type Handler ¶
type Handler struct {
// contains filtered or unexported fields
}
Handler is an slog.Handler which helps standardize and correlate your logs by automatically adding the Trace ID and Span ID to your logs.
func (*Handler) WithAttrs ¶
WithAttrs implements the slog.Handler interface.
Example ¶
var buf bytes.Buffer
var h slog.Handler = NewHandler(slog.NewJSONHandler(&buf, &slog.HandlerOptions{}))
h = h.WithAttrs([]slog.Attr{slog.String("a", "b")})
logger := slog.New(h)
logger.Info("hello world")
var record struct {
Message string `json:"msg"`
A string `json:"a"`
}
err := json.Unmarshal(buf.Bytes(), &record)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(record.Message)
fmt.Print(record.A)
Output: hello world b
func (*Handler) WithGroup ¶
WithGroup implements the slog.Handler interface.
Example ¶
var buf bytes.Buffer
var h slog.Handler = NewHandler(slog.NewJSONHandler(&buf, &slog.HandlerOptions{}))
h = h.WithGroup("n")
logger := slog.New(h)
logger.Info("hello world", slog.Int("one", 1))
var record struct {
Message string `json:"msg"`
N struct {
One int `json:"one"`
} `json:"n"`
}
err := json.Unmarshal(buf.Bytes(), &record)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(record.Message)
fmt.Print(record.N.One)
Output: hello world 1
