AT方式：

首先需要烧写AT_S_SSL的版本，此版本才支持HTTPS

http://www.openluat.com/Product/gprs/Air202.html 资料下载->二次开发(AT)

HTTPS下载的数据是存储在内存中的，最大支持300K字节

有两种方式下载：

第一种方式：

如果下载的文件内容小于300K，可以直接保存在内存中，下载结束后，再读取内容到MCU，此方式的缺点是：如果文件内容较大，网络环境较差时，会高概率失败

下面以下载https://www.baidu.com主页为例说明此方式

第二种方式：

采用断点续传下载，不受下载内容的大小限制，下载内容较大时，即使网络较差，下载的成功率仍然比第一种方式高
