爲什麼我有時會從BBC Weather RSS Feed下載垃圾數據？

Question

從BBC的RSS天氣預報下載時，我會隨機查找文本/數據，以免發生奇怪的損壞。奇怪的是，如果我直接從網站加載而不是下載，就會發生這種情況。這可能是內存問題嗎？它是如此隨機，但70％的時間，其中一個位置將被下載錯誤。

Answer 1

我已經從BBC天氣RSS請求時，剛看到同樣的事情，第一次在我的網站從代碼源。

我只是說這是用BBC的網站供稿ŧ ØCloudFlare的，但我不能看到如何可能與

我添加一個隨機的查詢字符串到BBC RSS提要URL的末尾，以便我的網址是這樣的：。

http://open.live.bbc.co.uk/weather/feeds/en/2634135/3dayforecast.rss?123

而且該問題立即得到解決。

需要注意的是，如果我要求手飼料直接在自己的瀏覽器，它是工作的罰款。
