javascript - Facebook Comments.Create 回调中的 ID 值

Question

根据 the Facebook documentation , comment.create 回调包含 Comment ID 属性:

{
  href: "",         /* Open Graph URL of the Comment Plugin */
  commentID: "",    /* The commentID of the new comment */
}

但是我看到回调包含一个公共(public) ID 属性，该属性在评论中不会改变。例如，当我调试回调时，我得到一个 commentID 值为 "10150259852273822"，但该页面上留下的任何评论的值都没有改变。下面是来自 Graph API 的评论示例，注意 ID 在多个评论中是相同的，但它附加了一个似乎实际上是标识符的 "_XXXX" 数字。

 {
    "id": "10150259852273822_17973898",
    "from": {
       "name": "XXXXXX",
       "id": "XXXXX"
    },
    "message": "newest comment",
    "created_time": "2011-08-24T19:24:02+0000"
 },
 {
    "id": "**10150259852273822**_17973932",
    "from": {
       "name": "XXXXX",
       "id": "XXXXX"
    },
    "message": "brand newest comment.",
    "created_time": "2011-08-24T19:25:40+0000"
 }

有谁知道如何通过 comment.create 事件获得完整的标识符？或者是否有另一个字段可用于预测 commonid_commentID 格式？

回调中的评论 ID 实际上是“post_fbid”。以下是获取评论(以及与之相关的数据)的方法:

FB.Event.subscribe('comment.create', function(response) {
    var commentQuery = FB.Data.query("SELECT text, fromid FROM comment WHERE post_fbid='"+response.commentID+"' AND object_id IN (SELECT comments_fbid FROM link_stat WHERE url='"+response.href+"')");
    var userQuery = FB.Data.query("SELECT name, uid FROM user WHERE uid in (select fromid from {0})", commentQuery);

    FB.Data.waitOn([commentQuery, userQuery], function() {
        // Do whatever you want with the data
        console.log(commentQuery.value[0].text);
        console.log(userQuery.value[0].name)
        console.log(userQuery.value[0].uid);
    });
});
