javascript - Facebook Comments中的ID值。创建回调

根据the Facebook documentation，comment.create回调包含一个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，该属性在注释之间不会发生变化。例如，当我调试回调时，我得到的commentID值为"10150259852273822"，但是该页面上留下的任何注释的值都不会改变。以下是来自Graph API的注释示例，请注意，多个注释之间的ID相同，但后面附加了一个"_XXXX"数字，该数字实际上是标识符。

 {
    "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"
 }

有谁知道您实际上如何通过comment.create事件获取完整标识符？还是有另一个字段可用于预测commonid_commentID格式？

最佳答案

回调中的注释ID实际上是“post_fbid”。
这是获取注释(以及与之关联的数据)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);
    });
});
