在Python中将MIME类型与HTTPServer混合

Question

Right now I have this file structure 现在我有这个文件结构

server-
      |
      |css-
      |   |bad.css
      |
      |html-
      |    |bad.html
      |
      |jpg-
      |      |bad.jpg
      |
      |server.py

this is bad.css: 这是bad.css：

body
{
    background-image:url('bad.jpg');
    background-repeat:no-repeat;
    background-position:right top;
    margin-right:200px;
}

this is bad.html: 这是bad.html：

<html>
<head>
<link rel="stylesheet" type="text/css" href="bad.css">
</head>
<body>
    <h1>This isn't a thing!</h1>
    <p>You must be mistaken. But <a href="/index">here</a> is where you can find your way again.</p>
</body>
</html>

this is the relevant part of server.py 这是server.py的相关部分

from BaseHTTPServer import BaseHTTPRequestHandler as Handler
from mime types import guess_type

class MyHandler(Handler):
    def do_GET(self):
        print self.path
        print self.headers
        extensions = ['html', 'css', 'jpg']
        fname = self.path
        for ext in extensions:
            if fname.endswith(ext):
                fname = ext + fname
                break
        if fname.split('/')[0] == '':
            fname = 'html/bad.html'
        mimetype = guess_type(fname)[0]
        print fname
        data = open(fname, 'rb')
            self.send_response(200)
        self.send_header('Content-type', mimetype)
        self.end_headers()
        self.wfile.write(data.read())
        data.close()

My updated code should have fixed it, but now my browser doesn't render it at all, it just shows html code. 我更新的代码应该已经修复了它，但是现在我的浏览器根本不渲染它，只显示了html代码。 我所看到的屏幕截图

The reason why your css and images won't load is because your handler doesn't know how to handle the request(s) for those files. 您的CSS和图片无法加载的原因是，您的处理程序不知道如何处理这些文件的请求。 Here is a simple example copied (and tweaked abit) from nosklo's answer in the question you linked to. 这是一个简单的示例，它从您链接到的问题的nosklo的答案中复制（并稍作调整）。

def do_GET(self):
    try:
        if self.path in ("", "/"):
            filepath = "html/bad.html"
        else:
            filepath = self.path.lstrip("/")

        f = open(os.path.join('.', filepath), "rb")

    except IOError:
        self.send_error(404,'File Not Found: %s ' % filepath)

    else:
        self.send_response(200)

        #this part handles the mimetypes for you.
        mimetype, _ = mimetypes.guess_type(filepath)
        self.send_header('Content-type', mimetype)
        self.end_headers()
        for s in f:
            self.wfile.write(s)

NB: You will have to change the css link in your html from 注意：您必须将html中的css链接从

<link rel="stylesheet" type="text/css" href="../css/bad.css">

to 至

<link rel="stylesheet" type="text/css" href="/css/bad.css">
