Send HTTP requests using python-requests with timeout, tcp reuse(session) and retry.

decent_request.py

from requests.adapters import HTTPAdapter, Retry
from requests import Session

retries = Retry(
  total=5, backoff_factor=1, status_forcelist=[502, 503, 504]
)
session = Session()  # reuse tcp connection
session.mount("http://", HTTPAdapter(max_retries=retries))
session.mount("https://", HTTPAdapter(max_retries=retries))

session.get("https://example.com", timeout=5)  # seconds

以及, 如 https://t.me/laiskynotes/100 这条提到的, 如果你请求的是个很慢的服务器 (比如每 3s 给你返回一个字节),
那实际的请求时间可能远大于 timeout
