Question

我正在尝试获取有关Facebook帖子的评论和评论的用户详细信息。我正在使用python facebook-sdk包。代码如下。

import facebook as fi
import json

graph = fi.GraphAPI('Access Token')
data = json.dumps(graph.get_object('DSIfootcandy/posts'))

从上面，我得到了一个高度嵌套的json。在这里，我将只为fb中的一个帖子添加一个json字符串。

}

现在我需要将这些数据放入数据框中，如下所示（无需全部获取）。

item | Like_id |Like_username | comments_userid |comments_username|comment(msg)|
-----+---------+--------------+-----------------+-----------------+------------+
Bag  |   45546 |  noel        | 641             | James           | nice work  |
-----+---------+--------------+-----------------+-----------------+------------+

任何帮助都会受到高度赞赏。

不完全符合您的预期格式，但这是制作解决方案：

import pandas

DictionaryObject_as_List = str(mydict).replace("{","").replace("}","").replace("[","").replace("]","").split(",")

newlist = []

for row in DictionaryObject_as_List :
    row = row.replace('https://',' ').split(":")
    exec('newlist.append ( ' + "[" + " , ".join(row)+"]" + ')')

DataFrame_Object = pandas.DataFrame(newlist)

print DataFrame_Object

将深层嵌套的json从facebook转换为python中的dataframe
