Question

脚本应该监视一个Facebook帖子。如果有人对帖子发表评论，则脚本将拍摄该人的个人资料图片，并用另一张图片覆盖该图片，然后将其发布为对评论的回复。但是我得到了'from'的KeyError信息。

Pycharm的内容如下：

文件   “ C：/用户/用户/桌面/facebook-bot-autoresponder-master/autoresponder.py”，   162行，在       monitor_fb_comments（）文件“ C：/Users/user/Desktop/facebook-bot-autoresponder-master/autoresponder.py”，   第118行，在monitor_fb_comments中       comment_on_comment（图形，注释）文件“ C：/Users/user/Desktop/facebook-bot-autoresponder-master/autoresponder.py”，   第57行，在comment_on_comment中       comment_from_name = comment ['from'] ['name'] KeyError：'from'

以退出代码1完成的过程

获取KeyError：此Facebook脚本的'from'错误？
