1. 发送请求

}url = 'https://www.amazon.cn/s?rh=n%3A106200071&fs=true&ref=lp_106200071_sar'response = requests.get(url=url, headers=headers)
2. 获取数据
返回结果为<Response [200]>: 请求成功
把结果封装
data_html = response.text
3. 解析数据
selector = parsel.Selector(data_html)
divs = selector.css('.a-section.a-spacing-base')
for div in divs:# ::text: 提取到标签文本内容title = div.css('.a-size-base-plus.a-color-base.a-text-normal::text').get()price = div.css('.a-size-base.a-link-normal.s-underline-text.s-underline-link-text.s-link-style.a-text-normal .a-price .a-offscreen::text').get()img_url = div.css('.a-section.aok-relative.s-image-square-aspect .s-image::attr(src)').get()link = div.css('.a-link-normal.s-no-outline::attr(href)').get()print(title, price, img_url, link)
4. 保存数据
5. 翻页
