python - 无法在 CherryPy 3.8.0 上使用 SSL

Question

我正在尝试在 CherryPy 3.8.0 上使用 SSL。我的基本示例在 SSL 上实现 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，出现错误。 Httpie、cURL 和 openssl 日志如下。

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

* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs

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

OpenSSL 日志:

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())

有效。

可能的问题:

配置无效

从配置中删除 cherrypy. 前缀:

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

当我有cherrypy前缀的配置时，我有完全相同的异常。当我修复它时，一切正常。

Python 不支持 SSL

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

证书无效

您确定您的证书正确吗？
