Short Description
A reasonably complete and well-tested golang port of httpbin
Full Description

go-httpbin

A reasonably complete and well-tested golang port of Kenneth Reitz's
httpbin service, with zero dependencies outside the go stdlib.



Usage

Run as a standalone binary, configured by command line flags or environment
variables:

$ go-httpbin -help
Usage of ./dist/go-httpbin:
  -max-duration duration
        Maximum duration a response may take (default 10s)
  -max-memory int
        Maximum size of request or response, in bytes (default 1048576)
  -port int
        Port to listen on (default 8080)

Docker images are published to Docker Hub:

$ docker run -P mccutchen/go-httpbin

The github.com/mccutchen/go-httpbin/httpbin package can also be used as a
library for testing an applications interactions with an upstream HTTP service,
like so:

package httpbin_test

import (
    "net/http"
    "net/http/httptest"
    "testing"
    "time"

    "github.com/mccutchen/go-httpbin/httpbin"
)

func TestSlowResponse(t *testing.T) {
    handler := httpbin.NewHTTPBin().Handler()
    srv := httptest.NewServer(handler)
    defer srv.Close()

    client := http.Client{
        Timeout: time.Duration(1 * time.Second),
    }
    _, err := client.Get(srv.URL + "/delay/10")
    if err == nil {
        t.Fatal("expected timeout error")
    }
}

Installation

go get github.com/mccutchen/go-httpbin/...

Motivation & prior art

I've been a longtime user of Kenneith Reitz's original
httpbin.org, and wanted to write a golang port for fun and to
see how far I could get using only the stdlib.

When I started this project, there were a handful of existing and incomplete
golang ports, with the most promising being ahmetb/go-httpbin. This
project showed me how useful it might be to have an httpbin library
available for testing golang applications.

Known differences from other httpbin versions

Compared to the original:

  • No /brotli endpoint (due to lack of support in Go's stdlib)
  • The ?show_env=1 query param is ignored (i.e. no special handling of
    runtime environment headers)
  • Response values which may be encoded as either a string or a list of strings
    will always be encoded as a list of strings (e.g. request headers, query
    params, form values)

Compared to ahmetb/go-httpbin:

  • No dependencies on 3rd party packages
  • More complete implementation of endpoints
