## 分析网页 ##

1、查看图片地址

## 代码实现 ##

import requests
    import parsel
    url = 'https://bcy.net/coser/toppost100'
    response = requests.get(url=url, headers=headers)
    selector = parsel.Selector(response.text)
    urls = selector.css('.rank-index-box .rank-cos-top img::attr(src)').getall()
    titles = selector.css('.rank-index-box .rank-cos-avatar-box p::text').getall()
    lis = zip(urls, titles)
    for i in lis:
        img_url = i[0]
        title = i[1]
        response_2 = requests.get(url=img_url, headers=headers)
        path = 'D:\\python\\demo\\cos小姐姐\\img\\' + title + '.jpg'
        with open(path, mode='wb') as f:
            f.write(response_2.content)
            print(img_url)

图片数据是爬取下来了，但是保存数据后发现，仅仅只有20张图片，这根本不是我想要的~

所以要重新分析网页了~看一下是否有接口数据  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlaTM0Nzc5NTc5MA_size_16_color_FFFFFF_t_70_pic_center 10]  
我清空所有加载出来的数据，下拉的时候，然后出现一个神秘地址，点击去一看，果然是接口数据。为了保证准确性，咱们可以多往下翻翻

果然~~~

通过链接对比，发现接口数据的参数P是改变的，等同于页数编码，1就是对应的前20张图片数据
