【问题描述】：
编辑** 来自this postJon 提到他希望在 2.0 中摆脱并发，而是在应用程序中传递单个 url 并处理并发，工人是可能的方法。
我正在尝试使用 FeedJira 解析多个 URL（使用 farday gem），但收到参数错误。过去有没有人成功解析过一个以上的 URL？ FeedJira::Feed 的 The source 声明它将返回单个提要 URL 或提要 URL 数组。
.fetch_and_parse(urls, options = {}) ⇒ Object
脚本
feed_urls = ["https://jobs.startupnorth.ca/jobs.rss", "https://jobs.startupnorth.ca/jobs.rss"]
feed = Feedjira::Feed.fetch_and_parse(feed_urls)
错误

以上两个网址中的一个网址对你有用吗？
-
@TimmyVonHeiss 是的，我可以使用单个 URL 解析各种提要
-
@JagdeepSingh 我很欣赏您的回复，但是这不是我的问题

只是在检查这是否是一个选项。 :)
