數(shù)據(jù)解析陷阱：漏了追評，商家差評預警漏了 30% 的差評
系統(tǒng)上線后第二周，商家反饋：“昨天的 12 條差評，系統(tǒng)只預警了 8 條！” 排查發(fā)現(xiàn)，京東評論的返回結(jié)果藏著 “雙字段陷阱”——主評存在comments字段，追評（追加評論）存在after_comments字段，我只解析了comments，完全漏掉了追評里的差評：比如用戶買了商品 3 天后追加的 “質(zhì)量差，掉漆”，系統(tǒng)沒抓到，導致商家沒及時回復，店鋪動態(tài)評分掉了 0.2 分。

更坑的是，帶圖評論的圖片 URL 藏在images的url字段里，且部分追評的images是嵌套結(jié)構(gòu)，直接取值會報 KeyError；另外京東會對用戶昵稱脫敏（比如 “張 **”），如果直接展示會出現(xiàn)亂碼。我連夜重寫的評論解析函數(shù)，專門整合主評、追評、帶圖評論和情感判斷：
