从 API 获取点赞帖子的用户列表

开发
1

So, when we get a post like so:

GET /posts/13.json

We can see in the json actions_summary which contains the number of likes the post has. And you can deduce if the user I am logged in as has liked if “acted” or “can_act” is present.

"actions_summary": [
          {
            "id": 2,
            "count": 2,
            "acted": true
          },

But, how do I lookup which users liked the post? We have 2 likes here, one is mine since “acted” is true. But there is one other like. How do I find out which user that is through the API? It is fine if we have to use an admin account to check.

As explained at How to reverse engineer the Discourse API

curl 'https://meta.discourse.org/post_action_users?id=507029&post_action_type_id=2'

Your link does not work.

This works for me though:

GET /post_action_users?id=13&post_action_type_id=2

This outputs

{
  "post_action_users": [
    {
      "id": 1,
      "username": "ausername",
      "name": null,
      "avatar_template": "/letter_avatar_proxy/v2/letter/i/{size}.png",
      "post_url": null,
      "username_lower": "ausername"
    },
    {
      "id": 10,
      "username": "anotherusername",
      "name": null,
      "avatar_template": "/letter_avatar_proxy/v2/letter/{size}.png",
      "post_url": null,
      "username_lower": "anotherusername"
    }
  ]
}

Which is a list of users who liked the post with id 13

It was missing the accept header:

curl 'https://meta.discourse.org/post_action_users?id=507033&post_action_type_id=2' -H 'Accept: application/json'

你需要传递

/post_action_users.json?id=507033&post_action_type_id=2

您好！

我正在尝试为我们公司使用的 Discourse 论坛（https://discuss.blues.io）确定类似的事情。

我拥有员工级别的凭证，但是，当我查看已被点赞帖子的 JSON 负载时，我在 actions_summary 或 post_action_users JSON 负载中都没有看到任何指示。

例如，这个帖子 有很多回复和点赞，但是当我通过浏览器查询它时 https://discuss.blues.io/post_action_users.json?id=31&post_action_type_id=2，我得到的回应是 {"post_action_users":[]}。

也许 API 已经改变了？或者我查询的东西不对。非常感谢您的帮助。

另外还有一个后续问题：是否可以设置一个 webhook 来通知我用户点赞帖子时，并能识别出用户和帖子？我们希望为分析目的捕获这些信息。

谢谢！

你好 Paige！

ID 为 31 的帖子是一个用于全局置顶的小帖子操作（即 Post.find(31).action_code == 'pinned_globally.enabled'），这些帖子不能像普通帖子一样进行交互，因此无法点赞。

该主题中只有一个普通帖子，但它也没有点赞。

试试帖子 33 - 那个帖子有赞，你可以在这里看到它们的序列化：

https://discuss.blues.io/post_action_users.json?id=33&post_action_type_id=2

您好，Leonardo：

非常感谢您提供关于不同帖子类型的信息，这些信息很有用。

感谢您的回复。

此致，
Paige
