def?parse(self,pageUrl,htmlCont): ????if?pageUrl?is?None?or?htmlCont?is?None: ????????return ????soup?=?BeautifulSoup(htmlCont,'html_parser',from_encoding='utf-8') ????new_urls?=?self._get_new_urls(pageUrl,soup) ????new_data?=?self._get_new_data(pageUrl,soup) ????return?new_urls,?new_data 這個(gè)方法里 soup?=?BeautifulSoup(htmlCont,'html_parser',from_encoding='utf-8')這一句代碼執(zhí)行完，?parse?方法?就直接返回了，導(dǎo)致new_urls?，new_data?都沒有值，main模塊中的的try就出現(xiàn)異常，然后就退出了，是哪個(gè)環(huán)節(jié)出錯(cuò)導(dǎo)致的呀，求大神指點(diǎn)
