从Instagram API接收的媒体中提取标签

Question

这是来自GitHub上python-instagram文档的一个例子：

from instagram.client import InstagramAPI

access_token = "YOUR_ACCESS_TOKEN"
api = InstagramAPI(access_token=access_token)
recent_media, next_ = api.user_recent_media(user_id="userid", count=10)
for media in recent_media:
   print media.caption.text   # it gets caption text from each media

但是，当我尝试这个（只有最后一行改动了）：

from instagram.client import InstagramAPI

access_token = "YOUR_ACCESS_TOKEN"
api = InstagramAPI(access_token=access_token)
recent_media, next_ = api.user_recent_media(user_id="userid", count=10)
for media in recent_media:
   print media.tags  # attempt to get tags associated with each media

它显示媒体没有“tags”这个属性。我觉得从Instagram的API返回的内容里应该有“tags”这个键。

我漏掉了什么呢？怎么才能获取媒体的标签呢？

Answer 1

首先，你要确保有一个标签属性。就像这样：

from instagram.client import InstagramAPI

access_token = "YOUR_ACCESS_TOKEN"
api = InstagramAPI(access_token=access_token)
recent_media, next_ = api.user_recent_media(user_id="userid", count=10)
for media in recent_media:
    if hasattr(media, 'tags'):
        print media.tags  # attempt to get tags associated with each media
    else:
        # you can check if there is tags attribute through this line
        print 'all the attributes of media are: ', repr(dir(media))
