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

问题描述

YouTube API使用户可以获取评论供稿，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，当我尝试使用直播视频ID进行操作时，无论提交了多少评论，结果始终为空.实况视频和任何其他视频(或实况流的录制)之间的唯一区别是，评论"部分被聊天"框取代，聊天"框似乎无法通过API获得注释.

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.

当流停止时，通过聊天框提交的所有评论将完全消失"，无法再访问.但是，在直播中存档(即已提供录音)之后提交的所有评论都会显示在评论供稿中.

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 However, all comments submitted after the live broadcast has been archived (i.e. the recording has been made available) show up in the comments feed.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，我需要在广播仍在直播时访问聊天"注释，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

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

在创建新的liveBroadcast对象时，将返回liveChatId字符串作为该liveBroadcast的snippet的一部分.将广播的聊天ID传递到LiveChatMessages/list端点的liveChatId参数，并将id，snippet和authorDetails传递到part参数.

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词典中，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
}
