使用facepy从帖子中获取“图片”

Question

在使用facepy软件包从小组中获取帖子后，我注意到正在检索某些图片，而另一些则没有。 我知道有些帖子没有附加图片，但是我发现其他一些在数据字典中没有“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有图片到职位。 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

关于如何获取这些图像的任何想法吗？

UPD：无论如何，您都从json接收数据。 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)

该查询返回以下数据，其中fullsize_src是图片的链接：

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