我在 Facebook 上发布了至少 4,000 条已确认的公众评论。但我不能得到超过 980 个。

每次，一旦我清除 900，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：

    except:

        next = decoded['paging']['next']

    for d in comments:

    x = x + 1

我很肯定我已经收到了超过 1000 条公众评论。该帖子总共有 4780 条评论——我认为其中 3800 条不太可能被标记为私人评论。

有人遇到过这种情况么？我在做一些明显的错误吗？

我发现了问题。令人惊讶的是，问一群其他人如何突然暴露了手掌。

我有这个：

    theFeedUrl = nexturl + "&" + access_token

它应该是：

    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 个不带正确 URL 的事实使情况更加复杂。
