     * :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. ``HTTP_GET/HTTP_POST/HTTP_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_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。
     * :cpp:func:`httpd_register_uri_handler`： 通过传入 ``httpd_uri_t`` 结构体类型的对象来注册 URI 处理程序。该结构体包含如下成员：``uri`` 名字，``method`` 类型（比如 ``HTTP_GET/HTTP_POST/HTTP_PUT`` 等等）， ``esp_err_t *handler (httpd_req_t *req)`` 类型的函数指针，指向用户上下文数据的 ``user_ctx`` 指针。
