通过Open Graph API发布时,不会呈现Facebook wallpost图像

Question

当墙贴通过Open Graph API制作时,需要一种方法让Facebook在墙柱中渲染图像.

当我将这个链接复制并粘贴到facebook.com上的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,使用下面的代码,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')

如何使用Facebook API在我的留言板中嵌入图像？

Answer 1

使用该link字段而不是message通过附件的字段

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)
