如何处理HTTP服务器中的多个请求？

Question

我正在使用以下代码在浏览器中显示我的图像。

import os, time
from glob import glob
import sys
from http.server import BaseHTTPRequestHandler, HTTPServer

boundary = '--boundarydonotcross'


def request_headers():
    return {
        'Cache-Control': 'no-store, no-cache, must-revalidate, pre-check=0, post-check=0, max-age=0',
        'Connection': 'close',
        'Content-Type': 'multipart/x-mixed-replace;boundary=%s' % boundary,
        'Expires': 'Mon, 3 Jan 2000 12:34:56 GMT',
        'Pragma': 'no-cache',
    }


def image_headers(filename):
    return {
        'X-Timestamp': time.time(),
        'Content-Length': os.path.getsize(filename),
        # FIXME: mime-type must be set according file content
        'Content-Type': 'image/jpeg',
    }


# FIXME: should take a binary stream
def image(filename):
    with open(filename, "rb") as f:
        # for byte in f.read(1) while/if byte ?
        byte = f.read(1)
        while byte:
            yield byte
            # Next byte
            byte = f.read(1)


# Basic HTTP server
class MyHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)
        # Response headers (multipart)
        for k, v in request_headers().items():
            self.send_header(k, v)
        # Multipart content
        while True:
            for filename in glob('img/*'):
                # Part boundary string
                self.end_headers()
                self.wfile.write((boundary).encode())
                self.end_headers()
                # Part headers
                for k, v in image_headers(filename).items():
                    self.send_header(k, v)
                self.end_headers()
                # Part binary
                for chunk in image(filename):
                    self.wfile.write(chunk)

    def log_message(self, format, *args):
        return


httpd = HTTPServer(('', 8001), MyHandler)
httpd.serve_forever()

但是，我无法将其用于多个客户端。即，当我在浏览器中点击localhost：8001时，它按预期运行。但是，如果我打开一个新选项卡并单击localhost：8001，则无法使用。基本上不允许我使用请求的资源。

任何帮助都是有意义的。
