Node Red 实现电视剧更新自动提醒

KevinYAN

最近在追个电视剧，由于免费网站更新电视剧的时间不定，为了尽早追到，不断的刷新网页不是一个太好的操作。
于是有了下边的流程。

效果如下：
微信可以收到一条消息，并且小爱也会进行语音播报。



实现思路，在网站F12调试跟踪，根据对多个免费网站的跟踪，发现都能提取到一个数组，记录电视剧每集的资源地址。

示例：
《以爱为营》全集在线观看-国产剧_西瓜影音_西瓜影院_免费在线 (xigua60.com)



如图，是可以非常轻松的拿到每一集电视剧的m3u8文件的。判断这个video数组的数量，就可以实现判断是否有更新。

题外话:
   m3u8文件实际是个目录文件，每一集电视剧40多分钟，会别切分成很多很小的片段，每一个片段的地址信息，就记录在这个文件中。以前还通过这个文件下载电视剧。脚本也是比较容易实现。


我这里直接放流程代码：

复制代码

流程简要说明：
     流程时间范围，取了最容易更新的时间段，配合后边30合并节点，实现了18:30-22：00每一分钟判断一次，其他时间每30分钟判断一次。 不建议太频繁获取。

   http请求直接请求数组信息的url, 获取到数组信息后，”提取“节点对字符串进行了删减处理，然后转为json, 在通过”判断“节点进行数量判断。 最后输入的小爱播报就行。





以后追剧了，只需要F12复制这个链接到node red，即可实现自动更新提醒。  

可能大佬们还有更好的思路，欢迎交流学习。



文本导入提示括号截取的问题，这里重新放下导出文件：

这个是一个一个选的，测试没问题。

恩，看到看，字符串截取的括号。这个是论坛编辑器的问题。 你在上文最下边下载flows文件导入吧。

楼主，你导出文件没导出全呀。
