[songlong]

hi:
how to print function line when running?
Now I can see [10/18/19 15:35:43] [INFO] msg: 99
but I can get running line

_, file, line, ok = runtime.Caller(calldepth)

[songlong]

I found it can print in file
but cant not print console(stdout)
it is different in log4go?

console print:
[10/18/19 23:02:33] [INFO] kakaManageApi[version:1.0] start

log file:
