如何用python下载美女图片?（python3下载图片）

然后在网页中点击右键选择审查元素，然后将选项选到下图所示位置

右键刷新页面，出现下图

选第一项，右边出现一些信息，留着有用，可以先复制下来，如下的项目

'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',    'Accept-Encoding':'gzip, deflate',    'Accept-Language':'zh-CN,zh;q=0.9',    'Cache-Control':'max-age=0',    'Connection':'keep-alive',    'Cookie':'__guid=93692315.2789414934844540000.1575542378114.0908; Hm_lvt_19d597dda6fff717a20d276fa907bd17=1575376217,1575542380; monitor_count=27; Hm_lpvt_19d597dda6fff717a20d276fa907bd17=1575543370',    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36'

每个：两边的字符串原本是没有单引号的，是后加的。

之后点击查看源码，发现

每个图片的网址如上图红色框框所示，之后我们只要从网页中提取出这个网址，然后访问，就可以下载图片了。

提取网址的代码如下：

 list = []  def zhuye(aurl):     data= requests.get(aurl, headers=headers)     data.raise_for_status()     data.encoding = data.apparent_encoding     soup = BeautifulSoup(data.text, 'lxml')     imgs = soup.select('body > div.wrap > div.TypeList > ul > li> a')      for img in imgs:         photo = img.get('href')         list.append(photo)         print(photo)

先设置个list列表用于存储网址，然后定义一个函数，参数为main主函数里传入的初始网址，然后调用requests的get方法来获取网址的源代码，接着用BeautifulSoup库解析，查找对应的网址（如下图右键单击蓝色的网址选择copy，第二项copy selecter，如：‘body > div.wrap > div.TypeList > ul > li:nth-child(2) > a’，把倒数第二项改下‘body > div.wrap > div.TypeList > ul > li > a’，便如上图代码，接着从中用BeautifulSoup的get方法提取出网络地址，存储到list中）。

之后依然是解析网址，下载存储图片，就不一一详细说明了。

全部源码如下：

当然这只是下载每一个网址中的首长图片，后续的图片因为时间关系就不下了。
