我使用this unofficial API来检索特定媒体下的评论。我稍微修改了代码,这样我就不必每次都更改媒体id来获得它的评论,所以我的想法基本上是包括一个如下所示的媒体列表:
media_list = [media_id1, media_id2, ... ]
并将其传递给一个循环。我的最终输出将是一个文本文件,如下所示:
media_id1
username1 comment1
username2 comment2
username3 comment3
media_id2
username1 comment1
...
这是我修改原始代码的方式:
for i in medialist:
comments = []
while has_more_comments:
_ = API.getMediaComments(i,max_id=max_id)
#comments' page come from older to newer, lets preserve desc order in full list
for c in reversed(API.LastJson['comments']):
comments.append(c)
has_more_comments = API.LastJson.get('has_more_comments',False)
#evaluate stop conditions
if count and len(comments)>=count:
comments = comments[:count]
#stop loop
has_more_comments = False
print "stopped by count"
#next page
if has_more_comments:
max_id = API.LastJson.get('next_max_id','')
time.sleep(2)
for c in comments:
username = c['user']['username']
text = c['text']
user = username.encode('utf-8')
txt = text.encode('utf-8')
print (i+"\n"+user+": "+txt+"\n")
我的问题是,我只从列表中的第一个media_id获得评论,然后它给我提供了其他媒体的空列表:
1412361909683907264
[{u'status': u'Active', u'user_id': xxx, u'created_at_utc': xxx, u'created_at': xxx, u'bit_flags': 0, u'comment_like_count': 1, u'did_report_as_spam': False, u'user': {u'username': u'xxx', u'profile_pic_url': u'xxx', u'profile_pic_id': u'xxx', u'full_name': u'xxx', u'pk': xxx, u'is_verified': False, u'is_private': True}, u'content_type': u'comment', u'text': u'When you eat pasta remember me \U0001f602\U0001f602\U0001f602\U0001f602\U0001f44d\U0001f3fb\U0001f4aa\U0001f3fc', u'pk': xxx, u'type': 0, u'has_liked_comment': False}]
1412360153562726838
[]
1412342538912059069
[]
1412336815465111851

问题出在哪里?我显然不是一个程序员,我对python的能力和经验都很低,只是把它当作一种爱好来学习,所以如果我犯了一些明显的错误,我仍然没有注意到,请原谅,谢谢!

我认为您需要在媒体列表中的第一项之后将has_more_comments
设置回True
。
for i in medialist: comments = [] has_more_comments = True while has_more_comments: ...
