UPNP报文示例

本文转载自  查看原文  2021-01-07 20:02  551    开发基础/ 基本功/ 分布式

经常用到内网穿透，对UPNP也有所了解，但是具体的报文每次都去抓显然浪费时间。因此记录在下面。
报文是开启BitComet时抓取的，前面的python代码是自己用来获取NOTIFY消息的代码。

目录

连接到组播地址接收NOTIFY消息

import socket
import re

ANY = "0.0.0.0"
DES_IP = "239.255.255.250"
PORT = 1900
# xml_str = b'<?xml version="1.0" encoding="utf-8"?><Probe><Uuid>B2D5D4D2-808C-40F6-87CD-694C05C2B274</Uuid><Types>inquiry</Types></Probe> '
# xml_str = b'<?xml version="1.0" encoding="utf-8"?><Probe><Uuid>CB09F608-E016-4EE8-869A-CA186852F12E</Uuid><Types>inquiry</Types></Probe> '
xml_str = b'M-SEARCH * HTTP/1.1\r\n' \
    + b'HOST: 239.255.255.250:1900\r\n' \
    + b'MAN: "ssdp:discover"\r\n' \
    + b'MX: 1\r\n' \
    + b'ST: urn:dial-multiscreen-org:service:dial:1\r\n' \
    + b'USER-AGENT: Google Chrome/87.0.4280.88 Windows\r\n\r\n\r\n'

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((ANY, PORT))
s.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 255)
s.setsockopt(
    socket.IPPROTO_IP,
    socket.IP_ADD_MEMBERSHIP,
    socket.inet_aton(DES_IP) + socket.inet_aton(ANY)
)
s.setblocking(False)
s.sendto(xml_str, (DES_IP, PORT))
while True:
    try:
        data, address = s.recvfrom(2048)
    except Exception as e:
        pass
    else:
        print(address)
        print(data)

调用的ipc的接口和接口顺序如下

调用ipc接口之后的结果

结论

添加映射的主要操作是POST的方式调用AddPortMapping接口。
显然libtorrent在这之前要先通过M-SEARCH和NOTIFY的UDP报文找到路由器，通过igd找ipc，通过ipc接口操作删除或添加映射。
添加完映射要用GetExternalIPAddress获取外网地址，这样就能把地址传给别人让别人找到你。
