Following the tutorial on the Internet, I used Python to write a CGI file to upload, but 500 kept appearing. What’s going on? html file: {code...} .py file {code...} Error message: {code...}

Don’t you think the URL in your error message looks weird? Open it in your browser and take a look. Shouldn’t it be studycgi.com

Isn’t the error message relatively clear: Response header name '<!--' contains invalid characters

[Problem with Python uploading files] When uploading files according to online tutorials, 500 errors keep appearing.

Follow the tutorial on the Internet and use Python to write CGI to upload files, but 500 keeps appearing. What's going on?

html file:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>文件上传</title>
</head>
<body>
    <form enctype="multipart/form-data" action="save_file.py" method="post">
        <p>
            选中文件: <input type="file" name="filename" />
        </p>
        <p>
            <input type="submit" value="上传"/>
        </p>
    </form>
</body>
</html>

.py file

#!/usr/bin/python
# -*- coding:utf-8 -*-

import cgi, os
import cgitb; cgitb.enable()

# 获取文件名
f = cgi.FiledStorage().getvalue('filename')

# 检测文件是否上传
if f is not  None:
    # 设置文件路径
    fn = os.path.basename(f.filename.replace("","/"))
    open('/tmp/' + fn,'wb').write(f.file.read())

    message = '文件 "' + fn + '" 上传成功'

else:
    message = "文件没有上传"

print """
    Content-Type:text/html
    <html>
        <head>
            <meta charset="utf-8">
            <title>文件上传</title>
        </head>
        <body>
            <p> %s </p>
        </body>
    </html>
""" % (message,)

error message:
