Bind zap to context, built-in support for grpc.
go get github.com/acrazing/ctxzappackage main
import (
"context"
"github.com/acrazing/ctxzap"
"github.com/acrazing/ctxzap/grpc_zap"
"go.uber.org/zap"
"google.golang.org/grpc"
)
func main() {
// get your logger
logger := zap.NewExample()
// inject interceptors
_ = grpc.NewServer(
grpc.ChainUnaryInterceptor(
grpc_zap.UnaryServerInterceptor(logger, grpc_zap.WithAccessLog(true, true)),
),
grpc.ChainStreamInterceptor(
grpc_zap.StreamServerInterceptor(logger, grpc_zap.WithEventLog(true, true)),
),
)
// print log
// In any context based method called by grpc servers
_ = func(ctx context.Context) {
// add a field to the context, this field will always be printed in the next
// log calls with the context.
ctxzap.AddFields(ctx, zap.String("data", "1"))
// replace an existing field or append it to the context
ctxzap.ReplaceField(ctx, zap.String("data", "2"))
// print a log
ctxzap.Info(ctx, "call with data", zap.String("value", "2"))
