我正在尝试阅读和解析网站内容。我正在使用Python 3.5.2但我已经完成了300.000条目。在某些时候，我有两个错误;
1.TimeoutError: [WinError 10060]
2. AttributeError: type object 'URLError' has no attribute 'reason'
我搜索过这些错误并尝试了一些解决方案。但是，我仍然得到它们。我不知道如何解决第一个错误。对于第二个错误，它告诉我URLError中没有属性“reason”。但我也试过“代码”属性。除此之外，当我控制网页时，网页就存在了，为什么我会收到这些错误。如何解决其中两个错误？

我的代码如下;
import requests

from urllib.request import urlopen # the lib that handles the url stuff
import urllib.request, urllib.error, urllib.parse
import ssl
import sys
from socket import timeout
def read_url_content(pdb):
pdbObj = None
try:
context = ssl._create_unverified_context()
data = list(urlopen("https://files.rcsb.org/view/"+pdb+".pdb", context = context ,timeout=60)) # it's a file like object and works just like a file
pdbObj = PDB(pdb)
except urllib.error.URLError as e:
print("Error in pdb no chain added. Obj is empty.", pdb)
ResponseData = e.reason
e = sys.exc_info()[0]
print(e)
print(e.reason)
pass
except timeout:
logging.error('socket timed out - URL %s', pdb)
return pdbObj
