我正在练习'Web Scraping with Python'的代码,我一直有这个证书问题:
from urllib.request import urlopen
from bs4 import BeautifulSoup
import re
pages = set()
def getLinks(pageUrl):
global pages
html = urlopen("http://en.wikipedia.org"+pageUrl)
bsObj = BeautifulSoup(html)
for link in bsObj.findAll("a", href=re.compile("^(/wiki/)")):
if 'href' in link.attrs:
if link.attrs['href'] not in pages:
#We have encountered a new page
newPage = link.attrs['href']
print(newPage)
pages.add(newPage)
getLinks(newPage)
getLinks("")

错误是:
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py", line 1319, in do_open
raise URLError(err)
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1049)>

顺便说一句,我也在练习scrapy,但一直都在解决问题:找不到命令:scrapy(我在网上尝试过各种解决方案,但都没有用......真的很令人沮丧)
我正在尝试使用python从网络获取数据。我为此导入了urllib.request包,但是在执行时出现错误:
certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)

当我将网址更改为“ http”时-我可以获取数据。但是,我相信,这避免了检查SSL证书。
所以我检查了互联网,找到了一个解决方案:运行 /Applications/Python\ 3.7/Install\ Certificates.command
这解决了我的问题。但是我对SSL之类的东西一无所知。您能否帮助我了解它实际上解决了我的问题。
如果可能,请向我推荐任何有用的资源,以了解有关安全性和证书的信息。我是新来的。
谢谢!
注意:我确实通过链接-openssl,python请求错误:“证书验证失败”
我的问题与链接中的问题不同,因为我想知道在安装certifi软件包或运行Install\ Certificates.command该错误时实际发生了什么。我对证券知之甚少。
我正在使用 Pycharm 和 python 3.8 以及最新版本的不和谐。我尝试运行此脚本但出现此错误。任何人都可以帮忙吗?
