41. Last logon                   31-3-2016 7:59:29
  43. Logon hours allowed          All

英文:

You can do it by converting the []byte into a string and then using the strings package to find and extract the value and finally parsing it with time.Parse to convert the string to a time that you can work with.

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"strings"
  6. 	"time"
  7. 	"log"
  8. )
  10. func main() {
  11. 	line := data[strings.Index(data, "Password expires"):strings.Index(data, "Password changeable")]
  12. 	date := strings.TrimSpace(strings.TrimPrefix(line, "Password expires"))
  13. 	fmt.Println(date)
  14. 	pDate, err := time.Parse("02-1-2006 03:04:05", date)
  15. 	if err != nil {
  16. 		log.Fatal(err)
  17. 	}
  18. 	fmt.Println(pDate)
  19. }
  21. var data = string([]byte(`The request will be processed at a domain controller for domain local.nl.bol.com.
  23. User name                    bla
  24. Full Name                    bla bla
  25. Comment
  26. User's comment
  27. Country code                 (null)
  28. Account active               Yes
  29. Account expires              Never
  31. Password last set            13-3-2016 11:05:26
  32. Password expires             22-4-2016 11:05:26
  33. Password changeable          13-3-2016 11:05:26
  34. Password required            Yes
  35. User may change password     Yes
  37. Workstations allowed         All
  38. Logon script                 bla.bat
  39. User profile
  40. Home directory
  41. Last logon                   31-3-2016 7:59:29
