我得到以下错误:

Exception in thread Thread-3:

raise URLError(err)
URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>

下面是导致这个错误的代码:

if input.startswith("!web"):
    input = input.replace("!web ", "")      
    url = "https://domainsearch.p.mashape.com/index.php?name=" + input
    req = urllib2.Request(url, headers={ 'X-Mashape-Key': 'XXXXXXXXXXXXXXXXXXXX' })
    info = urllib2.urlopen(req).read()
    Message.Chat.SendMessage ("" + info)

我正在使用的API要求我使用HTTPS。我怎样才能让它绕过验证呢?


当前回答

import requests
requests.packages.urllib3.disable_warnings()

import ssl

try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
    # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context

安装nltk的步骤(我已经在MAC OS X中安装了python3 (3.6.2)

sudo easy_install pip

使用ignore installed选项忽略卸载之前版本的6,否则,它会在卸载时给出一个错误,并且不进行电影转发

sudo pip3 install -U nltk --ignore-installed six

检查pip和python的安装,使用'3'版本

which python python2 python3
which pip pip2 pip3

检查NLTK是否安装

python3
import nltk
nltk.__path__
['/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/nltk']

在安装示例之前安装SSL证书,否则我们将在安装示例时证书错误

/Applications/Python\ 3.6/Install\ Certificates.command
python3 -m nltk.downloader book

这就成功地完成了nltk和nltk_ata的安装

这不是您特定问题的解决方案,但我把它放在这里是因为这个线程是“SSL: CERTIFICATE_VERIFY_FAILED”的顶部谷歌结果,它导致我在一个徒劳的追逐。

If you have installed Python 3.6 on OSX and are getting the "SSL: CERTIFICATE_VERIFY_FAILED" error when trying to connect to an https:// site, it's probably because Python 3.6 on OSX has no certificates at all, and can't validate any SSL connections. This is a change for 3.6 on OSX, and requires a post-install step, which installs the certifi package of certificates. This is documented in the file ReadMe.rtf, which you can find at /Applications/Python\ 3.6/ReadMe.rtf (see also the file Conclusion.rtf, and the script build-installer.py that generates the macOS installer).

ReadMe会让你运行安装后的脚本

/Applications/Python\ 3.10/Install\ Certificates.command(终端应用程序,这个命令应该单独解决问题。请确保使用当前的subversion更新文件路径。)

(它的源是install_certificates.command),其中:

首先安装Python包certifi,然后 然后创建一个从OpenSSL证书文件到包certificate安装的证书文件的符号链接。

在较新的Python版本中,有更多关于此的文档:

我在Python 2.7.9中遇到了这个问题

以下是我所做的:

卸载Python 2.7.9 删除c:\Python27文件夹 下载了Python 2.7.18,这是今天最新发布的Python 2.7。 重新运行应用程序 它成功了!

不再有任何“[CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)”错误。

在我的情况下,我得到这个错误,因为请求和urllib3版本不兼容,在安装期间给出以下错误:

ERROR: requests 2.21.0 has requirement urllib3<1.25,>=1.21.1, but you'll have urllib3 1.25 which is incompatible.
pip install 'urllib3<1.25' --force-reinstall

成功了。

我很惊讶所有这些指导都没有解决我的问题。尽管如此,诊断是正确的(顺便说一句,我使用Mac和Python3.6.1)。所以,总结一下正确的部分:

在Mac上,苹果放弃了OpenSSL Python现在使用它自己的CA根证书集 二进制Python安装提供了一个脚本来安装Python所需的CA根证书("/Applications/Python 3.6/ install Certificates.command") 详细信息请阅读“/Applications/Python 3.6/ReadMe.rtf”

对我来说,脚本不能工作,所有那些证书和openssl安装也未能修复。也许是因为我安装了多个python2和python3,以及许多virtualenv。最后,我需要手工修理它。

pip install certifi   # for your virtualenv
mkdir -p /Library/Frameworks/Python.framework/Versions/3.6/etc/openssl
cp -a <your virtualenv>/site-package/certifi/cacert.pem \
  /Library/Frameworks/Python.framework/Versions/3.6/etc/openssl/cert.pem

如果你还不满意的话。然后重新安装OpenSSL。

port install openssl
