如何在 YouTube 直播期间获取通过“聊天"框输入的评论源? [英] How to obtain a feed of comments entered through the 'chat' box during a YouTube live broadcast?

问题描述

YouTube API 使用户能够获取评论供稿，例如通过 https://gdata.youtube.com/feeds/api/videos/VIDEO_ID/comments?orderby=published.

The YouTube API enables users to obtain a comments feed, e.g. via https://gdata.youtube.com/feeds/api/videos/VIDEO_ID/comments?orderby=published.

但是，当我尝试使用直播的视频 ID 执行此操作时，无论提交了多少评论，结果始终为空.直播视频与任何其他视频(或直播视频录制)之间的唯一区别是评论"部分被替换为聊天"框，其评论似乎无法通过 API 获得.

However, when I try to do just that with the video ID of a live stream, the result is always empty, no matter how many comments have been submitted. The only difference between a live video and any other video (or recording of a live stream) is that the 'comments' section is replaced with a 'chat' box, whose comments seem not to be available via the API.

流停止后，通过聊天框提交的所有评论都将完全消失"，无法再访问.但是，在直播存档后提交的所有评论(即已提供录音)都会显示在评论源中.

When the stream is stopped, all comments submitted through the chat box 'disappear' entirely and can no longer be accessed. However, all comments submitted after the live broadcast has been archived (i.e. the recording has been made available) show up in the comments feed.

对于实时应用程序，我需要在直播期间访问聊天"评论，以检索用户提交的问题.

For a real-time application I need to access the 'chat' comments while the broadcast is still live, to retrieve user-submitted questions.

有什么办法吗?

推荐答案

现在可以使用 LiveChatMessages 端点，作为 YouTube Live Streaming API 的一部分.

It is now possible to return chat messages for your own broadcasts using the LiveChatMessages endpoint as part of the YouTube Live Streaming API.

当创建一个新的 liveBroadcast 对象时，一个 liveChatId 字符串将作为该 liveBroadcast 的 snippet.将广播的聊天 ID 传递给 LiveChatMessages/list 端点的 liveChatId 参数，以及 id、snippet 和 将 authorDetails 添加到 part 参数中.

When creating a new liveBroadcast object, a liveChatId String will be returned as part of that liveBroadcast's snippet. Pass your broadcast's chat ID to LiveChatMessages/list endpoint's liveChatId parameter, and id, snippet, and authorDetails into the part parameter.

HTTP GET https://www.googleapis.com/youtube/v3/liveChat/messages?liveChatId={liveChatId}&part=id%2C+snippet%2C+authorDetails&key={YOUR_API_KEY}

这将返回一组 liveChatMessage 资源.实际的聊天消息包含在 textMessageDetails 字典中，作为 messageText 键的值.

This will return an array of liveChatMessage resources. The actual chat message is contained in the textMessageDetails dictionary as the value for the messageText key.

"textMessageDetails": {
  "messageText": string
}
