从文档中可以看到:

请求也可以忽略验证SSL证书 验证为False。 >>> requests.get('https://kennethreitz.com'， verify=False) <响应[200]>

如果您正在使用第三方模块并想要禁用检查，这里有一个上下文管理器，它可以猴子修补请求并更改它，以便将verify=False作为默认值并抑制警告。

import warnings
import contextlib

import requests
from urllib3.exceptions import InsecureRequestWarning

old_merge_environment_settings = requests.Session.merge_environment_settings

@contextlib.contextmanager
def no_ssl_verification():
    opened_adapters = set()

    def merge_environment_settings(self, url, proxies, stream, verify, cert):
        # Verification happens only once per connection so we need to close
        # all the opened adapters once we're done. Otherwise, the effects of
        # verify=False persist beyond the end of this context manager.
        opened_adapters.add(self.get_adapter(url))

        settings = old_merge_environment_settings(self, url, proxies, stream, verify, cert)
        settings['verify'] = False

        return settings

    requests.Session.merge_environment_settings = merge_environment_settings

    try:
        with warnings.catch_warnings():
            warnings.simplefilter('ignore', InsecureRequestWarning)
            yield
    finally:
        requests.Session.merge_environment_settings = old_merge_environment_settings

        for adapter in opened_adapters:
            try:
                adapter.close()
            except:
                pass

下面是如何使用它:

with no_ssl_verification():
    requests.get('https://wrong.host.badssl.example/')
    print('It works')

    requests.get('https://wrong.host.badssl.example/', verify=True)
    print('Even if you try to force it to')

requests.get('https://wrong.host.badssl.example/', verify=False)
print('It resets back')

session = requests.Session()
session.verify = True

with no_ssl_verification():
    session.get('https://wrong.host.badssl.example/', verify=True)
    print('Works even here')

try:
    requests.get('https://wrong.host.badssl.example/')
except requests.exceptions.SSLError:
    print('It breaks')

try:
    session.get('https://wrong.host.badssl.example/')
except requests.exceptions.SSLError:
    print('It breaks here again')

注意，一旦离开上下文管理器，此代码将关闭所有处理修补过的请求的打开适配器。这是因为请求维护每个会话的连接池，证书验证只发生一次每个连接，所以会发生意想不到的事情:

>>> import requests
>>> session = requests.Session()
>>> session.get('https://wrong.host.badssl.example/', verify=False)
/usr/local/lib/python3.7/site-packages/urllib3/connectionpool.py:857: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecureRequestWarning)
<Response [200]>
>>> session.get('https://wrong.host.badssl.example/', verify=True)
/usr/local/lib/python3.7/site-packages/urllib3/connectionpool.py:857: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecureRequestWarning)
<Response [200]>

在请求方法上使用requests.packages.urllib3.disable_warnings()和verify=False。

import requests
from urllib3.exceptions import InsecureRequestWarning

# Suppress only the single warning from urllib3 needed.
requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)

# Set `verify=False` on `requests.post`.
requests.post(url='https://example.com', data={'bar':'baz'}, verify=False)

如果你想准确地发送带有verify=False选项的post请求，最快的方法是使用以下代码:

import requests

requests.api.request('post', url, data={'bar':'baz'}, json=None, verify=False)

要添加到Blender的答案中，您可以使用Session禁用所有请求的SSL证书验证。verify = False

import requests

session = requests.Session()
session.verify = False
session.post(url='https://example.com', data={'bar':'baz'})

请注意urllib3(请求使用的)强烈不鼓励发出未经验证的HTTPS请求，并将引发InsecureRequestWarning。

也可以使用环境变量:

export CURL_CA_BUNDLE=""

如果你正在编写一个scraper并且真的不关心SSL证书，你可以将其设置为全局:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

不用于生产

编辑，评论来自@Misty

不工作。Requests现在使用urllib3，它创建自己的urllib3 SSLContext。您可以重写cert_reqs

ssl.SSLContext.verify_mode = property(lambda self: ssl.CERT_NONE, lambda self, newval: None)

什么对我有效Due verify=False Bug

由于会话上的错误。验证=False，使urllib*忽略 当设置环境变量(CURL_CA_BUNDLE)时。所以我们把它设为零。

import requests, os
session = requests.Session()
session.verify = False
session.trust_env = False
os.environ['CURL_CA_BUNDLE']="" # or whaever other is interfering with 
session.post(url='https://example.com', data={'bar':'baz'})

不确定我是否需要trust_env

首先导入SSL，然后在python脚本文件中用三行代码创建一个这样的变量-

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

我用beautifulsoup在html解析中使用的一个例子是这样的-

import urllib.request,urllib.parse,urllib.error

from bs4 import BeautifulSoup
import ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE


url = input('Enter - ')
html = urllib.request.urlopen(url, context=ctx).read()
soup = BeautifulSoup(html, 'html.parser')

python 3 + 6。

import warnings
warnings.filterwarnings("ignore", message="Unverified HTTPS request")
