go-multiaddr

multiaddr implementation in go

Multiaddr is a standard way to represent addresses that:

Support any standard network protocols.
Self-describe (include protocols).
Have a binary packed format.
Have a nice string representation.
Encapsulate well.

Usage

Example

Simple

import ma "github.com/multiformats/go-multiaddr"

// construct from a string (err signals parse failure)
m1, err := ma.NewMultiaddr("/ip4/127.0.0.1/udp/1234")

// construct from bytes (err signals parse failure)
m2, err := ma.NewMultiaddrBytes(m1.Bytes())

// true
strings.Equal(m1.String(), "/ip4/127.0.0.1/udp/1234")
strings.Equal(m1.String(), m2.String())
bytes.Equal(m1.Bytes(), m2.Bytes())
m1.Equal(m2)
m2.Equal(m1)

Protocols

// get the multiaddr protocol description objects
m1.Protocols()
// []Protocol{
//   Protocol{ Code: 4, Name: 'ip4', Size: 32},
//   Protocol{ Code: 17, Name: 'udp', Size: 16},
// }

En/decapsulate

import ma "github.com/multiformats/go-multiaddr"

m, err := ma.NewMultiaddr("/ip4/127.0.0.1/udp/1234")
// <Multiaddr /ip4/127.0.0.1/udp/1234>

sctpMA, err := ma.NewMultiaddr("/sctp/5678")

m.Encapsulate(sctpMA)
// <Multiaddr /ip4/127.0.0.1/udp/1234/sctp/5678>

udpMA, err := ma.NewMultiaddr("/udp/1234")

m.Decapsulate(udpMA) // up to + inc last occurrence of subaddr
// <Multiaddr /ip4/127.0.0.1>

Tunneling

Multiaddr allows expressing tunnels very nicely.

printer, _ := ma.NewMultiaddr("/ip4/192.168.0.13/tcp/80")
proxy, _ := ma.NewMultiaddr("/ip4/10.20.30.40/tcp/443")
printerOverProxy := proxy.Encapsulate(printer)
// /ip4/10.20.30.40/tcp/443/ip4/192.168.0.13/tcp/80

proxyAgain := printerOverProxy.Decapsulate(printer)
// /ip4/10.20.30.40/tcp/443
