python客户端无法将密钥文件传递给wrap_socket（）

我有一个用C编写的SSL套接字服务器，托管在运行RHEL的AWS实例上。服务器目前正在使用自签名证书，我正在尝试连接python客户端。当我尝试指定要使用的公钥时，出现以下错误：

TypeError: wrap_socket() got an unexpected keyword argument 'keyfile'

最简单的客户端代码是：

#!/bin/python

import socket
import ssl
#Host is the public domain name of an AWS instance
HOST = "some.host.amazonaws.com"
#Create context
con = ssl.create_default_context()
#Wrap socket with ssl context
soc = con.wrap_socket(socket.socket(socket.AF_INET), keyfile="pubkey.pem", server_hostname = HOST)
#connect to host
soc.connect((HOST, 8615))
#Get and print the host cert
cert = soc.getpeercert()
pprint.pprint(cert)

在python文档中，它说我可以指定keyfile/certfile，所以我不明白为什么会失败

如果我删除keyfile=pubkey.pem，则它无法验证证书：

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)

我不相信它是服务器，因为我运行了s_client并获得以下输出：

CONNECTED(00000003)

似乎客户端证书未发送到服务器。在创建缺少的连接时，是否有方法指定公钥

非常感谢您的帮助

TypeError:wrap_套接字获得意外的关键字参数“keyfile”

调用context.wrap\u套接字时没有keyfile参数。。。。调用ssl.wrap_套接字时有一个keyfile参数。。。。这样做的原因是，当ssl.wrap_socket。。。创建一个新的上下文

有关更多详细信息，请参阅vs..

非常感谢您的帮助。我还必须调用load\u verify\u locations/path/to/root/rootCA.pem，因为它在加载\u default\u证书时失败，即使它安装在keychain macOS中也不知道为什么，但它现在可以工作了！再次感谢：@PSD:Python没有使用MacOSX的钥匙链。
