如何在getstream-io中创建公共活动

Question

我想广播一些活动，比如“用户加入”，让所有的成员都能看到。目前我有一个扁平的user提要。有没有办法推送一个活动，让每个人都能看到？

Answer 1

您可以使用TO字段将活动添加到全局提要。例如：

// Instantiate a feed using feed class 'user' and user id '1'
var user1 = client.feed('user', '1');
// Add an activity to the feed
var activity = {"to": ["user:global"], "actor": "User:1", "verb": "pin", "object": "Place:42", "target": "Board:1"};
user1.addActivity(activity)
// activity is added to both user:1 as well as user:global

或者，你可以有一个社论账号，所有用户都会关注这个账号。
