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

如果证书是通过Let's encrypt颁发的,请确保在客户机上的中间证书存储中删除过期的DST根CA X3颁发的R3证书。

其他回答

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。

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

Python 2.7.12(默认,2016年7月29日,15:26:22)修复了上述问题。这个信息可能会帮助到其他人。

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。

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!
