筛选 RSS 源，制作新的全文 RSS 源
问题：假如你喜欢的网站只提供摘要型的 RSS 源，但是你希望能在 RSS 阅读器中阅读全文 RSS，同时还希望它只推送某些特定的文章 解决方法：利用 Huginn 制作一个经过筛选的全文 RSS 源，实现方法如下：
- RSSAgent：获取并解析网站提供的 RSS 源；
- TriggerAgent：过滤 RSS 源中的项目；
- WebsiteAgent：通过 RSS 源中的项目获取文章的全文；
- DataOutputAgent：输出全文 RSS。
1. RSSAgent
Name: Example RSS In
{
"expected_update_period_in_days": "14",
"clean": "false",
"url": "http://www.businesscat.happyjar.com/feed/"
}
2. TriggerAgent
Name: Example filter Event sources: Example RSS In Propagate immediately: Yes
{
"expected_receive_period_in_days": "14",
"keep_event": "true",
"rules": [
{
"type": "regex",
"value": ".*\\/comic\\/.*",
"path": "url"
}
]
}
注意：将
keep_event设置为true，从而将解析的项目元素传递给下一个 agent
