采集数据，怎样获得网页的token

Question

打开网页（简称网页A）：http://www.iwencai.com/stockpick/search?typed=0&preParams=&ts=1&f=1&qs=result_original&selfsectsn=&querytype=&searchfilter=&tid=stockpick&w=%E6%A6%82%E5%BF%B5%E6%9D%BF%E5%9D%97%EF%BC%8C%E5%9F%8E%E5%B8%82&queryarea=

点击数据表格下部的分页标签，抓包发现数据接口的地址为：http://www.iwencai.com/stockpick/cache?token=74c27554e5ea5813bc2666c24dfda4ef&p=2&perpage=10&showType=[%22%22,%22%22,%22onTable%22,%22onTable%22,%22onTable%22,%22onTable%22,%22onTable%22,%22onTable%22,%22onTable%22,%22onTable%22]

对该网页采集数据，但每次重新打开网页A时都会重新生成token。

请问怎样从网页A中获得该token？

token就在你的
http://www.iwencai.com/stockpick/search?typed=1&preParams=&ts=1&f=3&qs=pc_%7Esoniu%7Estock%7Estock%7Ehistory%7Equery&selfsectsn=&querytype=&searchfilter=&tid=stockpick&w=%E6%A6%82%E5%BF%B5%E6%9D%BF%E5%9D%97%EF%BC%8C%E5%9F%8E%E5%B8%82
这个页面里面啊，查看源代码就看到了，所以你要先请求一次这个页面获取token再替换接口api中的token进行后续的捉取，里面存在2个token的地方，前后截取一处的token就行

/*将问句搜索返回的json数据传入到JS中*/
var allResult = {"......................,"token":"ead14eda7b6978a3754f9bec95f2e1d3","perpage":10,..............

var xgblocksResult = {"blocks":[{"lazy_load":1,"T_id":20,"P_id":24,"title":"\u878d\u8d44\u878d\u5238\u4f59\u989d\u76f8\u5173\u5206\u6790","url":"\/xgblock\/block-detail?token=ead14eda7b6978a3754f9bec95f2e1d3&info=&querytype=stockpick&pid=24&tid=20"}],"global":{"pidRefTid":{"24":20},"configTag":"24"}};
