Python 2.7 在python上下载文件会被禁止使用http 403

我一直在尝试使用Python 2.7从链接下载一个文件，但它一直在说：

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)>

---

我推荐

请求

和

假用户代理

首先，确保已使用命令行安装它们：

pip install requests fake-useragent

然后使用：

import requests
from fake_useragent import UserAgent

ua_str = UserAgent().chrome
url = "https://www.py4e.com/code3/mbox.txt"
r = requests.get(url, headers={"User-Agent": ua_str})
txt = r.content

---

这是另一种简单的方法

代码：

import urllib2
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}

req = urllib2.Request("http://www.py4e.com/code3/mbox.txt", headers=hdr)
page = urllib2.urlopen(req)
content = page.read()
print content

样本输出：

希望能有帮助

看看这个：您基本上需要将用户代理设置为浏览器。web服务器的安全设置通常是bot
