def getdata(url):
    html=requests.get(url).text
    # print(html)
    doc=etree.HTML(html)#構造xpath的解析對象
    contents=doc.xpath('//*[@class="cf"]/li')
    # print(contents)
    for content in contents:
        links=content.xpath('h2/a/@href')
        for link in links:
            hurl="https:"+link#小說某一章的網址
            html=requests.get(hurl).text#獲取到源代碼
            doc=etree.HTML(html)#構造xpath解析對象
            title=doc.xpath('//*[@class="text-wrap"]/div/div[1]/h3/span[1]/text()')
            content=doc.xpath('//*[@class="read-content j_readContent"]/p/text()')
            with open('novel/%s.txt'%title[0],mode='w',encoding='utf-8') as f:
                for abd in content:
                    f.write(abd)

函數功能比較簡單，所以就沒有對其中的保存小說的函數進行封裝，有興趣的可以自己嘗試一下。
