vlog使用Golang原生日志库封装和实现io.Writer支持每天滚动压缩日志文件
- 基于实现 io.Writer。您可以轻松地在 golang log、GORM、grpclog 等中使用。
- 支持每日滚动日志，可以指定日志文件名的前缀，默认为进程名
- 旧文件压缩为gz格式
示例
要使用 vlog，您可以：
go get -u github.com/gngpp/vlog并像这样导入：
package main
import (
"github.com/gngpp/vlog"
"github.com/gngpp/vlog/timewriter"
)
func main() {
timeWriter := &timewriter.TimeWriter{
Dir: "./logs",
Compress: true,
ReserveDay: 30,
LogFilePrefix: "vlog",
}
log := vlog.New(timeWriter)
log.Info("hello vlog")
}如果需要全局设置输出：
package main
import (
"github.com/gngpp/vlog"
"github.com/gngpp/vlog/timewriter"
"io"
"os"
)
func main() {
timeWriter := &timewriter.TimeWriter{
Dir: "./logs",
Compress: true,
ReserveDay: 30,
LogFilePrefix: "vlog",
}
w := io.MultiWriter(os.Stdout, timeWriter)
// global settings
vlog.SetOutput(w)
logger := vlog.Default()
logger.Info("hello vlog")
}如果需要全局设置输出并同步到默认日志库：
package main
import (
"github.com/gngpp/vlog"
"github.com/gngpp/vlog/timewriter"
"io"
"log"
"os"
)
func main() {
timeWriter := &timewriter.TimeWriter{
Dir: "./logs",
Compress: true,
ReserveDay: 30,
LogFilePrefix: "vlog",
}
w := io.MultiWriter(os.Stdout, timeWriter)
// global settings
vlog.SetSyncOutput(true)
vlog.SetOutput(w)
logger := vlog.Default()
logger.Info("hello vlog")
log.Println("hello vlog")
}
