我有以下 https 客户端，它尝试将简单的 POST 请求发送到删除服务器。

!/usr/bin/python3

import http.client
import json
import ssl

context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)

connection = http.client.HTTPSConnection('192.168.11.1', 444, context = context)

headers = {'Content-type': 'application/json',
           'Accept': 'application/json',
           'Content-Length': '0'}

foo = {'ver': '111'}
json_foo = json.dumps(foo)

connection.request('POST', '/post', json_foo, headers)

response = connection.getresponse()

print(response.read().decode())

但是，当我这样做时，我[SSL: WRONG_VERSION_NUMBER] wrong version number尝试将 ssl 协议手动设置为较新的版本（通过在创建连接时使用 ssl.SSLContext）。

这是调用堆栈：

  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/http/client.py", line 1245, in request
    self._send_request(method, url, body, headers, encode_chunked)
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/http/client.py", line 1291, in _send_request
    self.endheaders(body, encode_chunked=encode_chunked)
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/http/client.py", line 1240, in endheaders
    self._send_output(message_body, encode_chunked=encode_chunked)
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/http/client.py", line 1008, in _send_output
    self.send(msg)
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/http/client.py", line 948, in send
    self.connect()
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/http/client.py", line 1414, in connect
    self.sock = self._context.wrap_socket(self.sock,
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/ssl.py", line 500, in wrap_socket
    return self.sslsocket_class._create(
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/ssl.py", line 1040, in _create
    self.do_handshake()
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/ssl.py", line 1309, in do_handshake
    self._sslobj.do_handshake()
ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1108)

但是，在 python3 中，这是我拥有的选项。不幸的是，协议 2 和 3 不在列表中。

PROTOCOL_SSLv23     
PROTOCOL_TLS_SERVER 
PROTOCOL_TLSv1_2
PROTOCOL_TLS        
PROTOCOL_TLSv1
PROTOCOL_TLS_CLIENT 
PROTOCOL_TLSv1_1

知道如何在 http 连接中升级套接字的 ssl 版本吗？我需要升级 ssl 包吗？我认为它在python3（3.8.2）中相对更新

谢谢 ！

...当我使用时它起作用了... curl ...“http://192.168.11.1:444/post”

您使用 curl 成功执行的操作是一个普通的 HTTP 请求（http://...not https://...）。您正在尝试（和失败）的代码是 HTTPS 请求，即 HTTP over TLS。错误消息是尝试对不支持 TLS 的服务器使用 TLS 的结果。
