var _ hlog.FullLogger = (*Logger)(nil)
// Logger logrus impl
type Logger struct {
l *logrus.Logger
}
NewLogger
NewLogger
uses defaultConfig()
to create and initialize a Logger. The required configuration can be passed into the function as a parameter. If no parameter is passed in, the initial configuration will be installed to create Logger
For related configuration, please refer to “option configuration” below.
Function Signature:
func NewLogger(opts ...Option) *Logger
Sample code:
package main
import (
hertzlogrus "github.com/hertz-contrib/logger/logrus"
"github.com/sirupsen/logrus"
)
func main() {
logger := hertzlogrus.NewLogger(hertzlogrus.WithLogger(logrus.New()))
}
Option configuration
WithLogger
WithLogger
passes logrus.Logger into configuration
Function Signature:
func WithLogger(logger *logrus.Logger) Option
Sample code:
package main
import (
hertzlogrus "github.com/hertz-contrib/logger/logrus"
"github.com/sirupsen/logrus"
)
func main() {
stdLogger := logrus.StandardLogger()
l:=hertzlogrus.NewLogger(hertzlogrus.WithLogger(stdLogger))
}
WithHook
WithHook
adds the incoming logrus.Hook to the hook in the configuration
Function Signature:
func WithHook(hook logrus.Hook) Option
Sample code:
package main
import (
hertzlogrus "github.com/hertz-contrib/logger/logrus"
"github.com/sirupsen/logrus"
)
func main() {
var h logrus.Hook
l := hertzlogrus.NewLogger(hertzlogrus.WithHook(h))
l.Info("Foo")
l.Warn("Bar")
//h.logs[0].level==zerolog.InfoLevel
//h.logs[0].message=="Foo"
//h.logs[1].level==zerolog.WarnLevel
//h.logs[1].message=="Bar"
}

}
logger := hertzlogrus.NewLogger()
// Provides compression and deletion
lumberjackLogger := &lumberjack.Logger{
Filename: fileName,
MaxSize: 20, // A file can be up to 20M.
MaxBackups: 5, // Save up to 5 files at the same time.
MaxAge: 10, // A file can be saved for up to 10 days.
Compress: true, // Compress with gzip.
}
logger.SetOutput(lumberjackLogger)
logger.SetLevel(hlog.LevelDebug)
hlog.SetLogger(logger)
h.GET("/hello", func(ctx context.Context, c *app.RequestContext) {
hlog.Info("Hello, hertz")
c.String(consts.StatusOK, "Hello hertz!")
})
h.Spin()
}
