为什么Ocsigen无法运行我的python文件？

Question

的配置文件test.conf是如下：

<ocsigen> 
<server> 
<port>*:8000</port> 

<logdir>/home/zaxis/tmp/log/</logdir> 
<datadir>/home/zaxis/tmp/data</datadir> 
<user>zaxis</user> 
<group>wheel</group> 
<charset>utf-8</charset> 
...... 
<extension findlib-package="ocsigen_ext.cgimod"> 
    <cgitimeout value="30"/> 
</extension> 

<extension findlib-package="ocsigen_ext.staticmod"/> 
...... 
<site path="qachina" charset="utf-8"> 
    <cgi root="cgi-bin" dir="/media/E/www/qachina/cgi-bin"/> 
    <static dir="/media/E/www/qachina" /> 
</site> 
.... 
<commandpipe>/home/zaxis/tmp/ocsigen_command</commandpipe> 
</server> 
</ocsigen> 

然后我跑Ocsigen：

ocsigeocsigen -c test.conf

我可以访问http://127.0.0.1:8000/qachina/index.htm。但是，Ocsigen不会在cgi-bin中执行我的python脚本，但希望浏览器下载它。

顺便说一下，所有的python脚本文件都可以直接在shell中运行。

>head cgi-bin/nav.py 
#!/usr/bin/env python 
# -*- coding: utf-8 -*-enter code here 
... 

我不能访问Ocsigen的邮件列表，所以我在这里发布的建议。

Answer 1

什么是您的Ocsigen版本？

我刚刚尝试过使用ocsigen 1.3.4（目前在Debian测试中的版本），并且您的配置代码段中似​​乎存在一个错误（在Ocsigen方面）。

<cgi regexp="cgi-bin/([^/]*)" dir="/usr/lib/cgi-bin/" script="\1" /> 

我刚刚检查了，我有机会获得Ocsigen的所有正在运行的情况下，他们都用“正则表达式”属性：你想要什么可以实现。虽然文档确实允许您的版本，并且服务器接受它。这两个选择之一是一个错误。

仅供参考，运行ocsigen与-V选项帮助。

Answer 2

我不知道任何可靠的答案，因为它看起来像我应该工作，但我确实有一些可能有用的问题。

当系统提示您下载时，您是否真的下载过它？如果是这样，你是下载由脚本产生的网页还是你自己下载脚本？如果它是前者，那么它只是某种类型的mime类型的问题。如果是后者，听起来更像是服务页面的静态模块而不是CGI的问题。您是否尝试删除<static dir="/media/E/www/qachina" />以查看是否存在冲突？

Answer 3

对于网站上的每个请求，Ocsigen会尝试按照配置文件的顺序列出的扩展名。在你的情况下，它会尝试staticmod，这是成功的，因为cgi-bin是存在于给予staticmod的目录中的一个目录。如果您希望先尝试cgimod，则应在<static ...>之前放<cgi ...>。

改变#!/usr/bin/env python到#!/usr/local/bin/python每个Python文件后，似乎现在的工作！

谢谢！
