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)

如果您使用的是第三方模块，并且想禁用检查功能，则可以使用上下文管理器来修补requests和更改它，从而使它verify=False成为默认设置并禁止显示警告。
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
使用方法如下：
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，此代码将关闭处理已打补丁请求的所有打开的适配器。这是因为请求维护了每个会话的连接池，并且证书验证每个连接仅执行一次，因此将发生以下意外情况：
>>> import requests
>>> session = requests.Session()
>>> session.get('https://wrong.host.badssl.com/', verify=False)
