Facebook实时更新：订阅一个页面 [英] Facebook realtime updates: Subscribing to a page

问题描述

任何人尝试订阅一个页面进行实时更新？例如，当网页的资讯提供下方显示新的墙贴时，我想收到通知。

Facebook文档说这是可能的，但从来没有见过任何人这样做。

解决方案

你需要获取page_accesstoken，然后添加应用程序作为选项卡。您可以通过
获取用户访问令牌的admin，范围= manage_pages
一旦您获得用户访问令牌，您可以查询我/帐户。它将显示类似于

  {
category：Community，
name page name，
access_token：xxxxx，
id：1111111134678999，
perms：[
ADMINISTER，
 EDIT_PROFILE，
CREATE_CONTENT，
MODERATE_CONTENT，
CREATE_ADS，
BASIC_ADMIN
] 
} 
  

该xxx将是页面访问令牌，页面访问令牌必须将您的应用程序添加为选项卡。你可以通过

https://graph.facebook.com/PAGEID/tabs?app_id=APPID&method=POST&access_token=xxx

现在，只要页面发生变化，您将收到一个请求到您的回调URL。请求看起来像。

  {
object：page，
entry ：[
 {
id：408518775908252，
时间：1360643280，
更改：[
 {
 ：feed，
value：{
item：like，
verb：add，
user_id：5900878 
} 
} 
] 
} 
] 
} 
  

希望这有帮助。

Anyone tried subscribing to a page for real-time updates? I would like to get notified when a new wall post appears under a page's feed for example.

The Facebook documentation says this is possible but have never seen anyone accomplished this before.

解决方案

You need to get the page_accesstoken and then add the app as a tab. You can do this by getting the user access token of the admin with scope=manage_pages once you get the user access token you can query me/accounts. It will display something like

  {
      "category": "Community", 
      "name": "page name", 
      "access_token": "xxxxx", 
      "id": "1111111134678999", 
      "perms": [
        "ADMINISTER", 
        "EDIT_PROFILE", 
        "CREATE_CONTENT", 
        "MODERATE_CONTENT", 
        "CREATE_ADS", 
        "BASIC_ADMIN"
      ]
    }

That xxx would be the page access token, with the page access token you have to add your app as a tab. You can do that by

https://graph.facebook.com/PAGEID/tabs?app_id=APPID&method=POST&access_token=xxx

And now you will get a request to your callback url whenever there is a change in the page. The request looks something like.

{
    "object": "page",
    "entry": [
        {
            "id": "408518775908252",
            "time": 1360643280,
            "changes": [
                {
                    "field": "feed",
                    "value": {
                        "item": "like",
                        "verb": "add",
                        "user_id": 5900878
                    }
                }
            ]
        }
    ]
}

Hope this helps.
