Functions

func LastHeaderValue

func LastHeaderValue(header http.Header, key string) string

LastHeaderValue gets the last value associated with the given key. It is case insensitive; textproto.CanonicalMIMEHeaderKey is used to canonicalize the provided key. If there are no values associated with the key, Get returns "".

Types

type RequestLogHandler

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

RequestLogHandler implements an http.Handler that writes request logs and calls the next handler.

func NewRequestLogHandler

func NewRequestLogHandler(h http.Handler, w io.Writer, templateStr string,
	inputGetter RequestLogTemplateInputGetter) (*RequestLogHandler, error)

NewRequestLogHandler creates an http.Handler that logs request logs to an io.Writer.

func (*RequestLogHandler) ServeHTTP

func (h *RequestLogHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

func (*RequestLogHandler) SetTemplate

func (h *RequestLogHandler) SetTemplate(templateStr string) error

SetTemplate sets the template to use for formatting request logs. Setting the template to an empty string turns of writing request logs.

type RequestLogResponse

type RequestLogResponse struct {
	Code    int
	Size    int
	Latency float64
}

RequestLogResponse provided response related information for the template execution.

type RequestLogRevision

type RequestLogRevision struct {
	Name          string
	Namespace     string
	Service       string
	Configuration string
	PodName       string
	PodIP         string
}

RequestLogRevision provides revision related static information for the template execution.

type RequestLogTemplateInput

type RequestLogTemplateInput struct {
	Request  *http.Request
	Response *RequestLogResponse
	Revision *RequestLogRevision
}

RequestLogTemplateInput is the wrapper struct that provides all necessary information for the template execution.

type RequestLogTemplateInputGetter

type RequestLogTemplateInputGetter func(req *http.Request, resp *RequestLogResponse) *RequestLogTemplateInput

RequestLogTemplateInputGetter defines a function returning the input to pass to a request log writer.

func RequestLogTemplateInputGetterFromRevision

func RequestLogTemplateInputGetterFromRevision(rev *RequestLogRevision) RequestLogTemplateInputGetter

RequestLogTemplateInputGetterFromRevision returns a func that forms a template input using a static revision information.

type ResponseRecorder

type ResponseRecorder struct {
	ResponseCode int
	ResponseSize int32
	// contains filtered or unexported fields
}

ResponseRecorder is an implementation of http.ResponseWriter and http.Flusher that captures the response code and size.

func NewResponseRecorder

func NewResponseRecorder(w http.ResponseWriter, responseCode int) *ResponseRecorder

NewResponseRecorder creates an http.ResponseWriter that captures the response code and size.

func (*ResponseRecorder) Flush

func (rr *ResponseRecorder) Flush()

Flush flushes the buffer to the client.

func (*ResponseRecorder) Header

func (rr *ResponseRecorder) Header() http.Header

Header returns the header map that will be sent by WriteHeader.

func (*ResponseRecorder) Hijack

func (rr *ResponseRecorder) Hijack() (net.Conn, *bufio.ReadWriter, error)

Hijack calls Hijack() on the wrapped http.ResponseWriter if it implements http.Hijacker interface, which is required for net/http/httputil/reverseproxy to handle connection upgrade/switching protocol. Otherwise returns an error.

func (*ResponseRecorder) Write

func (rr *ResponseRecorder) Write(p []byte) (int, error)

Write writes the data to the connection as part of an HTTP reply.

func (*ResponseRecorder) WriteHeader

func (rr *ResponseRecorder) WriteHeader(code int)

WriteHeader sends an HTTP response header with the provided status code.
