Python中requests請求超時后自動重發

#  最終代碼

import requests
from requests.adapters import HTTPAdapter

s = requests.session()
s.mount('http://', HTTPAdapter(max_retries=3))
s.mount('https://', HTTPAdapter(max_retries=3))
import time
start_time = time.time()
try:
    s.get('https://www.google.com', timeout=10)
except BaseException as e:
    print(time.time()-start_time)

#    測試代碼

import requests
s = requests.session()
import time
start_time = time.time()
try:
    s.get('https://www.google.com', timeout=10)
except BaseException as e:
    print(time.time()-start_time)


一共耗時10秒

加上這里的四行代碼

from requests.adapters import HTTPAdapter
s = requests.session() s.mount('http://', HTTPAdapter(max_retries=3)) s.mount('https://', HTTPAdapter(max_retries=3))
--------------------------------------------------

import requests
from requests.adapters import HTTPAdapter s = requests.session() s.mount('http://', HTTPAdapter(max_retries=3)) s.mount('https://', HTTPAdapter(max_retries=3)) import time start_time = time.time() try: s.get('https://www.google.com', timeout=10) except BaseException as e: print(time.time()-start_time)

一共耗時40秒，第一連接超時后，后面會重新自動連接3次
