unixtransport

This package adds support for Unix domain sockets in Go HTTP clients.

t := &http.Transport{...}

unixtransport.Register(t)

client := &http.Client{Transport: t}

Now you can make requests with URLs like this:

resp, err := client.Get("https+unix:///path/to/socket:/request/path?a=b")

or

resp, err := client.Get("https+unix://@abstract/2:/request/path?a=b")

Use scheme http+unix or https+unix.

Inspiration taken from, and thanks given to, both tv42/httpunix and agorman/httpunix.

Overview

Functions

func Register

func Register(t *http.Transport)

Register adds a protocol handler to the provided transport that can serve requests to Unix domain sockets via the "http+unix" or "https+unix" schemes. Request URLs should have the following form:

https+unix:///path/to/socket:/request/path?query=val&...

The registered transport is based on a clone of the provided transport, and so uses the same configuration: timeouts, TLS settings, and so on. Connection pooling should also work as normal. One caveat: only the DialContext and DialTLSContext dialers are respected; the Dial and DialTLS dialers are explicitly removed and ignored.

Example (Custom)

package main

import (
	"net/http"

	"gitlab.com/opennota/unixtransport"
)

func main() {
	t := &http.Transport{
		// ...
	}

	unixtransport.Register(t)

	c := &http.Client{
		Transport: t,
		// ...
	}

	c.Get("https+unix:///tmp/my.sock")
}

Example (Default)

package main

import (
	"net/http"

	"gitlab.com/opennota/unixtransport"
)

func main() {
	// Register the "http+unix" and "https+unix" protocols in the default client transport.
	unixtransport.Register(http.DefaultTransport.(*http.Transport))

	// This will issue a GET request to an HTTP server listening at /tmp/my.sock.
	// Note the three '/' characters between 'http+unix:' and 'tmp'.
	http.Get("http+unix:///tmp/my.sock")

	// This shows how to include a request path and query.
	http.Get("http+unix:///tmp/my.sock:/users/123?q=abc")
}
