使用python从多个媒体中检索Instagram评论

标签: python api comments instagram

我使用this unofficial API在特定媒体下检索评论。 我稍微修改了代码,因此我不必每次都更改媒体ID以获取其评论,因此我的想法基本上是包含这样的媒体列表:

media_list = [media_id1, media_id2, ... ]

并将其传递给一个周期。我的最终输出将是这样的文本文件:

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,然后它为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?我显然不是程序员,我对python的能力和经验非常低,并且把它作为一种爱好学习,所以请原谅我,如果我犯了一些明显的错误,我仍然无法注意到 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: ...
