来八八美团页面的防采集方法

Question

这与防采集无关，而与他用的 UI 有关
data-poi 的值是（url编码到达 js 时已还原）
[{"shopid":566878,"name":"\u80e4\u9686\u6c47","address":"\u6c5f\u5e72\u533a\u65b0\u5858\u8def\u676d\u6d77\u8def238\u53f7\uff08\u68ee\u79be\u5e7f\u573a\uff09","range":"\u94b1\u6c5f\u65b0\u57ce","rangeid":5455,"disid":58,"disname":"\u6c5f\u5e72\u533a","dpshopid":0,"mapurl":"","trafficinfo":"","phone":"0571-86963688\/86963788","latlng":"[30.253548,120.206872]","city":50,"url":"","poiid":6307803,"poilevel":{"avgscore":"4.8","fbcount":1471},"cityname":"\u676d\u5dde","status":0,"subwayname":"","subwaydis":0,"subwayslug":"","appointmentDay":0}]json 解码后是 Array

Answer 1

只是json后的一种数据格式，你可以在json解码转过来就可以了，然后页面时采用的ajax进行局部数据输出的，当你只是采集的时候无法获取到对应的文字内容很正常。

Answer 2

再仔细分析了下他的页面代码，里面用JS调用的combo文件起到了解释的作用。这是YUI框架的原因啊
