// 这里演示上传一个图像数据, 实际数据的来源是多种多样的,不局限于文件
// File f = new File("abc.jpg");
// byte[] buf = new byte[(int)f.length()];
// new FileInputStream(f).read(buf);
// upload(12825, 20956, buf);

// 上传一个泛型数据, 参考api可知需要上传一个json格式数据
// 其中key是一个唯一键值, value是数据, 可以是复杂的,也可以简单一个字符串
// 复杂的数据应借助Json序列化类库,而不是下面的拼字符串哦
String str = String.format("{\"key\":\"%s\", \"value\":{\"mytext\":\"%s\"}}", System.currentTimeMillis(), "http://wendal.net");
upload(12825, 21749, str.getBytes());
}
}

 

程序没报错,但网上依然没有新插入的数据http://api.yeelink.net/device/340600/sensor/377291/datapoints
