我有一些困难，尝试在Python中使用代理创建SSL套接字这需要认证。我是非常感谢，但我觉得最好尽可能包含更多细节。Python SSLError：客户端错误（EOF发生违反协议），服务器端错误（SSL3_GET_RECORD：错误的版本号）
首先，服务器的代码如下所示：
class ThreadedTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
def __init__(self, server_address, RequestHandlerClass, client_manager, recv_queue):
SocketServer.TCPServer.__init__(self, server_address, RequestHandlerClass, bind_and_activate=True)
<snipped out extra code>
class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):
def setup(self):
while True:
try:
print 'trying to wrap in ssl'
self.request = ssl.wrap_socket(self.request,
certfile=(os.getcwd() + '/ssl_certs/newcert.pem'),
keyfile=(os.getcwd() + '/ssl_certs/webserver.nopass.key'),
server_side=True,
cert_reqs=ssl.CERT_NONE,
ssl_version=ssl.PROTOCOL_TLSv1,
do_handshake_on_connect=False,
suppress_ragged_eofs=True)
break
except Exception, ex:
print 'error trying to wrap in ssl %s' % ex
def handle(self):
# Display message that client has connected
print '\r[*] Received connection from %s:%s\r' % (self.client_address[0], self.client_address[1])
while self.stopped() == False:
recv_msg = self.request.read(1024)
if recv_msg == '':
self.stop.set()
server.recv_queue.put(recv_msg)
break
else:
server.recv_queue.put(recv_msg)
if self.stopped():
print '[!] Received STOP signal from %s:%s; Exiting!' % (self.client_address[0], self.client_address[1])
其次，这是我设置了通过需要身份验证的代理连接所需的信息的客户端代码：
class proxyCommsHandler():
def __init__(self, user, password, remote_host, remote_port, list_of_proxies):
# information needed to connect
self.user = 'username'
self.passwd = 'password'
self.remote_host = 'remote_host_ip'
self.remote_port = 8008
self.list_of_proxies = [['proxyserver.hostname.com', 8080]]
# setup basic authentication to send to the proxy when we try to connect
self.user_pass = base64.encodestring(self.user + ':' + self.passwd)
self.proxy_authorization = 'Proxy-authorization: Basic ' + self.user_pass + '\r\n'
self.proxy_connect = 'CONNECT %s:%s HTTP/1.1\r\n' % (self.remote_host, self.remote_port)
self.user_agent = "User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:7.0.1) Gecko/20100101 Firefox/7.0.1\r\n"
self.proxy_pieces = self.proxy_connect + self.proxy_authorization + self.user_agent + '\r\n'
现在，这里是我最初连接到代理的地方，在那里我得到没有错误（我得到'200'状态码）：
self.proxy = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.proxy.connect((proxy_host, proxy_port))
self.proxy.sendall(self.proxy_pieces)
self.response = proxy.recv(1024)
这里是客户端失败的地方（我认为）。我试图把self.proxy和SSL包装它，就像这样：
sslsock = ssl.wrap_socket(self.proxy, server_side=False, do_handshake_on_connect=True,
ssl_version=ssl.PROTOCOL_TLSv1)
这是我看到的客户端上的错误：
Traceback (most recent call last):
File "C:\Python27\pyrevshell.py", line 467, in <module>
proxyCommsHandler(None, None, None, None, list_of_proxies).run()

File "C:\Python27\lib\ssl.py", line 296, in do_handshake
self._sslobj.do_handshake()
SSLError: [Errno 8] _ssl.c:503: EOF occurred in violation of protocol
客户不连接，如同自所示输出这里：
trying to wrap in ssl
[*] Received connection from x.x.x.x:47144
[*] x.x.x.x:47144 added to the client list
但后来它紧跟着的一个例外：
----------------------------------------
Exception happened during processing of request from ('x.x.x.x', 47144)
Traceback (most recent call last):

return self._sslobj.read(len)
SSLError: [Errno 1] _ssl.c:1348: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
----------------------------------------
虽然我知道这听起来像基于被抛出的异常的明显的问题，有趣的部分是：
- 我顺利地开始通过代理连接如上图所示
- 我可以在同一代理后面成功连接后面的网页浏览器，并且不会引发异常;我可以将数据传递给浏览器
- 我已经在服务器和客户端都尝试了不同的SSL协议版本，如Python documentation中的表中所示;它每次在客户端发生错误
我在连接的两端都使用了Wireshark。在使用普通浏览器并连接到服务器时，我会看到整个SSL握手和协商过程，并且一切运行顺利。但是，当我使用上面显示的客户端时，只要我连接它，我看到客户端发送一条Client Hello消息，但然后我的服务器发送一个RST数据包来终止连接（我还没有确定是否这是抛出异常之前或之后）。
再一次，我很抱歉的长度，但我急需专家的意见。
