http

Documentation

Overview

Package http provides easy access to HcNet's best practices for building http servers. The primary method to use is `Serve`, which sets up an server that can support http/2 and can gracefully quit after receiving a SIGINT signal.

Constants

const DefaultListenAddr = "0.0.0.0:8080"

DefaultListenAddr represents the default address and port on which a server will listen, provided it is not overridden by setting the `ListenAddr` field on a `Config` struct.

const DefaultShutdownGracePeriod = 10 * time.Second

DefaultShutdownGracePeriod represents the default time in which the running process will allow outstanding http requests to complete before aborting them. It will be used when a grace period of 0 is used, which normally signifies "no timeout" to our graceful shutdown package. We choose not to provide a "no timeout" mode at present. Feel free to set the value to a year or something if you need a timeout that is effectively "no timeout"; We believe that most servers should use a sane timeout and prefer one for the default configuration.

Functions

func HeadersMiddleware

func HeadersMiddleware(headers stdhttp.Header, ignoredPrefixes ...string) func(next stdhttp.Handler) stdhttp.Handler

HeadersMiddleware sends headers

func LoggingMiddleware

func LoggingMiddleware(next stdhttp.Handler) stdhttp.Handler

LoggingMiddleware is a middleware that logs requests to the logger.

func NewAPIMux

func NewAPIMux(behindProxy bool) *chi.Mux

NewAPIMux returns a new server mux configured with the common defaults used for a web API in hcnet.

func NewMux

func NewMux(behindProxy bool) *chi.Mux

NewMux returns a new server mux configured with the common defaults used across all hcnet services.

func Run

func Run(conf Config)

Run starts an http server using the provided config struct.

This method configures the process to listen for termination signals (SIGINT and SIGTERM) to trigger a graceful shutdown by way of the graceful package (https://github.com/tylerb/graceful).

func StripTrailingSlashMiddleware

func StripTrailingSlashMiddleware(ignoredPrefixes ...string) func(next stdhttp.Handler) stdhttp.Handler

StripTrailingSlashMiddleware strips trailing slash.

Types

type Config

type Config struct {
	Handler             stdhttp.Handler
	ListenAddr          string
	TLS                 *config.TLS
	ShutdownGracePeriod time.Duration
	OnStarting          func()
	OnStopping          func()
	OnStopped           func()
}

Config represents the configuration of an http server that can be provided to `Run`.

type SimpleHTTPClientInterface

type SimpleHTTPClientInterface interface {
	PostForm(url string, data url.Values) (*stdhttp.Response, error)
	Get(url string) (*stdhttp.Response, error)
}

SimpleHTTPClientInterface helps mocking http.Client in tests
