multiaddr 0.0.9

简单

from multiaddr import Multiaddr

# construct from a string
m1 = Multiaddr("/ip4/127.0.0.1/udp/1234")

# construct from bytes
m2 = Multiaddr(bytes_addr=m1.to_bytes())

assert str(m1) == "/ip4/127.0.0.1/udp/1234"
assert str(m1) == str(m2)
assert m1.to_bytes() == m2.to_bytes()
assert m1 == m2
assert m2 == m1
assert not (m1 != m2)
assert not (m2 != m1)

协议

from multiaddr import Multiaddr

m1 = Multiaddr("/ip4/127.0.0.1/udp/1234")

# get the multiaddr protocol description objects
m1.protocols()
# [Protocol(code=4, name='ip4', size=32), Protocol(code=17, name='udp', size=16)]

封装/解封装

from multiaddr import Multiaddr

m1 = Multiaddr("/ip4/127.0.0.1/udp/1234")
m1.encapsulate(Multiaddr("/sctp/5678"))
# <Multiaddr /ip4/127.0.0.1/udp/1234/sctp/5678>
m1.decapsulate(Multiaddr("/udp"))
# <Multiaddr /ip4/127.0.0.1>

隧道

Multiaddr允许非常优雅地表达隧道。

printer = Multiaddr("/ip4/192.168.0.13/tcp/80")
proxy = Multiaddr("/ip4/10.20.30.40/tcp/443")
printerOverProxy = proxy.encapsulate(printer)
print(printerOverProxy)
# /ip4/10.20.30.40/tcp/443/ip4/192.168.0.13/tcp/80

proxyAgain = printerOverProxy.decapsulate(printer)
print(proxyAgain)
# /ip4/10.20.30.40/tcp/443
