/**
 * @file example_http_client.c
 * @brief Demonstrates HTTP client usage in Tuya SDK applications.
 *
 * This file provides an example of how to use the HTTP client interface provided by the Tuya SDK to send HTTP requests
 * and handle responses. It includes initializing the SDK, setting up network connections (both WiFi and wired,
 * depending on the configuration), sending a GET request to a specified URL, and handling the response. The example
 * also demonstrates how to handle network link status changes and perform cleanups.
 *
 * Key operations demonstrated in this file:
 * - Initialization of the Tuya SDK and network manager.
 * - Sending an HTTP GET request and receiving a response.
 * - Handling network link status changes.
 * - Cleanup and resource management.
 *
 * This example is intended for developers looking to integrate HTTP communication into their Tuya SDK-based IoT
 * applications, providing a foundation for building applications that interact with web services.
