python爬虫获取携程旅游景点评分和评论

写在前面：酒店和旅游景点方式不同，不能用我的写法，如果获取酒店数据请参考：https://blog.csdn.net/qq_34774456/article/details/89885296

旅游景点代码（地址要用手机版的携程搜自己想搜的景点）：

中间一大堆replace是携程json很多不规则的地方需要替换想data:"{}"这种结构

发现只能搜前3000条，后面就搜不到了，不知道什么情况

playod来源是Request Payload里的参数:

还有综合评价和好评差评是分开的

用网页模拟点击：

这个参数0是综合 -11是好评 -12差评
