我在自己的线程上运行一个 http 服务器，并使用以下代码发出 PUT 请求。
服务器端：

thread = threading.Thread(target=run, args=[self.__infoPort])
        thread.daemon = True
        thread.start()

class V6Server(HTTPServer):
    address_family = socket.AF_INET6

def run(port):
    try:
        server = V6Server(('::', port), CustomHandler)
        server.serve_forever()
    except Exception:
        logging.error("Could not establish or maintain HTTP server")

class CustomHandler(SimpleHTTPRequestHandler):
    def do_PUT(self):
        secureNetworkFile = open(self.path, "r+")
        secureNetworkJson = json.load(secureNetworkFile)
        requestBody = self.rfile.read()
        requestBodyJson = json.loads(requestBody)

        secureNetworkJson["id"] = requestBodyJson["id"]
        secureNetworkJson["master-key"] = requestBodyJson["key"]

        secureNetworkFile.seek(0)
        json.dump(secureNetworkJson, secureNetworkFile, indent=4)
        secureNetworkFile.truncate()
        secureNetworkFile.close()

        self.send_response(204)
        self.wfile.write("PUT success!\n".encode('utf8'))
        self.end_headers()
        return

客户端：

        requestBody = {
            "id": self.__secureNetwork.get_id(),
            "key": self.__secureNetwork.get_key(),
            "pairingMethod": ""
        }

        connection = http.client.HTTPConnection(address, pairingPort, timeout=60)
        
        requestBodyJson = json.dumps(requestBody)
        
        headers = {'Content-type': 'application/json'}
        
        connection.request("PUT", pairingPath, body=requestBodyJson, headers=headers)
        response = connection.getresponse()

当我在主线程上与服务器建立连接并使用上述代码发出 PUT 请求时，没有收到任何响应。self.send_response(204)除非在 do_PUT() 的第一行，否则请求会挂起。我想根据情况打开并写入文件并发送响应代码，但这会导致客户端根本没有响应。我不确定在 do_PUT() 处理程序中还可以尝试什么来给客户端一个正确的响应。有什么我可以尝试的吗？
