Python中requests请求超时后自动重发

#  最终代码

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)

#    测试代码

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)


一共耗时10秒

加上这里的四行代码

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)

一共耗时40秒，第一连接超时后，后面会重新自动连接3次
