     * :cpp:func:`httpd_start`: Creates an instance of HTTP server, allocate memory/resources for it depending upon the specified configuration and outputs a handle to the server instance. The server has both, a listening socket (TCP) for HTTP traffic, and a control socket (UDP) for control signals, which are selected in a round robin fashion in the server task loop. The task priority and stack size are configurable during server instance creation by passing ``httpd_config_t`` structure to ``httpd_start()``. TCP traffic is parsed as HTTP requests and, depending on the requested URI, user registered handlers are invoked which are supposed to send back HTTP response packets.
     * :cpp:func:`httpd_stop`: This stops the server with the provided handle and frees up any associated memory/resources. This is a blocking function that first signals a halt to the server task and then waits for the task to terminate. While stopping, the task closes all open connections, removes registered URI handlers and resets all session context data to empty.
-    * :cpp:func:`httpd_register_uri_handler`: A URI handler is registered by passing object of type ``httpd_uri_t`` structure which has members including ``uri`` name, ``method`` type (eg. ``HTTPD_GET/HTTPD_POST/HTTPD_PUT`` etc.), function pointer of type ``esp_err_t *handler (httpd_req_t *req)`` and ``user_ctx`` pointer to user context data.

     * :cpp:func:`httpd_start`： 创建 HTTP 服务器的实例，根据具体的配置为其分配内存和资源，并返回该服务器实例的句柄。服务器使用了两个套接字，一个用来监听 HTTP 流量（TCP 类型），另一个用来处理控制信号（UDP 类型），它们在服务器的任务循环中轮流使用。通过向 ``httpd_start()`` 传递 ``httpd_config_t`` 结构体，可以在创建服务器实例时配置任务的优先级和堆栈的大小。TCP 流量被解析为 HTTP 请求，根据请求的 URI 来调用用户注册的处理程序，在处理程序中需要发送回 HTTP 响应数据包。
     * :cpp:func:`httpd_stop`： 根据传入的句柄停止服务器，并释放相关联的内存和资源。这是一个阻塞函数，首先给服务器任务发送停止信号，然后等待其终止。期间服务器任务会关闭所有已打开的连接，删除已注册的 URI 处理程序，并将所有会话的上下文数据重置为空。
