Caller Hook for Logrus 
使用hook的方式让Logrus拥有输出日志时输出源代码所在文件和行号功能
package main
import (
log "github.com/sirupsen/logrus"
caller "github.com/xdxiaodong/logrus-hook-caller"
)
func main() {
log.SetFormatter(new(log.JSONFormatter))
hook_caller := caller.NewHook(&caller.CallerHookOptions{
//DisabledField: true,
//EnableFile: true,
//EnableLine: true,
//Flags: caller.Llongfile,
})
log.AddHook(hook_caller)
log.Info("hello world")
}package main
import (
log "github.com/sirupsen/logrus"
caller "github.com/xdxiaodong/logrus-hook-caller"
)
func main() {
log.SetFormatter(new(log.JSONFormatter))
hook_caller := caller.NewHook(&caller.CallerHookOptions{
Flags: caller.Llongfile,
})
log.AddHook(hook_caller)
log.Info("hello world")
}
