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：

  1. RSSAgent：获取并解析网站提供的 RSS 源；
  2. TriggerAgent：过滤 RSS 源中的项目；
  3. WebsiteAgent：通过 RSS 源中的项目获取文章的全文；
  4. 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

3. WebsiteAgent

Name: Example page fetch
Event sources: Example filter
Propagate immediately: Yes

{
  "expected_update_period_in_days": "14",
  "url": "",
  "type": "html",
  "mode": "merge",
  "extract": {
    "imgurl": {
      "css": "\#comic img",
      "value": "@src"
    }
  }
}

注意：将 mode 设置为 merge，从而将解析的项目元素传递给下一个 agent

4. DataOutputAgent

Name: Example Rss out
Event sources: Example page fetch
Propagate immediately: Yes

{
  "secrets": [
    "examplerss"
  ],
  "expected_receive_period_in_days": "14",

    "title": "Business Cat full comic feed",
    "description": "This is a feed of recent Business Cat comics generated by Huginn",
    "item": {
      "title": "",
      "description": "<img src=\"\" />",
      "link": "",
      "pubDate": ""
    }
  }
}
