HTTP 客户端

功能概述

本例演示了如何实现一个简单的 HTTP 客户端。

环境要求

  1. 需要有一个能正常连接的 AP。

  2. 在 menuconfig 中配置 WiFi SSID 和 WiFi Password。

编译和烧录

示例位置：examples/network/http_client

编译、烧录等操作请参考：快速入门

注意

示例中请求的地址包含 www.baidu.com, www.qq.com 等地址，获取内容有中文等符号，部分终端打印可能存在乱码。 且由于时间不同获取到的内容也不相同，使用者可以参考当时上述域名显示内容对比参考。

运行结果

成功运行将输出如下日志
