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

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。

其他回答

我有点羞愧地低下头,因为我也遇到了同样的问题,只不过在我的情况下,我点击的URL是有效的,证书是有效的。无效的是我的网络连接。我未能将代理详细信息添加到浏览器(在这种情况下是IE)。这阻止了验证过程的正确进行。 添加了代理细节,我的python非常高兴。

我需要补充另一个答案,因为就像Craig Glennie一样,由于网上有许多提到这个问题的帖子,我进行了一次徒劳的追逐。

我正在使用MacPorts,我最初认为的Python问题实际上是MacPorts问题:它在安装openssl时没有安装根证书。解决方案是移植安装curl-ca-bundle,如本文所述。

我认为你有几种方法可以解决这个问题。我提到了以下5种方法:

你可以为每个请求定义上下文,并在每个请求上传递上下文,如下所示:

import certifi
import ssl
import urllib
context = ssl.create_default_context(cafile=certifi.where())
result = urllib.request.urlopen('https://www.example.com', context=context)

或在环境中设置证书文件。

import os
import certifi
import urllib
os.environ["REQUESTS_CA_BUNDLE"] = certifi.where()
os.environ["SSL_CERT_FILE"] = certifi.where()
result = urllib.request.urlopen('https://www.example.com')

创建默认的https上下文方法:

import certifi
import ssl
ssl._create_default_https_context = lambda: ssl.create_default_context(cafile=certifi.where())
result = urllib.request.urlopen('https://www.example.com')

如果您使用Linux机器,生成新的证书并导出指向证书目录的环境变量,则可以修复该问题。

$ sudo update-ca-certificates --fresh
$ export SSL_CERT_DIR=/etc/ssl/certs

或如果您使用Mac机器,生成新的证书

$ cd "/Applications/$(python3 --version | awk '{print $2}'| awk  -F. '{print "Python " $1"."$2}')"
$ sudo "./Install Certificates.command"

在Windows上,Python不会查看系统证书,它使用自己的位于?\lib\site-packages\certifi\cacert.pem的证书。

问题的解决方案:

下载“*”格式的域验证证书。CRT或*pem文件 在编辑器中打开文件并将其内容复制到剪贴板 找到你的cacert。Pem位置:来自请求。导入DEFAULT_CA_BUNDLE_PATH;打印(DEFAULT_CA_BUNDLE_PATH) 编辑cacert。Pem文件,并将您的域验证证书粘贴在文件的末尾。 保存文件并享受请求!

在python 2.7中,在文件C:\Python27\lib\site-packages\certifi\cacert中添加受信任根CA的详细信息。pem帮助

之后我运行(使用管理员权限) pip install——truste- host pypi.python.org——truste- host pypi.org——truste- host files.pythonhosted.org packageName
