如果您不熟悉 Discourse Discover，请查看 此主题。
我们最近为 Discourse Discover 添加了一个酷炫的新功能：您可以在您关心的主题中，查看跨 Discourse 社区的热门话题讨论。这在技术上是一个简单的改动，但对各类受众都非常实用。
它是如何工作的？
对于已纳入 Discover 的网站，我们现在运行一个爬虫程序，抓取最新最活跃的话题，并使用一个简单的算法按主题对这些话题进行分组。Discourse 社区涵盖众多主题，这为公众提供了一个窗口，让他们可以看到人们正在讨论哪些主题。
很酷，我在哪里可以看到这个功能？
目前，该功能已在我们 iOS 移动应用 DiscourseHub 中上线，并即将推出 Android 版本以及网站 discover.discourse.com。
您可以在以下视频和照片中抢先预览：
我可以在我的应用/网站上使用这个功能吗？
当然可以。我们将其构建为一个简单的 API，可供任何客户端调用。您只需使用以下两个端点：
https://discover.discourse.com/hot-topics-tags.json- 返回需要获取的主题/标签：https://discover.discourse.com/hot-topics.json?tag=<name>tag参数是必需的 — 没有“所有标签”模式；其他任何值都会返回400错误- 您可以传递
page参数以获取更多结果 – 它基于 0 索引，默认为 0，最多支持 5 页结果。
示例
首先获取可用的标签：
λ curl https://discover.discourse.com/hot-topics-tags.json
{
"tags": [
"ai",
"finance",
"apple",
"automation",
"media",
"research",
"smart-home",
"linux",
"open-source",
"webdev",
"health",
"gaming",
"audio",
"devops",
"crypto",
"mapping",
"technology",
"support",
"interests",
"programming"
]
}
然后，选择一个标签。例如，我将使用 ai，并将其传递给第二个端点：
curl "https://discover.discourse.com/hot-topics.json?tag=ai"
这将返回类似以下内容：

然后您可以列出这些话题。这些端点会在一天中不断更新，以确保每个主题的结果都是最新的。
