自定义输出格式
package cclog
import (
"bytes"
"fmt"
"strings"
"github.com/sirupsen/logrus"
)
type Formatter struct{}
func (f *Formatter) Format(entry *logrus.Entry) ([]byte, error) {
var out string
if entry.HasCaller() {
var pkg bytes.Buffer
for _, t := range strings.Split(entry.Caller.File, "/") {
if len(t) == 0 {
continue;
}
pkg.WriteString(t[:1])
pkg.WriteString(".")
}
pkg.WriteString(entry.Caller.Function)
out = fmt.Sprintf("[%s][%s] %s(%d) %s\n", entry.Level.String()[:4], entry.Time.Format("2006-01-02 15:03:04.000"), pkg.String(), entry.Caller.Line, entry.Message)
} else {
out = fmt.Sprintf("[%s][%s] %s\n", entry.Level.String()[:4], entry.Time.Format("2006-01-02 15:03:04.000"), entry.Message)
}
return []byte(out), nil
}
配置类
import (

)
func init() {
log.SetFormatter(new(cclog.Formatter))
log.SetReportCaller(true)
log.SetOutput(&lumberjack.Logger{
Filename: "./logs/api.log",
MaxSize: 100, // megabytes
MaxBackups: 3,
MaxAge: 28, // days
Compress: true, // disabled by default
})
// log.SetOutput(os.Stdout)
log.SetLevel(log.DebugLevel)
}
func main() {
r := gin.Default()
r.GET("/app", handleApp)
r.Run(":80")
}
func handleApp(c *gin.Context) {
log.Info("good luck")
c.JSON(200, gin.H{"code": 300, "msg": "OK"})
}
打印输出:
[info][2019-09-10 15:03:50.330] D.g.s.h.m.main.handleApp(67) good luck
