上面这个COOKIES 用正则匹配_tb_token_=obU42Ba54Lp;这个值,
用这个表达式直接把后面一长串都给匹配上了,
然后变成这样了_tb_token_=obU42Ba54Lp; v=0; cookie32=d2874877ef98c1c142fc1ddff656fb50; cookie31=MTA5NzY3MjEsa2lzdGVhcixqc3djQDE2My5jb20sbnVsbA%3D%3D; alimamapwag=TW96aWxsYS80LjAgKGNvbXBhdGlibGU7IE1TSUUgNy4wOyBXaW5kb3dzIE5UIDYuMjsgV09XNjQ7IFRyaWRlbnQvNy4wOyAuTkVUNC4wQzsgLk5FVDQuMEU7IC5ORVQgQ0xSIDIuMC41MDcyNzsgLk5FVCBDTFIgMy4wLjMwNzI5OyAuTkVUIENMUiAzLjUuMzA3Mjkp; login=W5iHLLyFOGW7aA%3D%3D; alimamapw=DggWRANZRTAHBVcABwAEBQRbUFZcAgVeB1oEBwAHU1AEA1INVAUAUg%3D%3D
我知道用\W可以搞定,但是我非要用.*的话应该怎么弄?就匹配到第一个;?

1.findall,search皆可，注意方法返回的值
2.pattern写法，注意贪婪和非贪婪匹配
3.HEREDOC是不错的选择，字符串长的时候
