我在用

import requests
requests.post(url='https://foo.com', data={'bar':'baz'})

但我得到一个 request.exceptions.SSLError。该网站有一个过期的证书，但我没有发送敏感数据，所以对我来说没关系。我想我可以使用像“verifiy=False”这样的论点，但我似乎找不到它。

从文档中：

requests如果设置 verify为 False，也可以忽略验证 SSL 证书。

>>> requests.get('https://kennethreitz.com', verify=False)
<Response [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，requests它可以修改并更改它，使其verify=False成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

以下是你如何使用它： 

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

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

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

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

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

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

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

请注意，一旦您离开上下文管理器，此代码将关闭处理修补请求的所有打开的适配器。这是因为 requests 维护一个每个会话的连接池，并且每个连接只发生一次证书验证，所以会发生这样的意外情况：

>>> import requests
>>> session = requests.Session()
>>> session.get('https://wrong.host.badssl.com/', 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

使用requests.packages.urllib3.disable_warnings()和方法verify=False。requests

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)

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

import requests

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

请注意urllib3，（Requests 使用）强烈反对发出未经验证的 HTTPS 请求，并且会引发InsecureRequestWarning.

也可以从环境变量中完成：

export CURL_CA_BUNDLE=""

如果您想使用 verify=False 选项准确发送 post 请求，最快的方法是使用此代码：

import requests

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

如果您正在编写一个爬虫并且真的不关心 SSL 证书，您可以将其设置为全局：

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

不要在生产中使用

什么对我有用 Due verify=FalseBug

由于在设置 环境变量 ( )时session.verify=False导致urllib*忽略的错误。所以我们将其设置为空。
CURL_CA_BUNDLE

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'})

不确定我需要trust_env
