Overview ¶
Package httpunix provides a HTTP transport (net/http.RoundTripper) that uses Unix domain sockets instead of HTTP.
This is useful for non-browser connections within the same host, as it allows using the file system for credentials of both client and server, and guaranteeing unique names.
The URLs look like this:
http+unix://LOCATION/PATH_ETC
where LOCATION is translated to a file system path with Transport.RegisterLocation, and PATH_ETC follow normal http: scheme conventions.
Example (ClientIntegrated) ¶
package main
import (
"fmt"
"log"
"net/http"
"net/http/httputil"
"time"
"github.com/tv42/httpunix"
)
func main() {
// This example shows handling all net/http requests for the
// http+unix URL scheme.
u := &httpunix.Transport{
DialTimeout: 100 * time.Millisecond,
RequestTimeout: 1 * time.Second,
ResponseHeaderTimeout: 1 * time.Second,
}
u.RegisterLocation("myservice", "/path/to/socket")
// If you want to use http: with the same client:
t := &http.Transport{}
t.RegisterProtocol(httpunix.Scheme, u)
var client = http.Client{
Transport: t,
}
resp, err := client.Get("http+unix://myservice/urlpath/as/seen/by/server")
if err != nil {
log.Fatal(err)
}
buf, err := httputil.DumpResponse(resp, true)
if err != nil {
log.Fatal(err)
}
fmt.Printf("%s", buf)
resp.Body.Close()
}
Example (ClientStandalone) ¶
package main
import (
"fmt"
"log"
"net/http"
"net/http/httputil"
"time"
"github.com/tv42/httpunix"
)
func main() {
// This example shows using a customized http.Client.
u := &httpunix.Transport{
DialTimeout: 100 * time.Millisecond,
RequestTimeout: 1 * time.Second,
ResponseHeaderTimeout: 1 * time.Second,
}
u.RegisterLocation("myservice", "/path/to/socket")
var client = http.Client{
Transport: u,
}
resp, err := client.Get("http+unix://myservice/urlpath/as/seen/by/server")
if err != nil {
log.Fatal(err)
}
buf, err := httputil.DumpResponse(resp, true)
if err != nil {
log.Fatal(err)
}
fmt.Printf("%s", buf)
resp.Body.Close()
}
Example (Server) ¶
package main
import (
"log"
"net"
"net/http"
)
func main() {
l, err := net.Listen("unix", "/path/to/socket")
if err != nil {
log.Fatal(err)
}
defer l.Close()
if err := http.Serve(l, nil); err != nil {
log.Fatal(err)
}
}

Types ¶
type Transport ¶
type Transport struct {
// DialTimeout is deprecated. Use context instead.
DialTimeout time.Duration
// RequestTimeout is deprecated and has no effect.
RequestTimeout time.Duration
// ResponseHeaderTimeout is deprecated. Use context instead.
ResponseHeaderTimeout time.Duration
// contains filtered or unexported fields
}
Transport is a http.RoundTripper that connects to Unix domain sockets.
func (*Transport) RegisterLocation ¶
RegisterLocation registers an URL location and maps it to the given file system path.
Calling RegisterLocation twice for the same location is a programmer error, and causes a panic.
