linux下向yeelink添加数据点

http://blog.csdn.net/liang890319/article/details/8615666

初步简单的实现 并不完整

linux下最简单的实现方式就是curl来实现

请求实例 (运用curl):
curl --request POST --data-binary @datafile.txt --header "U-ApiKey: YOUR_API_KEY_HERE" http://api.yeelink.net/v1.0/device/12/sensor/3/datapoints
需要在HTTP Header中增加API Key来授权写入操作, 具体请参照API Key. 支持一次传送一个数据或者批量上传.

这里的代码是纯c实现的

为了将来方便移植到lwip

目前函数都已经修改

这是最基本的测试

三个文件

client.c  发送http请求给服务器

server.c 用来测试client发送的数据对不对

makefile用来编译上面的两个文件

使用时之需要执行client.c即可 没写退出函数 所以暂时用 ctrl+c结束进程

使用时先make

然后./client

client.c  发送http请求给服务器
