from lxml import etreefrom concurrent.futures import ThreadPoolExecutorfrom elasticsearch import Elasticsearchfrom elasticsearch import helpersimport requestsheaders = {    'user-agent': 'ua'}es = Elasticsearch()if not es.indices.exists(index='car'):    es.indices.create(index='car', mappings={        'properties': {            'url': {                'type': 'text'            },            'img': {                'type': 'text'            },            'title': {                'type': 'text'            },            'desc': {                'type': 'text'            }        }    })def task(url,page):    res = requests.get(url, headers)    text = res.text    tree = etree.HTML(text)    ul_list = tree.xpath('//ul[@class="article"]')    actions = []    for ul in ul_list:        li_list = ul.xpath('./li')        for li in li_list:            url = li.xpath('./a/@href'),            img = li.xpath('./a/div/img/@src'),            desc = li.xpath('./a/p/text()'),            title = li.xpath('./a/h4/text()')            if title:                doc = {                    '_index': 'car',                    'url': f'https:{url[0][0]}',                    'img': img[0][0],                    'desc': desc[0][0],                    'title': title[0],                }                actions.append(doc)    helpers.bulk(es, actions=actions)    print(f'第{page}页完成！')def main():    with ThreadPoolExecutor() as pool:        for i in range(1, 11):            url = f'https://www.autohome.com.cn/all/{i}/'            pool.submit(task, url=url,page=i)if __name__ == '__main__':    main()

视图函数
