我设置了一个服务器,监听SSL端口。我可以连接到这个服务器,并且用正确的凭证访问服务(下面的例子是回显服务)。

下面的代码运行得很好,但我不太明白客户端在什么时刻接受证书

服务器:

import os.path
import logging
import cherrypy
from pyamf.remoting.gateway.wsgi import WSGIGateway

logging.basicConfig(
    level=logging.DEBUG,
    format='%(asctime)s %(levelname)-5.5s [%(name)s] %(message)s'
)

def auth(username, password):
    users = {"user": "pwd"}
    if (users.has_key(username) and users[username] == password):
            return True
    return False

def echo(data):
   return data

class Root(object):
    @cherrypy.expose
    def index(self):
            return "This is your main website"

gateway = WSGIGateway({'myservice.echo': echo,}, logger=logging, debug=True, authenticator=auth)

localDir = os.path.abspath(os.path.dirname(__file__))
CA = os.path.join(localDir, 'new.cert.cert')
KEY = os.path.join(localDir, 'new.cert.key')
global_conf = {'global': {'server.socket_port': 8443,
                      'environment': 'production',
                      'log.screen': True,
                      'server.ssl_certificate': CA,
                      'server.ssl_private_key': KEY}}

cherrypy.tree.graft(gateway, '/gateway/')
cherrypy.quickstart(Root(), config=global_conf)

客户端:

import logging
from pyamf.remoting.client import RemotingService

logging.basicConfig(
    level=logging.DEBUG,
    format='%(asctime)s %(levelname)-5.5s [%(name)s] %(message)s'
)

client = RemotingService('https://localhost:8443/gateway', logger=logging)
client.setCredentials('user', 'pwd')

service = client.getService('myservice')
print service.echo('Echo this')

现在,当我运行这个时,它运行得很好,客户端的日志如下:

2010-01-18 00:50:56,323 INFO  [root] Connecting to https://localhost:8443/gateway

</Envelope>
2010-01-18 00:50:56,468 DEBUG [root] Removing request: /1
Echo this

日志中的这一行2010-01-18 00:50:56,467 DEBUG [root] 读取了41字节的响应看起来有点可疑,因为响应太短了(证书大约是1K),我本来期待证书的传输会在调试日志中显示出来。

问题:客户端在什么时刻接受证书?默认情况下,它会存储在哪里?哪个配置参数设置了默认位置?

PyAMF在后台使用httplib来处理远程请求。当通过https://连接时,它会使用httplib.HTTPSConnection作为RemotingServiceconnection属性。

文档中提到(关于HTTPSConnection):

注意:这并不进行任何证书验证

所以,回答你的问题,证书基本上是被忽略的,即使你给connection提供了key_filecert_file参数。

实际上,忽略是在调用connect方法时发生的——也就是当请求真正发送到网关时……

[root] 正在向 /gateway 发送POST请求

Read 41 bytes for the response表示未加密的http响应长度。

这个回答可能没有包含你所需的所有信息,但应该能帮助你理解你所看到的行为。
