pywebsocket 不起作用

Question

这就是我安装mod_pywebsocket作为apache扩展的方式

root@senior:/var/www# wget http://pywebsocket.googlecode.com/files/mod_pywebsocket-0.7.8.tar.gz
root@senior:/var/www# tar xvf mod_pywebsocket-0.7.8.tar.gz
root@senior:/var/www# cd pywebsocket-0.7.8/src/
root@senior:/var/www/pywebsocket-0.7.8/src# py:/./setpuup.py build
running build
running build_py
root@senior:/var/www/pywebsocket-0.7.8/src# python ./setup.py install
running install
running build
running build_py
running install_lib
running install_egg_info
Removing /usr/local/lib/python2.6/dist-packages/mod_pywebsocket-0.7.8.egg-info
Writing /usr/local/lib/python2.6/dist-packages/mod_pywebsocket-0.7.8.egg-info    
root@senior:/var/www/pywebsocket-0.7.8/src# mkdir /var/www/_wsh/
root@senior:/var/www/pywebsocket-0.7.8/src# cp example/* /var/www/_wsh/
root@senior:/var/www/pywebsocket-0.7.8/src# cd /var/www/_wsh/
root@senior:/var/www/_wsh# chmod a+x *.py
root@senior:/usr/local/lib/python2.6/dist-packages/mod_pywebsocket# cd /usr/local/lib/python2.6/dist-packages/mod_pywebsocket
root@senior:/usr/local/lib/python2.6/dist-packages/mod_pywebsocket# chmod a+rx *.py

这是我插入 httpd.conf 中的文本

<IfModule python_module>
  PythonPath "sys.path+['/usr/local/lib/python2.6/dist-packages']"
  PythonOption mod_pywebsocket.handler_root /var/www/_wsh/
  PythonOption mod_pywebsocket.handler_scan /var/www/_wsh/
  #PythonOption mod_pywebsocket.allow_draft75 On
  #<Location /var/www/_vsh>
  #  PythonHeaderParserHandler mod_pywebsocket.headerparserhandler
  #</Location>
</IfModule>

重新启动后，我正在尝试从 pywebsocket 目录示例中console.html代码（复制到/var/www/_wsh 中）。但是它不起作用，我无法打开连接。

当我尝试运行示例时，我得到了这个

root@senior:/usr# /var/www/_wsh/echo_client.py
Traceback (most recent call last):
  File "/var/www/_wsh/echo_client.py", line 995, in <module>
    main()
  File "/var/www/_wsh/echo_client.py", line 991, in main
    EchoClient(options).run()
  File "/var/www/_wsh/echo_client.py", line 840, in run
    self._handshake.handshake()
  File "/var/www/_wsh/echo_client.py", line 385, in handshake
    'Expected HTTP status code 101 but found %r' % status_code)
__main__.ClientHandshakeError: Expected HTTP status code 101 but found '200'

你能帮我找出问题出在哪里吗？谢谢

将其作为独立服务器运行要容易得多。你试过吗？

"""Standalone WebSocket server.
Use this file to launch pywebsocket without Apache HTTP Server.

BASIC USAGE
Go to the src directory and run
  $ python mod_pywebsocket/standalone.py [-p <ws_port>]
                                         [-w <websock_handlers>]
                                         [-d <document_root>]
<ws_port> is the port number to use for ws:// connection.
<document_root> is the path to the root directory of HTML files.
<websock_handlers> is the path to the root directory of WebSocket handlers.
If not specified, <document_root> will be used. See __init__.py (or
run $ pydoc mod_pywebsocket) for how to write WebSocket handlers.
For more detail and other options, run
  $ python mod_pywebsocket/standalone.py --help
or see _build_option_parser method below.
For trouble shooting, adding "--log_level debug" might help you.

在阅读了许多有关如何设置pywebsockets的教程后，我最终得到了这个配置：

LogLevel debug
<IfModule python_module>
  Timeout 0
  #This is path where I have copied pywebsocket
  PythonPath "sys.path+['/usr/local/lib/python2.6/dist-packages']"
  #This is path where I have my websocket connection handlers (files that responds to requests, I have there example files copied too)
  PythonOption mod_pywebsocket.handler_root /var/www/websockets/
  PythonOption mod_pywebsocket.handler_scan /var/www/websockets/
  PythonHeaderParserHandler mod_pywebsocket.headerparserhandler
</IfModule>

以下是此路径的列表，以便更好地了解"在哪里是什么"：

root@senior:/var/www/websockets# ls /usr/local/lib/python2.6/dist-packages/
mod_pywebsocket  mod_pywebsocket-0.7.8.egg-info
root@senior:/var/www/websockets# ls /usr/local/lib/python2.6/dist-packages/mod_pywebsocket

common.pyc      headerparserhandler.py   memorizingfile.py   standalone.py       _stream_hybi.py

root@senior:/var/www/websockets#
root@senior:/var/www/websockets# ls .
bench_wsh.py  console.html    echo_wsh.py      origin_check_wsh.py
close_wsh.py  echo_client.py  handler_map.txt  pywebsocket.conf

我还必须编辑 apache 的mod_reqtimeout以保持连接活动（有关更多信息，请参阅此问题 为什么使用 pywebsocket 创建的 websocket 会自动关闭？
