sparql - Python 3.6：[SSL：CERTIFICATE_VERIFY_FAILED] 使用 SPARQL 端点。以前没有发生

问题描述

我有一个使用库 SPARQLWrapper 从 SPARQL 获取结果的脚本。在过去的 3 个月里它一直运行良好，现在我尝试在休息一个月后再次运行它，它似乎不起作用。我收到以下错误：

Traceback (most recent call last):
  File "C:\Users\Emre\Anaconda3\lib\urllib\request.py", line 1318, in do_open
    encode_chunked=req.has_header('Transfer-encoding'))
  File "C:\Users\Emre\Anaconda3\lib\http\client.py", line 1239, in request
    self._send_request(method, url, body, headers, encode_chunked)
  File "C:\Users\Emre\Anaconda3\lib\http\client.py", line 1285, in _send_request
    self.endheaders(body, encode_chunked=encode_chunked)

    self._sslobj.do_handshake()

    self._sslobj.do_handshake()
ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)

During handling of the above exception, another exception occurred:

    results = sparql.query().convert()["results"]["bindings"]

    response = self._open(req, data)
  File "C:\Users\Emre\Anaconda3\lib\urllib\request.py", line 544, in _open
    '_open', req)

    result = func(*args)
  File "C:\Users\Emre\Anaconda3\lib\urllib\request.py", line 1361, in https_open
    context=self._context, check_hostname=self._check_hostname)
  File "C:\Users\Emre\Anaconda3\lib\urllib\request.py", line 1320, in do_open
    raise URLError(err)
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)>

我怎么可能解决这个问题？
