How to get rid of Spaces between logs when using 'logrus' package

问题

所以我开始使用'logrus'。
我将它设置在我自己的日志记录器包中，看起来像这样：

  1. package logger
  3. import (
  4.     log "github.com/Sirupsen/logrus"
  5. )
  7. func InitLogger() {
  8.     var textFormatter = new(log.TextFormatter)
  9.     textFormatter.TimestampFormat = "2006-01-02 15:04:05"
  10.     textFormatter.ForceColors = true
  11.     textFormatter.FullTimestamp = true
  13.     log.SetFormatter(textFormatter)
  14. }
  16. func Printf(format string, v ...interface{}) {
  17.     log.Printf(format, v...)
  18. }
  20. func Fatalf(format string, v ...interface{}) {
  21.     log.Fatalf(format, v...)
  22. }
  24. func Panicf(format string, v ...interface{}) {
  25.     log.Panicf(format, v...)
  26. }
  28. func Debugf(format string, v ...interface{}) {
  29.     log.Debugf(format, v...)
  30. }

（对于所有logrus日志函数都是这样的，不必在这里粘贴所有内容，但你明白我的意思...）

在我的项目中使用它：

  1. import (
  2.     log "logger"
  3. )

除了日志之间有空行之外，一切都很顺利：

  1. INFO[2016-04-16 17:32:51] pathPrefix: /app/
  2. pathValue: {js ./app/}
  4. INFO[2016-04-16 17:32:51] pathPrefix: /node_modules/
  5. pathValue: {js ./node_modules/}
  7. INFO[2016-04-16 17:32:51] Listening for HTTP on tcp (0.0.0.0:8080)
  8. INFO[2016-04-16 17:38:02] Starting HomeHandler
  9. INFO[2016-04-16 17:38:02] GET / Index 4.769735ms
  11. INFO[2016-04-16 17:38:02] Starting AuthCheckHandler
  12. ERRO[2016-04-16 17:38:02] Failed getting cookie from user: http: named cookie not present
  14. INFO[2016-04-16 17:38:02] GET /auth AuthCheckHandler 67.79μs
  16. INFO[2016-04-16 17:38:02] Starting AuthCheckHandler
  17. ERRO[2016-04-16 17:38:02] Failed getting cookie from user: http: named cookie not present
  19. INFO[2016-04-16 17:38:02] GET /auth AuthCheckHandler 82.195μs

如何去掉这些空行？
在文档/谷歌和这里都找不到解决方案，所以我认为我可能是漏掉了一些非常愚蠢的东西...

谢谢。

英文:

So I started using 'logrus'.
I set it in my own logger package which looks like this:

  1.     package logger
  3. import(
  4.      log "github.com/Sirupsen/logrus"
  6. )
  9. func InitLogger() {
  10.     var textFormatter = new(log.TextFormatter)
  11.     textFormatter.TimestampFormat = "2006-01-02 15:04:05"
  12.     textFormatter.ForceColors = true
  13.     textFormatter.FullTimestamp = true
  15.     log.SetFormatter(textFormatter)
  16. }
  19. func Printf(format string, v ...interface{}) {
  20.     log.Printf(format, v...)
  21. }
  23. func Fatalf(format string, v ...interface{}) {
  24.     log.Fatalf(format, v...)
  25. }
  27. func Panicf(format string, v ...interface{}) {
  28.     log.Panicf(format, v...)
  29. }
  31. func Debugf(format string, v ...interface{}) {
  32.     log.Debugf(format, v...)

(it goes like this for all logrus log functions, dont see the
point of pasting all of them here, but you get the idea...)

Use it across my project as:

  1. import(
  2.     log "logger"
  3. )

And everything is peachy except logs being printed with line spaces between them:

  1. INFO[2016-04-16 17:32:51] pathPrefix: /app/
  2. pathValue: {js ./app/}
  3.     
  4. INFO[2016-04-16 17:32:51] pathPrefix: /node_modules/
  5. pathValue: {js ./node_modules/}
  6.  
  7. INFO[2016-04-16 17:32:51] Listening for HTTP on tcp (0.0.0.0:8080)     
  8. INFO[2016-04-16 17:38:02] Starting HomeHandler                         
  9. INFO[2016-04-16 17:38:02] GET / Index 4.769735ms
  10.                       
  11. INFO[2016-04-16 17:38:02] Starting AuthCheckHandler                    
  12. ERRO[2016-04-16 17:38:02] Failed getting cookie from user: http: named cookie not present
  13.  
  14. INFO[2016-04-16 17:38:02] GET /auth AuthCheckHandler 67.79µs
  15.           
  16. INFO[2016-04-16 17:38:02] Starting AuthCheckHandler                    
  17. ERRO[2016-04-16 17:38:02] Failed getting cookie from user: http: named cookie not present
  18.  
  19. INFO[2016-04-16 17:38:02] GET /auth AuthCheckHandler 82.195µs

How can I get rid of those spaces?
Couldn't find any solution in documentation/google nor here
so I assume its something very silly that I am missing...

Thanks

似乎在传递字符串格式时，你传递了换行符。

  1. func main() {
  2.   x := 0
  3.   logger.InitLogger()
  5.   logger.Printf("%s", "TEST1")
  6.   logger.Printf("%s", "TEST2")
  8.   if x == 0 {
  9.     logger.Printf("%s", "TEST3")
  10.     logger.Printf("%s", "TEST4")
  11.     logger.Printf("%s", "TEST5")
  12.   }
  13. }

返回结果：

  1. go run main.go
  2. INFO[2016-04-16 12:40:30] TEST1
  3. INFO[2016-04-16 12:40:30] TEST2
  4. INFO[2016-04-16 12:40:30] TEST3
  5. INFO[2016-04-16 12:40:30] TEST4
  6. INFO[2016-04-16 12:40:30] TEST5
英文:

Seems like you are passing newlines when you pass your string formatting.

  1. func main() {
  3.   x := 0
  4.   logger.InitLogger()
  6.   logger.Printf("%s", "TEST1")
  7.   logger.Printf("%s", "TEST2")
  9.   if x == 0 {
  10. 	  logger.Printf("%s", "TEST3")
  11. 	  logger.Printf("%s", "TEST4")
  12. 	  logger.Printf("%s", "TEST5")
  13.   }
  14. }

Returns:

  1. go run main.go
  2. INFO[2016-04-16 12:40:30] TEST1
  3. INFO[2016-04-16 12:40:30] TEST2
  4. INFO[2016-04-16 12:40:30] TEST3
  5. INFO[2016-04-16 12:40:30] TEST4
  6. INFO[2016-04-16 12:40:30] TEST5

你确定你没有意外地在发送给日志记录器包的某些消息中包含换行符吗？

英文:

Are you sure you aren't accidentally including new lines in some of the messages you are sending to your logger package?
