无法在CherryPy 3.8.0上使用SSL

Question

我试图在CherryPy 3.8.0上使用SSL。 我的基本示例在SSL上实现了ping响应。

我以这种方式设置SSL的配置：

# start Web Service with some configuration
global_conf = {
       "global":    { "server.environment": "production",
                      "engine.autoreload.on": True,
                      "engine.autoreload.frequency": 5,
                      "server.socket_host": "0.0.0.0",
                      "server.socket_port": 443,
                      "cherrypy.server.ssl_module": "builtin",
                      "cherrypy.server.ssl_certificate": "cert.pem",
                      "cherrypy.server.ssl_private_key": "privkey.pem",
                      "environment": "production",
                      "log.error_file": "site.log"}
}
cherrypy.config.update(global_conf)
conf = {
    "/": {
        "request.dispatch": cherrypy.dispatch.MethodDispatcher(),
        "tools.encode.debug": True,
    }
}

但是，当我调用Web服务时，会出现错误。 随后是Httpie，cURL和openssl日志。

Httpie日志：

> http GET https://<host>:443/ping
http: error: SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:600)

cURL日志：

> curl -v https://<host>:443/ping
* Connected to <host> (<host>) port 443 (#0)
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):

* Closing connection 0
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

OpenSSL日志：

> openssl s_client -host <host> -port 443

140197694400160:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:795:

Answer 1

简单的例子：

import cherrypy

class RootServer:
    @cherrypy.expose
    def index(self, **keywords):
        return "it works!"

if __name__ == '__main__':
    server_config={
        'server.socket_host': '0.0.0.0',
        'server.socket_port':443,
        'server.ssl_module':'builtin',
        'server.ssl_certificate':'cert.pem',
        'server.ssl_private_key':'privkey.pem'
    }

    cherrypy.config.update(server_config)
    cherrypy.quickstart(RootServer())

作品。

可能的问题：

无效的配置

删除cherrypy. 来自配置的前缀：

"server.ssl_module": "builtin",
"server.ssl_certificate": "cert.pem",
"server.ssl_private_key": "privkey.pem",

当我使用cherrypy前缀的配置时，我有完全相同的例外。 修复后，一切正常。

Python不支持SSL

尝试安装pyOpenSSL并将server.ssl_module替换为pyopenssl 。

无效的证书

您确定您的证书正确吗？

查看http://docs.cherrypy.org/en/latest/deploy.html#ssl-support

Answer 2

据我所知，CherryPy的不同版本中存在一些SSL问题。 问题之一： 在SSLAdapter中添加对客户端证书验证的支持（包括补丁）
