当我尝试使用wikipedia api时，我会收到一条证书错误消息。
这是针对助手的，我正在学校计算机上编码，我认为这是由行政管理部门放在那里的，因为我先前使用NPM时会出现证书错误。
这是我正在使用的代码：
wikiSearch = query.strip("wiki ")
outputs = wikipedia.summary(wikiSearch, sentences=3)
我认为这会像Python 2.7中一样返回文章的前三个句子，但返回此冗长的错误消息：

我现在得到此错误：

正如您提到的那样，您在使用NPM时遇到了类似的错误，这很可能是由于您的管理的代理设置。
您可以配置任何第三方模块连接到Internet的代理。默认情况下，URLLIB3的urlopen使用环境变量http_proxy来确定要使用哪个HTTP代理。
在运行Python应用程序之前，请在CMD中运行此命令
export http_proxy='http://myproxy.proxy.com:1234'
=======================================================================
如果您不知道代理，则可以尝试使用此解决方法。在运行Python应用程序之前，请在CMD中运行此命令
export CURL_CA_BUNDLE=''
或将这些行添加到您的代码中，以避免每次手动添加环境变量。
import os
os.environ['CURL_CA_BUNDLE'] = ""
如果您要遇到不安全Questwarning，并且想抑制它，则可以做以下内容。
import wikipedia
import os
import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
os.environ['CURL_CA_BUNDLE'] = ""
os.environ['PYTHONWARNINGS']="ignore:Unverified HTTPS request"
print(wikipedia.wikipedia.summary("Google"))
我希望这会有所帮助。
