我嘗試過使用以下的程式碼

    from http.server import BaseHTTPRequestHandler, HTTPServer
    from numbers import Number

    times = None

    class RequestHandler_httpd(BaseHTTPRequestHandler):
      def do_GET(self):
        global times
        times = (times if isinstance(times, Number) else 0) + 1
        messagetosend = bytes(times,"utf")
        self.send_response(200)
        self.send_header('Content-Type', 'text/plain')
        self.send_header('Content-Length', len(messagetosend))
        self.end_headers()
        self.wfile.write(messagetosend)
        print(self.requestline)
        return


    server_address_httpd = ('IP',8080)
    httpd = HTTPServer(server_address_httpd, RequestHandler_httpd)
    print('starting server')
    httpd.serve_forever()
    times = 0

但是當我在網址列輸入'IP':8080時
得不到預期中的效果
請問可以幫忙修改程式碼嗎?
