请求中的URL超过了最大重试次数

我试图获得应用商店>业务的内容:

import requests
from lxml import html

page = requests.get("https://itunes.apple.com/in/genre/ios-business/id6000?mt=8")
tree = html.fromstring(page.text)

flist = []
plist = []
for i in range(0, 100):
    app = tree.xpath("//div[@class='column first']/ul/li/a/@href")
    ap = app[0]
    page1 = requests.get(ap)

当我尝试(0,2)的范围，它工作，但当我把范围在100，它显示这个错误:

Traceback (most recent call last):
  File "/home/preetham/Desktop/eg.py", line 17, in <module>
    page1 = requests.get(ap)
  File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 55, in get
    return request('get', url, **kwargs)

    resp = self.send(prep, **send_kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 486, in send
    r = adapter.send(request, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/adapters.py", line 378, in send
    raise ConnectionError(e)

当前回答

首先我运行run.py文件，然后我运行unit_test.py文件，它为我工作

其他回答

即使在安装pyopenssl和尝试各种python版本后，我也无法在Windows上工作(而它在mac上工作得很好)，所以我切换到urllib，它可以在python 3.6(从python .org)和3.7 (anaconda)上工作

import urllib 
from urllib.request import urlopen
html = urlopen("http://pythonscraping.com/pages/page1.html")
contents = html.read()
print(contents)

为这个请求添加报头。

headers={
'Referer': 'https://itunes.apple.com',
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36'
}

requests.get(ap, headers=headers)

加上我自己的经验:

r = requests.get(download_url)

当我试图下载url中指定的文件时。

错误在于

HTTPSConnectionPool(host, port=443): Max retries exceeded with url (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))

我通过在函数中添加verify = False来纠正它，如下所示:

r = requests.get(download_url + filename)
open(filename, 'wb').write(r.content)

PIP install pyopenssl似乎为我解决了这个问题。

我正在用Gauge编写一个测试，我也遇到了这个错误，这是因为我试图在没有激活VPN的情况下请求内部URL。
