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

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。

对于Centos 6/7、Fedora上的Python 3.4+,只需按如下方式安装受信任CA:

拷贝CA.crt到/etc/pki/ca-trust/source/anchors/ update-ca-trust force-enable update-ca-trust提取

我也遇到了类似的问题,不过我在Python 3.4、3.5和3.6中使用了urllib.request.urlopen。(这是Python 3中urllib2的一部分,根据Python 2的urllib2文档页面头部的注释。)

我的解决方案是pip install certifi来安装certifi,它有:

... 一个精心策划的根证书集合,用于验证SSL证书的可信度,同时验证TLS主机的身份。

然后,在我的代码中,我之前只有:

import urllib.request as urlrq

resp = urlrq.urlopen('https://example.com/bar/baz.html')

我将其修改为:

import urllib.request as urlrq
import certifi

resp = urlrq.urlopen('https://example.com/bar/baz.html', cafile=certifi.where())

如果我读取urllib2。Urlopen文档正确,它也有一个cafile参数。所以,urllib2.urlopen([…], certificate .where())可能也适用于Python 2.7。


更新(2020-01-01):自Python 3.6起,已弃用urlopen的cafile参数,取而代之的应该是指定context参数。我发现以下功能在3.5到3.8版本中同样有效:

import urllib.request as urlrq
import certifi
import ssl

resp = urlrq.urlopen('https://example.com/bar/baz.html', context=ssl.create_default_context(cafile=certifi.where()))

如果你有私人证书要处理,比如你的组织自己的CA根和链的中间部分,那么最好将证书添加到CA文件中,即cacert。pem,而不是绕过整个安全设备(verify=False)。下面的代码让你在2.7+和3+

考虑添加整个证书链,当然您只需要这样做一次。

import certifi

cafile=certifi.where() # cacert file
with open ('rootca.pem','rb') as infile:
    customca=infile.read()
    with open(cafile,'ab') as outfile:
        outfile.write(customca)
with open ('interca.pem','rb') as infile:
    customca=infile.read()
    with open(cafile,'ab') as outfile:
        outfile.write(customca)
with open ('issueca.pem','rb') as infile:
    customca=infile.read()
    with open(cafile,'ab') as outfile:
        outfile.write(customca)

那这个应该能让你振作起来

import requests
response = requests.request("GET", 'https://yoursecuresite.com',  data = {})
print(response.text.encode('utf8'))

希望这能有所帮助

我在这里找到了这个

我找到了这个解决方案,在你的源文件开始插入这段代码:

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

这段代码将撤销验证,这样就不会验证ssl证书。
