在使用 facepy 包从一个组中获取帖子后，我注意到一些图片正在被检索，而另一些则没有。我知道有些帖子没有附加任何图片，但我发现其他帖子在数据字典中没有“图片”键条目，但是当我在浏览器中打开帖子时，我可以看到实际上附加了图像到帖子。这是我正在使用的代码。

from facepy import GraphAPI

ACCESS_TOKEN = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
graph = GraphAPI(ACCESS_TOKEN)
groupIDs = (['xxxxxxxxxxxxxxx'])

groupData = graph.get(groupIDs[0] + "/feed", page=False, retry=3, limit=600)
dataDict = groupData['data']

for data in dataDict:
    try:
        picture = property['picture']
    except Exception as e:
        #no picture available
        continue

知道如何获取这些图像吗？

UPD：无论如何，您都会从json. 尝试这个：

graph = GraphAPI(access_token)
group_id = "xxxxxxxxxxxxxxx"
graph.fql( SELECT post_id, message, attachment FROM stream WHERE source_id=group_id)

此查询返回以下数据，fullsize_src图片的链接在哪里： 

{
  "data": [
    {
      "message": "test...",
      "post_id": "348119228599690_933534210058186",
      "updated_time": 1453685624,
