python3.11SSL: SSLV3_ALERT_HANDSHAKE_FAILURE
参考：python request包 版本不兼容 报错sslv3 alert handshake failure 解决方法-CSDN博客
修改：Python311\Lib\site-packages\urllib3\util\ssl_.py
新版本3.11里默认没有DEFAULT_CIPHERS
补回来:
#__imported from 3.6.8
# A secure default.
# Sources for more information on TLS ciphers:

# - https://www.ssllabs.com/projects/best-practices/index.html
# - https://hynek.me/articles/hardening-your-web-servers-ssl-ciphers/
#
# The general intent is:
# - prefer cipher suites that offer perfect forward secrecy (DHE/ECDHE),
# - prefer ECDHE over DHE for better performance,
# - prefer any AES-GCM and ChaCha20 over any AES-CBC for better performance and
# security,
# - prefer AES-GCM over ChaCha20 because hardware-accelerated AES is common,
# - disable NULL authentication, MD5 MACs, DSS, and other
# insecure ciphers for security reasons.
# - NOTE: TLS 1.3 cipher suites are managed through a different interface
# not exposed by CPython (yet!) and are enabled by default if they're available.
DEFAULT_CIPHERS = ":".join(

第二处：create_urllib3_context函数里
# Unless we're given ciphers defer to either system ciphers in
# the case of OpenSSL 1.1.1+ or use our own secure default ciphers.
if ciphers:
context.set_ciphers(ciphers)
else: #added by from 3.6.8
context.set_ciphers(DEFAULT_CIPHERS)
修改这处之后，不再报握手错误，正常连接
