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

Amazon EC2上的Python 2.7,附带centOS 7

我必须设置env变量SSL_CERT_DIR指向我的ca-bundle,它位于/etc/ssl/certs/ca-bundle.crt

其他回答

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:

你可以试着把这个添加到你的环境变量中:

PYTHONHTTPSVERIFY=0 

请注意,这将禁用所有HTTPS验证,所以这是一个大锤式的方法,但如果不需要验证,这可能是一个有效的解决方案。

这里已经有很多答案了,但我们在一个非常具体的案例中遇到了这个问题,花了很多时间调查,所以再加一个。我们在下面的例子中看到:

在一个德比安式细长的码头集装箱里 默认Python 3.5.3 easy_install3 对于在Kubernetes集群中使用cert-manager注册的LetsEncrypt证书

pip3和openssl命令行都能够验证该证书,easy_install3能够成功验证其他LetsEncrypt证书。

解决办法是从源代码构建最新的Python(当时是3.7.3)。这里的说明很详细,很容易理解。

我对Mac OS X的解决方案:

使用从Python语言官方网站https://www.python.org/downloads/下载的本地应用程序Python安装程序升级到Python 3.6.5

我发现这个安装程序在更新新Python的链接和符号链接方面比自制的要好得多。

使用"安装新证书。/Install Certificates.command”,该命令位于刷新后的Python 3.6目录中

cd "/Applications/Python 3.6/"
sudo "./Install Certificates.command"

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。
