}
url = 'https://www.tripadvisor.com/Restaurants-g188590-Amsterdam_North_Holland_Province.html'
response = requests.get(url, headers=headers)

2. 获取数据(网页源代码)

html_data = response.text

3. 解析数据(提取我们想要的数据内容 详情页链接)

selector = parsel.Selector(html_data)
# 提取标签的属性内容 ::attr(href) 链接
link_list = selector.css('.bHGqj.Cj.b::attr(href)').getall()
for link in link_list:
   link = 'https://www.tripadvisor.com/' + link

4. 发送请求(访问所有的详情页链接) 获取数据

detail_html = requests.get(link, headers=headers).text

5. 解析数据

detail_selector = parsel.Selector(detail_html)
store_name = detail_selector.css('.fHibz::text').get()
comment_count = detail_selector.css('.eSAOV.H3:nth-child(2) .eBTWs::text').get()
address = detail_selector.css('.eSAOV.H3:nth-child(3) .dyeJW.dUpPX:nth-child(1) .fhGHT::text').get()
city = detail_selector.css('.breadcrumbs li:nth-child(4) span::text').get()
phone = detail_selector.css('.eSAOV.H3:nth-child(3) .dyeJW.dUpPX:nth-child(2) .fhGHT a::text').get()
score = detail_selector.css('.eEwDq .fdsdx::text').get()
website = re.findall(',"website":"(http.*?)"', detail_html)[0]
print(store_name, comment_count, city, address, phone, score, link, website)

6.保存数据

with open('tripadvisor.csv', mode='a', newline='', encoding='utf-8') as f:
   csv_writer = csv.writer(f)
   csv_writer.writerow([store_name, comment_count, city, address, phone, score, link, website])

7.得到数据
