Ciro IP na wakili da tashoshin hex daga JSON da aka sa a ciki

Teburin HTML mara komai ba koyaushe yake nufin amsar ba ta da rikodin wakili ba. Wasu jerin suna sanya abubuwan JSON cikin kiran JavaScript kuma suna cika layukan daga baya.

Ga tushen da aka riga aka samo wanda ke amfani da takamaiman murfin gp.insertPrx sannan abin JSON:

import ipaddress
import json
import re

decoder = json.JSONDecoder()
endpoints = set()
for marker in re.finditer(r"gp[.]insertPrx\(\s*", html):
    try:
        row, end = decoder.raw_decode(html, marker.end())
        if not isinstance(row, dict):
            continue
        address = ipaddress.ip_address(row["PROXY_IP"])
        port = int(row["PROXY_PORT"], 16)
    except (ValueError, KeyError, TypeError):
        continue
    if 1 <= port <= 65535 and html[end:].lstrip().startswith(");"):
        endpoints.add((str(address), port))

html shine rubutun tushen, ba abin burauza ba. Maganar yau da kullum tana gano sanannen murfi; JSONDecoder yana ƙayyade inda darajar JSON ta ƙare. Wannan yana guje wa ƙoƙarin nazarin JSON mai zurfi da maganar yau da kullum kawai.
