Web scraping 如何首先从特定频道抓取新的YouTube视频？

我有一个频道，我想从它得到一个新的上传视频尽快。最好的方法是什么？我知道有两个选择：

使用YouTube API

直接通过url访问频道

使用选项1，我需要调用api以获得视频列表。既然有了配额，我想我将无法进行api调用。我认为选项2是最好的选择，因为我可以随时调用url

---

是否首先通过api提供新视频？或者，根据用户来自的地区，通过url访问的视频是否在不同的时间提供给用户？我自己建立了一个url刮刀。我每分钟访问一次url。还有人在我拿到录像带前8分钟拿到了录像带。我不明白为什么会出现这种情况。

您可以尝试RSS订阅感兴趣的频道。它包含带有UTC时间戳的新视频（因此您提到的时区没有问题）

该频道视频的RSS链接可以在该频道页面的源位置找到。打开页面源代码并搜索“rssUrl”：

只需在MadRay写的内容基础上做一点扩展，就可以使用此URL进行一些简单的字符串替换

使用通道ID：

html = requests.get(url)
soup = BeautifulSoup(html.text, "lxml")

for entry in soup.find_all("entry"):
