我正在编写一个从用户 Facebook 通知中收集信息的应用程序。使用Graph Explorer，我要求：

me/notifications?include_read=true

这会返回一堆数据。每个项目都是您在登录 Facebook 时会看到的通知项目。例如（ID/名称略有变化）：

{
  "id": "notif_630262196_168132987", 
  "from": {
    "name": "John Bloggs", 
    "id": "822724665"
  }, 
  "to": {
    "name": "Dermot Bloggs", 
    "id": "680265196"
  }, 
  "created_time": "2013-01-23T22:58:28+0000", 
  "updated_time": "2013-01-23T22:58:28+0000", 
  "title": "John Bloggs commented on your link: \"Goodbye Great Barrier Reef. Goodbye...\"", 
  "link": "http://www.facebook.com/<removed>/posts/330788937030559?comment_id=1702155", 
  "application": {
    "name": "Links", 
    "id": "2309869772"
  }, 
  "unread": 0, 
  "object": null
}

通知与评论有关，但如果“标题：”字段太长，则会被截断。

有没有一种干净的方法可以直接以编程方式访问评论，所以我可以获得所有文本，即使它是 1000 个字符的评论？

谢谢！:-)

You should be able to get the comment by parsing the link field and querying:

/330788937030559_1702155

or

/POSTID_COMMENTID

When I tested this on my account, I am getting a comments object in the returned data, with the full text of the comments. I've got most permissions enabled in my Graph API. I suspect adding read_stream to the permissions is what will give you this data.

你可以避免解析！我一直在对通知进行大量实验，并获得了我所谓的“源”对象（源对象是发出通知的 Facebook 图形对象）。不幸的是，我找不到任何关于这种机制究竟是如何工作的文档，但如果您的应用程序已被授予大量权限，那么"object"您发布的 JSON 中的字段null实际上将填充“源对象”。而不仅仅是"object" : null它看起来像这样：

"object": {
    "id": "587140489_588632201147717",

    }, 
    "comments": {
      "count": 0

  }

我希望比我更有知识的人能准确地告诉我们，我们需要什么权限才能看到这个字段被填充。我自己会弄清楚，但是权限太多，强制使用SUM(nCk(77,k),k,1,77)=151115727451828646838271可能的权限组合需要很长时间。
