type Logger

被弃用，实用LoggerV2

  1. type Logger interface {
  2.     Fatal(args ...interface{})
  3.     Fatalf(format string, args ...interface{})
  4.     Fatalln(args ...interface{})
  5.     Print(args ...interface{})
  6.     Printf(format string, args ...interface{})
  7.     Println(args ...interface{})
  8. }

type LoggerV2

LoggerV2为grpclog做底层日志工作

  1. type LoggerV2 interface {
  2.     // Info logs to INFO log. Arguments are handled in the manner of fmt.Print.
  3.     Info(args ...interface{})
  4.     // Infoln logs to INFO log. Arguments are handled in the manner of fmt.Println.
  5.     Infoln(args ...interface{})
  6.     // Infof logs to INFO log. Arguments are handled in the manner of fmt.Printf.
  7.     Infof(format string, args ...interface{})
  8.     // Warning logs to WARNING log. Arguments are handled in the manner of fmt.Print.
  9.     Warning(args ...interface{})
  10.     // Warningln logs to WARNING log. Arguments are handled in the manner of fmt.Println.
  11.     Warningln(args ...interface{})
  12.     // Warningf logs to WARNING log. Arguments are handled in the manner of fmt.Printf.
  13.     Warningf(format string, args ...interface{})
  14.     // Error logs to ERROR log. Arguments are handled in the manner of fmt.Print.
  15.     Error(args ...interface{})
  16.     // Errorln logs to ERROR log. Arguments are handled in the manner of fmt.Println.
  17.     Errorln(args ...interface{})
  18.     // Errorf logs to ERROR log. Arguments are handled in the manner of fmt.Printf.
  19.     Errorf(format string, args ...interface{})
  20.     // Fatal logs to ERROR log. Arguments are handled in the manner of fmt.Print.
  21.     // gRPC ensures that all Fatal logs will exit with os.Exit(1).
  22.     // Implementations may also call os.Exit() with a non-zero exit code.
  23.     Fatal(args ...interface{})
  24.     // Fatalln logs to ERROR log. Arguments are handled in the manner of fmt.Println.
  25.     // gRPC ensures that all Fatal logs will exit with os.Exit(1).
  26.     // Implementations may also call os.Exit() with a non-zero exit code.
  27.     Fatalln(args ...interface{})
  28.     // Fatalf logs to ERROR log. Arguments are handled in the manner of fmt.Printf.
  29.     // gRPC ensures that all Fatal logs will exit with os.Exit(1).
  30.     // Implementations may also call os.Exit() with a non-zero exit code.
  31.     Fatalf(format string, args ...interface{})
  32.     // V reports whether verbosity level l is at least the requested verbose level.
  33.     V(l int) bool
  34. }

func NewLoggerV2(infoW, warningW, errorW io.Writer) LoggerV2

  • 致命日志将写入errorW、warningW、infoW，然后是exit(1)。错误日志将写入errorW、warningW和infoW。警告日志将写入warningW和infoW。信息日志将写入infoW
