    func NewReporter

    func NewReporter(url string, opts ...ReporterOption) reporter.Reporter

      NewReporter returns a new HTTP Reporter. url should be the endpoint to send the spans to, e.g. http://localhost:9411/api/v2/spans


      type HTTPDoer

      type HTTPDoer interface {
      	Do(req *http.Request) (*http.Response, error)

        HTTPDoer will do a request to the Zipkin HTTP Collector

        type ReporterOption

        type ReporterOption func(r *httpReporter)

          ReporterOption sets a parameter for the HTTP Reporter

          func BatchInterval

          func BatchInterval(d time.Duration) ReporterOption

            BatchInterval sets the maximum duration we will buffer traces before emitting them to the collector. The default batch interval is 1 second.

            func BatchSize

            func BatchSize(n int) ReporterOption

              BatchSize sets the maximum batch size, after which a collect will be triggered. The default batch size is 100 traces.

              func Client

              func Client(client HTTPDoer) ReporterOption

                Client sets a custom http client to use under the interface HTTPDoer which includes a `Do` method with same signature as the *http.Client

                func Logger

                func Logger(l *log.Logger) ReporterOption

                  Logger sets the logger used to report errors in the collection process.

                  func MaxBacklog

                  func MaxBacklog(n int) ReporterOption

                    MaxBacklog sets the maximum backlog size. When batch size reaches this threshold, spans from the beginning of the batch will be disposed.

                    func RequestCallback

                    func RequestCallback(rc RequestCallbackFn) ReporterOption

                      RequestCallback registers a callback function to adjust the reporter *http.Request before it sends the request to Zipkin.

                      func Serializer

                      func Serializer(serializer reporter.SpanSerializer) ReporterOption

                        Serializer sets the serialization function to use for sending span data to Zipkin.

                        func Timeout

                        func Timeout(duration time.Duration) ReporterOption

                          Timeout sets maximum timeout for the http request through its context.

                          type RequestCallbackFn

                          type RequestCallbackFn func(*http.Request)

                            RequestCallbackFn receives the initialized request from the Collector before sending it over the wire. This allows one to plug in additional headers or do other customization.
