SSL: CERTIFICATE_VERIFY_FAILED with Python3

问题:

I apologize if this is a silly question, but I have been trying to teach myself how to use BeautifulSoup so that I can create a few projects.

I was following this link as a tutorial: https://www.youtube.com/watch?v=5GzVNi0oTxQ

After following the exact same code as him, this is the error that I get:

Traceback (most recent call last):   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 1240, in do_open     h.request(req.get_method(), req.selector, req.data, headers)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 1083, in request     self._send_request(method, url, body, headers)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 1128, in _send_request     self.endheaders(body)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 1079, in endheaders self._send_output(message_body)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 911, in _send_output     self.send(msg)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 854, in send     self.connect()   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/http/client.py", line 1237, in connect server_hostname=server_hostname)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/ssl.py", line 376, in wrap_socket _context=self)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/ssl.py", line 747, in __init__ self.do_handshake()   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/ssl.py", line 983, in do_handshake     self._sslobj.do_handshake()   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/ssl.py", line 628, in do_handshake     self._sslobj.do_handshake() ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645) 

During handling of the above exception, another exception occurred:

Traceback (most recent call last):   File "WorldCup.py", line 3, in      x = urllib.request.urlopen('https://www.google.com')   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 162, in urlopen     return opener.open(url, data, timeout)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 465, in open     response = self._open(req, data)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 483, in _open '_open', req)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 443, in _call_chain     result = func(*args)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 1283, in https_open     context=self._context, check_hostname=self._check_hostname)   File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/urllib/request.py", line 1242, in do_open raise URLError(err) urllib.error.URLError: 

Can someone help me figure out how to fix this?

回答1:

Go to the folder where Python is installed, e.g., in my case it is installed in the Applications folder with the folder name 'Python 3.6'. Now double click on 'Install Certificates.command'. After that error was gone.

回答2:

In my case, I used the ssl module to "workaround" the certification like so:

import ssl  ssl._create_default_https_context = ssl._create_unverified_context 

Then to read your link content, you can use:

urllib.request.urlopen(urllink)
