如何在python中删除响应头中的服务器名(SimpleHTTPRequestHandler)

from http.server import SimpleHTTPRequestHandler

class MyRequestHandler(SimpleHTTPRequestHandler):
    def end_headers(self):
        self.send_response_only(200, 'OK')
        self.send_header('Content-type', self.extensions_map.get(self.path, 'text/plain'))
        self.send_header('Date', self.date_time_string())
        self.send_header('Server', '')  # 删除服务器名
        self.end_headers()

if __name__ == '__main__':
    from http.server import HTTPServer
    server = HTTPServer(('localhost', 8000), MyRequestHandler)
    server.serve_forever()
