Question

我创建了一个脚本，该脚本转到房地产拍卖网站，该网站监视价格并向我发出任何更改的警报。我最初是一次监视1个URL。现在，我需要它来监视超过1个网址，并同时执行相同的确切过程。

我尝试循环浏览器中的URL，但这似乎对我不起作用（idk，如果我写错了，大概可以）。但是我需要它来打开大量新标签并转到url，或者用另一种方式来监视所有内容。

用于1个属性url的原始脚本可以很好地工作，并且它与下面的代码之间的唯一区别是browser.get。

PS：如果运行脚本，并且拍卖网址已过期（这意味着它无法查看价格），则会出现错误

您的代码似乎很好，并为我循环遍历它们。不幸的是，所有财产都不出售，因此它们都会给我带来错误，并且我无法产生预期的行为。我认为您应该实现field :posts, type: :posts_by_state do resolve fn _, _, _ -> {:ok, []} end end和try:，无论发生了什么，except:都会运行，并且我无法想象您希望每隔2秒XD更新一次。最后，您也不需要finally:，它什么也没做。代码

continue

循环浏览所有属性，对我来说，示例输出是：

以此类推，无限循环...
