我试图使用urllib.request访问一个链接，但是它显示了这个错误

The last 30x error message was:
Found

我尝试了许多方法，但无法访问它，它正常工作时，打开铬虽然。

参考代码是-

import urllib.request

url="###"
webUrl  = urllib.request.urlopen(url)   
data = webUrl.read()        
print(data)

我试过使用cookie方法，但是它仍然不起作用：

如果可以的话，请为这个问题建议一个“不那么可疑的网站”。

python-3.x

好的，这似乎是因为302错误，它应该返回一个重定向列表，而是返回一个空列表。我认为这是一次不寻常的阻止脚本访问的尝试。您可以在会话中使用user-agent字符串模拟浏览器。我使用请求模块是因为它更容易

import requests as req

url = "###"

session = req.Session()
session.headers.update({'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36'})

r = session.get(###)
print(r.status_code)
print(r.content)

使用此脚本可以看到空302响应。

import requests as req

r = req.get(###, allow_redirects=False)
print(r.status_code)
print(r.url)
print(r.history)

使用session.close()时不要忘记关闭tcp连接。
