|
||
|
|
|
||
|
|
### Structured logging
|
||
|
|
|
||
|
|
```go
|
||
|
|
logger := log.NewStdLogger(os.Stdout)
|
||
|
|
// fields & valuer
|
||
|
|
logger = log.With(logger,
|
||
|
|
"service.name", "hellworld",
|
||
|
|
"service.version", "v1.0.0",
|
||
|
|
"ts", log.DefaultTimestamp,
|
||
|
|
"caller", log.DefaultCaller,
|
||
|
|
)
|
||
|
|
logger.Log(log.LevelInfo, "key", "value")
|
||
|
|
|
||
|
|
// helper
|
||
|
|
helper := log.NewHelper(logger)
|
||
|
|
helper.Log(log.LevelInfo, "key", "value")
|
||
|
|
helper.Info("info message")
|
||
|
|
helper.Infof("info %s", "message")
|
||
|
|
helper.Infow("key", "value")
|
||
|
|
|
||
|
|
// filter
|
||
|
|
log := log.NewHelper(log.NewFilter(logger,
|
||
|
|
log.FilterLevel(log.LevelInfo),
|
||
|
|
log.FilterKey("foo"),
|
||
|
|
log.FilterValue("bar"),
|
||
|
|
log.FilterFunc(customFilter),
|
||
|
|
))
|
||
|
|
log.Debug("debug log")
|
||
|
|
log.Info("info log")
|
||
|
|
log.Warn("warn log")
|
||
|
|
log.Error("warn log")
|
||
|
|
```
