python3 beautifulsoup解析网页下载图片

今天有朋友叫我解析以下img的url，然后下载图片，这里我分享一下我的下载过程。

import urllib.request
from bs4 import BeautifulSoup
#获取页面信息
def getHtml(url):
    html = urllib.request.urlopen(url).read()
    return html


url='https://partner.googleadservices.com/gampad/ads?gct=-hB1lC5stH0KcooYbypjCAIQFEoAWICAgKDn4PjoxwG4Aafg8JuDBNICCWltYWdlL2dpZvACrAL4AvoBkAMAyAOsAtAD-gHwAwLKBSJodHRwczovL3d3dy5hcm1hemVtcGIuY29tLmJyLz9HRVBC6gYAsgECGAHKAQJAARiLy4ryBSgAMIvnv_kFOABYAWoGX2JsYW5rcP_ehfIF&iu=95377733&gdfp_req=1&height=250&width=300&impl=ifr'

html=getHtml(url)

bs = BeautifulSoup(html,"html.parser") # 缩进格式

for item in bs.find_all("img"): 
    print(item)
    img_path=item.get('src')
    if(img_path.startswith('https://')):
        urllib.request.urlretrieve(img_path, 'img.jpg')

这是演示代码，读者可以根据需要进行修改。
