[Python知识库]Python实现【亚马逊商品】数据采集

前言

亚马逊公司，是美国最大的一家网络电子商务公司，位于华盛顿州的西雅图
是网络上最早开始经营电子商务的公司之一，亚马逊成立于1994年
今天教大家用Python批量采集亚马逊平台商品数据
地址：https://www.amazon.cn/

分析网站数据，找到url地址

1.按F12，打开开发者工具，并刷新网站
2.点击搜索，输入数据关键词
3.找到数据所在url地址

开始我们的代码

1. 发送请求

headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',

}

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

print(response)

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

with open('亚马逊.csv', mode='a', encoding='utf-8', newline='') as f:
    csv_writer = csv.writer(f)
    csv_writer.writerow([title, price, img_url, link])

5. 翻页

for page in range(1, 401):
    url = f'https://www.amazon.cn/s?i=computers&rh=n%3A106200071&fs=true&page={page}&qid=1645537294&ref=sr_pg_3'

这样完整的数据就采集出来了：完整源码
