看起来是你105行传入的response_first里面有execjs无法解析的字符, 还有下次写脚本尽量路径和文件名使用英文名

grekevin 发表于 2023-7-19 22:31

你把dcbb.js用记事本打开，另存为UTF-8格式

zyjsuper 发表于 2023-7-20 01:28

       response_first = self.session.get(self.article_info_url.format(article_id), headers=headers).content.decode()
打印下这个值看看，或者设置decode编码为utf8

sai609 发表于 2023-7-20 08:08

这是网络爬虫？？？

ciker_li 发表于 2023-7-20 09:45

dcbb.js发出来看看

白水饮 发表于 2023-7-20 10:21

js代码有问题

鹿鸣 发表于 2023-7-20 10:50

路径和文件名使用了中名吧

kof21411 发表于 2023-7-20 12:41

把dcbb.js里的中文注释全部去掉

magicianly 发表于 2023-7-20 13:33


如果各位的方法你试过，都没有解决，那么你可以把这里改一下，试一下
