11.校验IP-v6地址
(([0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,7}:|([0-9a-fA-F]{1,6}:[0-9a-fA-F]{1,5}(:[0-9a-fA-F]{1,4}){1,2}|([0-9a-fA-F]{1,4}(:[0-9a-fA-F]{1,3}|([0-9a-fA-F]{1,3}(:[0-9a-fA-F]{1,2}(:[0-9a-fA-F]{1,5}|[0-9a-fA-F]{1,4}:((:[0-9a-fA-F]{1,6})|:((:[0-9a-fA-F]{1,7}|:)|fe80:(:[0-9a-fA-F]{0,4}){0,4}%[0-9a-zA-Z]{1,}|::(ffff(:0{1,1}:){0,1}((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9])|([0-9a-fA-F]{1,4}:((25[0-5]|(2[0-4]|1{0,1}[0-9]))
12.检查URL前缀
if (!s.match(/^[a-zA-Z]+:\\/\\//)){ s = 'http://' + s; }
^(f|ht){1}(tp|tps):\\/\\/([\\w-]+\\.)+[\\w-]+(\\/[\\w- ./?%&=]*)?
(<a\\s*(?!.*\\brel=)[^>]*)(href="https?:\\/\\/)((?!(?:(?:www\\.)?'.implode('|(?:www\\.)?',$follow_list).'))[^"]+)"((?!.*\\brel=) [^>]*)(?:[^>]*)>
