Question

我的Facebook帖子至少有4,000条公开评论。但我不能得到超过980个。

每次，当我清除900时，我都会收到此错误：

Traceback (most recent call last):
    File "fb_pcf_temp.py", line 41, in <module>
    next = decoded['paging']['next']
KeyError: 'next'

我的代码是：

while x < 40:
    decoded = getmore(next)
    try:
        comments = decoded['comments']['data']
        next = decoded['comments']['paging']['next']

    except:
        comments = decoded['data']
        next = decoded['paging']['next']

    for d in comments:
        print '%s\t%s\t%s\t%s\t"%s"' % (d['created_time'],d['like_count'],d['from']['name'],d['from']['id'],d['message'])
    x = x + 1

我很肯定我已经收到了1000多条公众意见。该帖子总共有4780条评论 - 我认为不太可能有3800条评论是私密的。

还有其他人遇到过这个吗？我做了一件明显不对的事吗？

Answer 1

我发现了问题。令人惊讶的是如何让一群其他人突然露出脸庞。

我有这个：

    theFeedUrl = nexturl + "&" + access_token

应该是：

    theFeedUrl = nexturl + "&access_token=" + access_token

愚蠢的粗心错误，由于某种原因，Facebook让我请求前1000个正确的URL，这一事实进一步加剧了这一点。

无法通过API对过去的1000条评论进行分页
