東方財(cái)富網(wǎng)美股吧貼子數(shù)據(jù) 包含：瀏覽數(shù)佳谦、評(píng)論數(shù) 、帖子標(biāo)題 洪唐、帖子內(nèi)容 尺锚、回復(fù)人、 回復(fù)時(shí)間讶凉、 回復(fù)內(nèi)容http://guba.eastmoney.com/list,meigu.html

這個(gè)網(wǎng)站作為練習(xí)提升挺大的染乌，有很多小細(xì)節(jié)要摳，花了好多時(shí)間懂讯，還是沒(méi)搞完荷憋。目前能爬，但是有一些編碼和最后數(shù)據(jù)處理的問(wèn)題還沒(méi)解決褐望。不知為何勒庄。先交。
