Arduino+W5100 通过LeweiClient上传数据，不用再理解http了-乐联网应用

laoliu1982

之前用W5100，参考cosm client的程序，上传，感觉对于不了解http的爱好者用起来不是很友好，比如计算content-length的时候，不容易描述清楚，最近把http post的过程封装成了LeweiClient 类库，去掉了类似content-length 的计算过程，终于让数据上传乐联网不用再了解http 的相关细节了。

代码已经更新到 https://github.com/lewei50/leweiclient  可能与这里的不一致，以github上面为准



需要把 LeweiClient 两个文件(leweiclient.c   leweiclient.h )放到 librariesLeWei 里并且在 IDE 里引用，USER_KEY  需要修改

这两天就发一个28J60的

太惭愧了，直接把rt-thread的art板上面跑的给传上来了，已经更新附件，谢谢muggle

迷你强

封装成库才好用。。。顺便建议，写一下库语法的教程。。。。。

五月的风

麻烦问一下“LeWeiClient *lwc;”编译的时候总是报错，是怎么胡思hi呢

Alexie

http不靠谱... 为了服务器偶尔要查询下设备状态就得让设备自己没事一直去轮询...多本末导致啊

alex ,这不是控制用的啊
