Function NewLoggerFromConfigString

internal/binarylog/env_config.go:45–58

NewLoggerFromConfigString reads the string and build a logger. It can be used to build a new logger and assign it to binarylog.Logger. Example filter config strings: - "" Nothing will be logged - "*" All headers and messages will be fully logged. - "*{h}" Only headers will be logged. - "*{m:256}" O

(s string)

// If two configs exist for one certain method or service, the one specified
// later overrides the previous config.
func NewLoggerFromConfigString(s string) Logger {
	if s == "" {
		return nil
	}
	l := newEmptyLogger()
	methods := strings.Split(s, ",")
	for _, method := range methods {
		if err := l.fillMethodLoggerWithConfigString(method); err != nil {
			grpclogLogger.Warningf("failed to parse binary log config: %v", err)
			return nil
		}
	}
	return l
}

// fillMethodLoggerWithConfigString parses config, creates TruncatingMethodLogger and adds
// it to the right map in the logger.
