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

这是我在 httpd.conf

中插入的文字

<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apaceh后，我正在尝试使用pywebsocket目录中的console.html代码（复制在/ var / www / _wsh中）。但它不起作用，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'

你可以帮我找一下问题所在吗？谢谢

将它作为独立服务器运行要容易得多。你试过了吗？

"""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.

在阅读了很多关于如何设置pywebsockets的教程之后，我结束了以下配置：

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>

以下列出了这些路径，以便更好地了解其中的内容：

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.py       handshake                __init__.pyc        mux.pyc             _stream_hixie75.pyc  util.pyc
common.pyc      headerparserhandler.py   memorizingfile.py   standalone.py       _stream_hybi.py
dispatch.py     headerparserhandler.pyc  memorizingfile.pyc  standalone.pyc      _stream_hybi.pyc

extensions.py   http_header_util.pyc     msgutil.pyc         _stream_base.pyc    stream.pyc
extensions.pyc  __init__.py              mux.py              _stream_hixie75.py  util.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（请参阅此问题以获取更多信息Why would a websocket created with pywebsocket be closed automatically?）

pywebsocket不起作用
