当墙贴是通过 Open Graph API 创建时,Facebook 需要一种方法来呈现墙贴中的图像。
当我将此链接复制并粘贴到 facebook.com 的 Facebook 用户界面并以这种方式发布时,墙贴最终看起来像这样:
但是,当我尝试使用 Facebook Python 库以编程方式访问我的墙时,使用以下代码,图像不会呈现:
graph = GraphAPI(valid_access_token)
graph.put_wall_post(message='https://s3.amazonaws.com/dotellapptest/review_photos/enlarged/811..OJUzXI76Rw6J2Zj_vZyWNw.png')
产生这个:
如何使用 Facebook API 将图片嵌入到我的墙帖中?
最佳答案
通过附件使用 link
字段而不是 message
字段
def put_wall_post(self, message, attachment={}, profile_id="me"):
"""Writes a wall post to the given profile's wall.
We default to writing to the authenticated user's wall if no
profile_id is specified.
attachment adds a structured attachment to the status message
being posted to the Wall. It should be a dictionary of the form:
{"name": "Link name"
"link": "http://www.example.com/",
"caption": "{*actor*} posted a new review",
"description": "This is a longer description of the attachment",
"picture": "http://www.example.com/thumbnail.jpg"}
"""
return self.put_object(profile_id, "feed", message=message,
**attachment)
