1、安装scrapy
2、创建爬虫项目 scrapy startproject test_scrapy 3、创建quotes_spider.py文件 4、复制下面代码到quotes_spider.py文件 import scrapy #导入模块 #编写QuotesSpider类
class QuotesSpider(scrapy.Spider):
name = "quotes"
#爬取网站地址
start_urls = [
'http://quotes.toscrape.com/tag/humor/',
]
def parse(self, response): #定义解析方法
for quote in response.css('div.quote'):
#解析class="quote"的div
#采用字典记录,爬取内容部分定义
yield {
'text': quote.css('span.text::text').extract_first(),
'author': quote.xpath('span/small/text()').extract_first(),
}
#下一页地址
next_page = response.css('li.next a::attr("href")').extract_first()
if next_page is not None:
yield response.follow(next_page, self.parse)
5、cd test_scrapy 到quotes_spider.py文件目录
6、运行scrapy runspider quotes_spider.py -o quotes.json命令
可看到目录下多了quotes.json文件
打开quotes文件可看到[
