Python requests“Max retries exceeded with url” error

1、增加重试连接次数

  requests.adapters.DEFAULT_RETRIES = 5

2、关闭多余的连接

requests使用了urllib3库，默认的http connection是keep-alive的，requests设置False关闭。

操作方法

s = requests.session()
s.keep_alive = False

3、只用session进行操作。即只创建一个连接，并设置最大连接数或者重试次数。

import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.retry import Retry


session = requests.Session()
retry = Retry(connect=3, backoff_factor=0.5)
adapter = HTTPAdapter(max_retries=retry)
session.mount('http://', adapter)
session.mount('https://', adapter)

session.get(url)

  import requests
    from requests.adapters import HTTPAdapter
    from requests.packages.urllib3.util.retry import Retry
    s = requests.Session()
    retry = Retry(connect = 5, backoff_factor = 1)
    adapter = HTTPAdapter(max_retries = retry)
    s.mount('http://', adapter)
    s.keep_alive = False
    res = s.post(self.conn.host + '/sign-in', data = json.dumps({
        'name': "XXX",
        'pwd': "XXX"
    }))
    response = res.json()

但是在starkoverflow上有人给出了这样的解释。

4.安装 py

pip install -U pyopenssl

5、设定固定的睡眠时间在发送请求之间
