How klog logs to stdout as well as files files
问题
我正在为一个使用klog库进行日志记录的项目工作，并且我希望能够将日志写入终端，同时也能够写入文件以便在重新启动或停机期间查看。
我通过以下代码进行了测试，但它只能将日志写入文件，而不能同时输出到终端：
package main
import (
"flag"
"k8s.io/klog/v2"
)
func init() {
var fs flag.FlagSet
klog.InitFlags(&fs)
fs.Set("logtostderr", "false")
fs.Set("log_file_max_size", "1000")
fs.Set("log_file", "/home/test/workspace/test/test.log")
}
func main() {
defer klog.Flush()
klog.Info("test")
}
我该如何实现这个功能？非常感谢您的帮助。
英文:
I'm working on a project that uses the klog library for logging, and I want to be able to write the logs to a **terminal** while being able to write to a **file** for viewing on reboot or downtime.
I tested through the following code, but it can only write to the file and not output at the terminal at the same time
package main
import (
"flag"
"k8s.io/klog/v2"
)
func init() {
func init() {
var fs flag.FlagSet
klog.InitFlags(&fs)
fs.Set("logtostderr", "false")
fs.Set("log_file_max_size", "1000")
fs.Set("log_file", "/home/test/workspace/test/test.log")
}
}
func main() {
defer klog.Flush()
klog.Info("test")
}
How can I get it? I really appreciate any help with this.

如果你阅读Klog文档，它提到支持一个标志-alsologtostderr：
-alsologtostderr=false
日志会同时写入标准错误和文件。
看起来这个标志可以满足你的需求。
英文:
If you read the Klog documentation says that it supports a flag, -alsologtostderr:
> -alsologtostderr=false<br/>
> Logs are written to standard error as well as to files.
Seems like that would do you.
