Types

type CommonLogFormatter

type CommonLogFormatter struct{}

CommonLogFormatter provides formatting in the Traefik common log format

func (*CommonLogFormatter) Format

func (f *CommonLogFormatter) Format(entry *logrus.Entry) ([]byte, error)

Format formats the log entry in the Traefik common log format

type CoreLogData

type CoreLogData map[string]interface{}

CoreLogData holds the fields computed from the request/response.

type LogData

type LogData struct {
	Core               CoreLogData
	Request            http.Header
	OriginResponse     http.Header
	DownstreamResponse http.Header
}

LogData is the data captured by the middleware so that it can be logged.

func GetLogDataTable

func GetLogDataTable(req *http.Request) *LogData

GetLogDataTable gets the request context object that contains logging data. This creates data as the request passes through the middleware chain.

type LogHandler

type LogHandler struct {
	// contains filtered or unexported fields
}

LogHandler will write each request and its response to the access log.

func NewLogHandler

func NewLogHandler(config *types.AccessLog) (*LogHandler, error)

NewLogHandler creates a new LogHandler

func (*LogHandler) Close

func (l *LogHandler) Close() error

Close closes the Logger (i.e. the file, drain logHandlerChan, etc).

func (*LogHandler) Rotate

func (l *LogHandler) Rotate() error

Rotate closes and reopens the log file to allow for rotation by an external source.

func (*LogHandler) ServeHTTP

func (l *LogHandler) ServeHTTP(rw http.ResponseWriter, req *http.Request, next http.HandlerFunc)

type SaveBackend

type SaveBackend struct {
	// contains filtered or unexported fields
}

SaveBackend sends the backend name to the logger. These are always used with a corresponding SaveFrontend handler.

func (*SaveBackend) ServeHTTP

func (sb *SaveBackend) ServeHTTP(rw http.ResponseWriter, r *http.Request)

type SaveFrontend

type SaveFrontend struct {
	// contains filtered or unexported fields
}

SaveFrontend sends the frontend name to the logger. These are sometimes used with a corresponding SaveBackend handler, but not always. For example, redirected requests don't reach a backend.

func (*SaveFrontend) ServeHTTP

func (sf *SaveFrontend) ServeHTTP(rw http.ResponseWriter, r *http.Request)

type SaveNegroniBackend added in v1.6.0

type SaveNegroniBackend struct {
	// contains filtered or unexported fields
}

SaveNegroniBackend sends the backend name to the logger.

func (sb *SaveNegroniBackend) ServeHTTP(rw http.ResponseWriter, r *http.Request, next http.HandlerFunc)

type SaveNegroniFrontend

type SaveNegroniFrontend struct {
	// contains filtered or unexported fields
}

SaveNegroniFrontend sends the frontend name to the logger.

func (*SaveNegroniFrontend) ServeHTTP

func (sf *SaveNegroniFrontend) ServeHTTP(rw http.ResponseWriter, r *http.Request, next http.HandlerFunc)

type SaveNegroniUsername added in v1.7.4

type SaveNegroniUsername struct {
	// contains filtered or unexported fields
}

SaveNegroniUsername adds the Username to the access logger data table.

func (*SaveNegroniUsername) ServeHTTP added in v1.7.4

func (sf *SaveNegroniUsername) ServeHTTP(rw http.ResponseWriter, r *http.Request, next http.HandlerFunc)

type SaveRetries
