Question

我正在使用

 python -m SimpleHTTPServer

是一个非常简单的Web服务器，供内部用户访问测试服务器上的数据文件。

SimpleHTTPServer的默认列表非常简单。它只显示文件链接。

如何让它显示文件时间戳呢？我很乐意编写一个自定义类来扩展SimpleHTTPServer

我目前正在使用python 2.4.3

你可以继承SimpleHTTPRequestHandler：

import cgi, os, SocketServer, sys, time, urllib
from SimpleHTTPServer import SimpleHTTPRequestHandler
from StringIO import StringIO

class DirectoryHandler(SimpleHTTPRequestHandler):
    def list_directory(self, path):
        try:
            list = os.listdir(path)
        except os.error:
            self.send_error(404, "No permission to list directory")
            return None
        list.sort(key=lambda a: a.lower())
        f = StringIO()
        displaypath = cgi.escape(urllib.unquote(self.path))
        f.write('<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">')
        f.write("<html>\n<title>Directory listing for %s</title>\n" % displaypath)
        f.write("<body>\n<h2>Directory listing for %s</h2>\n" % displaypath)
        f.write("<hr>\n<ul>\n")
        for name in list:
            fullname = os.path.join(path, name)
            displayname = linkname = name
            date_modified = time.ctime(os.path.getmtime(fullname))
            # Append / for directories or @ for symbolic links
            if os.path.isdir(fullname):
                displayname = name + "/"
                linkname = name + "/"
            if os.path.islink(fullname):
                displayname = name + "@"
                # Note: a link to a directory displays with @ and links with /
            f.write('<li><a href="%s">%s - %s</a>\n'
                    % (urllib.quote(linkname), cgi.escape(displayname), date_modified))
        f.write("</ul>\n<hr>\n</body>\n</html>\n")
        length = f.tell()
        f.seek(0)
        self.send_response(200)
        encoding = sys.getfilesystemencoding()
        self.send_header("Content-type", "text/html; charset=%s" % encoding)
        self.send_header("Content-Length", str(length))
        self.end_headers()
        return f

httpd = SocketServer.TCPServer(("", 8000), DirectoryHandler)
print "serving at port", 8000
httpd.serve_forever()

这可能看起来很多，但实际上我只是在list_directory方法中添加了一行：

    date_modified = time.ctime(os.path.getmtime(fullname))

...然后将其添加到目录列表输出中。

python：如何重写SimpleHTTPServer以在目录列表中显示时间戳？
