Python CGI - 标头之前的脚本输出结束答案

【问题描述】：

我创建了一个简单的脚本，它可以读取 HTML 文件并解析其中的一些变量。然后它会创建一个新文件并将 HTML 代码写入其中。之后，它应该将您重定向到新创建的文件。但我收到此错误：标题前脚本输出结束。

这是我的 Python 代码：

#!C:\Program Files\Python36\python.exe

import cgi, urllib.request

data = cgi.FieldStorage()

def varordef(name, default):
   return default if data.get(name) == None else data.get(name)

page_title = varordef('page_title', 'Example CGI')

with urllib.request.urlopen('homepage.thtml') as response:
   html = response.read() % (page_title)
   file = open('homepage.html', 'w')
   file.write(html)

print('Content-type: text/html\n\r') # I've already tried removing this line, but that gives me the same error
                                     # And I also tried putting this line on the top, but then I just get a blank page and it doesn't redirect you
                                     # Also, I tried to put both of those headers on the top, and then it redirects me to the specified URL, but the code below wasn't executed and it didn't create the file, so I get a 404


print('Location: homepage.html\n\r')

HTML 文件：

<html>
<head>
    <title>{0}</title>
    <link rel='stylesheet' type='text/css' href=''>
</head>
<body>
    <form action='getfullname.py' method='get'>
        <p id='box-first_name'>
            Please enter your first name:
            <input type='text' id='first_name'>
        </p>
        <p id='box-last_name'>
            Please enter your last name:
            <input type='text' id='last_name'>
        </p>
        <p id='box-full_name'>
            This is your full name:
            <input type='text' id='full_name' disabled>
        </p>
        <p id='box-submit'>
            <input type='submit' id='submit'>
        </p>
    </form>
</body>
</html>
