php 如何获取这个携程页面的数据

Question

携程目标URL：https://piao.ctrip.com/ticket...想要获取门票页面的景点图片URL直接查看源代码只能获取到第一张的景点图片自己看下了，应该是请求这个url的https://sec-m.ctrip.com/restapi/soa2/10131/json/ViewSpotImages?_fxpcqlniredt=09031037311838329819但是请求参数较多如下：{"id":49894,"imgsizes":["C_500_280","C_73_43"],"prdid":90971,"contentType":"json","head":{"appid":"100013776","cid":"09031037311838329819","ctok":"","cver":"1.0","lang":"01","sid":"8888","syscode":"09","auth":"","extension":[]},"ver":"7.10.3.0319180000","pageid":10650000804}不知道如何找这个请求参数的规律
