最近试了一下，原来的版本里正则式匹配不了图片链接了，重新改了一下import requests
import re
import os
import easygui as g

headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3314.0 Safari/537.36 SE 2.X MetaSr 1.0'}
req = requests.get(url, headers=headers)
return req
def get_img_url(url1, url2): #图片地址
headers = {
'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3314.0 Safari/537.36 SE 2.X MetaSr 1.0',
'referer':url2
