知乎登录时返回403错误码，登录好像做得更复杂了

爬子标签新闻时，我每次返回的json数据基本都是一样的，你有遇到这种问题吗？

这个是为什么呀

可以和您交流一下知乎爬虫的相关问题嘛

启动爬虫后，爬取了一部分文章就会报错，是因为传入参数不正确的原因吗

能帮看看吗
DEBUG: Retrying <GET https://www.toutiao.com via http://localhost:8050/render.html> (failed 1 times): Connection was refused by other side: 10061: 由于目标计算机积极拒绝，无法连接。.

你好，请问爬取大众点评评论的时候总是跳转到验证中心或者显示页面不存在，这个问题该怎么解决呢？
