“SSL: CERTIFICATE_VERIFY_FAILED”错误

我得到以下错误:

Exception in thread Thread-3:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 810, in        __bootstrap_inner

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

在Mac上安装证书解决了我的问题:

pip install certifi

其他回答

Try

PIP install——trusted.host pypi.python.org packagename

这对我很管用。

您可以使用以下命令在python中安装包

在木星笔记本上

!pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org --user [Pacakage name]

!pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org --user xgboost

请注意，我已经尝试在mac和windows中安装证书

I was getting the same error, and also went on a wild goose chase for quite a while before I gave up and started trying things on my own. I eventually figured it out, so I thought I'd share. In my case, I am running Python 2.7.10 (due to reasons beyond my control) on Linux, don't have access to the requests module, can't install certificates globally at the OS or Python level, can't set any environment variables, and need to access a specific internal site that uses internally issued certificates.

注意:禁用SSL验证从来不是一个选项。我正在下载一个脚本，它可以立即以根用户的身份运行。没有SSL验证，任何web服务器都可以假装是我的目标主机，而我只是接受他们给我的任何东西，并以root身份运行它!

我将根证书和中间证书(可能不止一个)以pem格式保存到一个文件中，然后使用以下代码:

import ssl,urllib2
data = urllib2.build_opener(urllib2.HTTPSHandler(context=ssl.create_default_context(cafile='/path/to/ca-cert-chain.pem')), urllib2.ProxyHandler({})).open('https://your-site.com/somefile').read()
print(data)

注意，我在那里添加了urllib2.ProxyHandler({})。这是因为在我们的环境中，代理是默认设置的，但它们只能访问外部站点，不能访问内部站点。如果没有代理绕过，我就无法访问内部站点。如果你没有这个问题，你可以简化如下:

data = urllib2.build_opener(urllib2.HTTPSHandler(context=ssl.create_default_context(cafile='/path/to/ca-cert-chain.pem'))).open('https://your-site.com/somefile').read()

工作起来很有魅力，而且不会危及安全。

享受吧!

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。
