我需要在运行时连接到我的twisted应用程序,我正试图让twisted.manhole为我工作。我在MacOSX10.6上,默认安装Twisted8.2。在
sample server using twistd起作用了。在启动时有关于md5、sha和twisted.protocols.telnet公司,但检修孔服务器实际上做了它应该做的,我可以访问应用程序的内部:
host:client user$ telnet localhost 4040
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
twisted.manhole.telnet.ShellFactory
Twisted 8.2.0
username: admin
password: *****
>>> dir()
['_', '__builtins__', 'factory', 'service']
>>> factory
<twisted.manhole.telnet.ShellFactory instance at 0x101256440>
>>> service
<twisted.application.internet.TCPServer instance at 0x10124ff38>
>>> service.parent
<twisted.application.service.MultiService instance at 0x1014b0cf8>
>>>
现在,我尝试将其集成到我的应用程序中:
^{pr2}$在shell中运行上述代码:
host:server user$ twistd -noy test_manhole.tac
(omitting the same DeprecationWarnings about md5, sha and twisted.protocols.telnet as earlier)
2011-08-24 16:52:13+1000 [-] Log opened.
2011-08-24 16:52:13+1000 [-] twistd 8.2.0 (/usr/bin/python2.6 2.6.1) starting up.
2011-08-24 16:52:13+1000 [-] reactor class: twisted.internet.selectreactor.SelectReactor.
2011-08-24 16:52:13+1000 [-] twisted.manhole.telnet.ShellFactory starting on 4040
2011-08-24 16:52:13+1000 [-] Starting factory <twisted.manhole.telnet.ShellFactory instance at 0x1012cfdd0>
2011-08-24 16:52:13+1000 [-] start service: <twisted.application.internet.TCPServer instance at 0x1012cff80>
在第二个shell中,运行telnet客户端:
host:client user$ telnet localhost 4040
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
twisted.manhole.telnet.ShellFactory
Twisted 8.2.0
username: admin
password: *****
>>> dir()
['_', '__builtins__', 'factory', 'service', 'some_value']
>>> factory
<twisted.manhole.telnet.ShellFactory instance at 0x1012cfdd0>
>>> service
>>> service == None
True
>>> service.parent
...
exceptions.AttributeError: 'NoneType' object has no attribute 'parent'
>>> some_value
42
因此,服务对象似乎不可用于访问应用程序内部。在
好的,既然twisted.protocols.telnet
似乎已经被twisted.conch.telnet
取代,请尝试使用更新的模块:
# test_manhole_2.tac
from twisted.application.service import Application, IServiceCollection
from twisted.conch.manhole_tap import makeService
options = \
{
# for some reason, these must
# all exist, even if None
'namespace' : None,
'passwd' : 'users.txt',
'sshPort' : None,
'telnetPort' : '4040',
}
shell_service = makeService(options)
application = Application('test')
serviceCollection = IServiceCollection(application)
shell_service.setServiceParent(serviceCollection)
“密码文件”users.txt
可能只包含一行示例用户名和密码,例如admin:admin
。在
启动测试服务器:
host:server user$ twistd -noy test_manhole_2.tac
(omitting DeprecationWarnings about md5 and sha)

在第二个shell中,运行telnet客户端-请注意,其中一些实际上是猜测,因为有缺陷的Mac OSX readline(或其他原因)似乎吞下了一些shell输出:
host:client user$ telnet localhost 4040
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Username: admin

>>> dir()
['__builtins__']
所以现在看来我已经从一个无用的service
对象变成了根本没有对象。在
怎么样扭曲人孔正确使用?在
继续使用
