mod_python returns 空白屏幕

Question

我正在尝试运行 mod_python.publisher 在 apache2 中。我只想打印 "Hello World"

当我运行我的程序时，我得到一个空白屏幕。我的 .py 程序如下所示：

def index():
    print ("Hello World")
index()

但是当我运行程序时：

def index(req):
    print ("Hello World")
index()

我收到此错误消息，指出 index() 需要和参数并且给出了 0：

MOD_PYTHON ERROR

    index()

    TypeError: index() takes exactly 1 argument (0 given)

因此，基于此，我的代码似乎正在被编译。我从错误的代码中得到一个错误，但没有输出好的代码。有什么想法吗？

这最终对我有用：

#!/usr/bin/python
from mod_python import apache

def index(req):
    out = "<html><head>"
    out = out+"<meta http-equiv='content-type' content='text/html'></head>"
    out = out+"<body>Hello World</body></html>"
