OpenWrt luci怎么添加上传下载及网络摄像头功能

本篇内容介绍了"OpenWrt luci怎么添加上传下载及网络摄像头功能"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

花了几天时间给OpenWrt弄了个上传下载及网络摄像头功能。对lua及luci不熟，时间花的有点多。此软件包是纯luci应用，可以安装在任意平台，网络摄像头要依赖mjpg-streamer。效果图如下：

主要源码如下：

controller/updownload.lua文件：

为了使添加的软件包能在openwrt源码make menuconfig时识别出来，需要在./feeds/luci/contrib/package/luci/Makefile增加如下语句：

$(eval $(call application,other,luci my other application))
