问题描述

我以前从未设置过服务器(更不用说python服务器)了,我有点迷茫。我如何利用以下代码?我试过放在cgi bin目录中,但是没有用。它返回了内部服务器错误。在

I have never setup a server (let alone a python server) before and i am a bit lost. How do i utilize the following code? I have tried to put in in the cgi bin directory but that didnt work. It returned an internal server error. have a look at this here

推荐答案

如果要在Apache之类的计算机上运行CGI(与上面粘贴的自定义服务器代码相对),则可以在(.py)启用CGI的目录中创建一个.py文件。

If you want to run a CGI on something like Apache (as opposed via custom server code like you pasted above), you can create a .py file like this in a (.py) CGI-enabled directory.

#!/usr/bin/env python
print "Content-Type: text/html"
print
print 'Hello World'

如果您使用的是Apache,则。

If you're using Apache, here's some info on how to set up CGI executables.

编辑:(正如Adrien P.所说,应将Python脚本设为可执行文件。)

edit: (As Adrien P. says, the Python script should be made executable.)
