python利用线程池快速下载某趣阁小说

1.首先我们先导入我们需要的包

import requests
from lxml import etree
import os
from concurrent.futures import ThreadPoolExecutor #线程池

1.然后从一本书中获取各个章节的链接

url = 'https://www.biquge9.com/book/3808/'
res = requests.get(url=url)
t = etree.HTML(res.text)
i = t.xpath('//div[@class="listmain"]/dl/dd/a/@href')
o = i[:10]
p = i[11:]
b = t.xpath('//div[@class="listmain"]/dl/span/dd/a/@href')
z = o + b + p
ur = []
for v in z:
    ur.append('https://www.biquge9.com' + v)

3.定义一个函数从章节链接中获取内容

def download(url,file):
    re = requests.get(url=url)
    re.encoding = 'utf-8'
    if not os.path.exists(file):
        os.mkdir(file)
    tr = etree.HTML(re.text)
    name = tr.xpath('//div[@class="book reader"]//div[@class="content"]/h1/text()')[0]

    path = file + '/' + name + '.txt'
    fp = open(path, 'w', encoding='utf-8')
    q = tr.xpath('//*[@id="chaptercontent"]/text()')
    for nei in q:
        fp.write(nei + '\n')
        print(name + '爬取成功')
    fp.close()

总体思路就这样，然后创建线程池快速爬取小说

下面这是源码

import requests
from lxml import etree
import time
import os
from concurrent.futures import ThreadPoolExecutor
def download(url,file):
    re = requests.get(url=url)
    re.encoding = 'utf-8'
    if not os.path.exists(file):
        os.mkdir(file)
    tr = etree.HTML(re.text)
    name = tr.xpath('//div[@class="book reader"]//div[@class="content"]/h1/text()')[0]

    path = file + '/' + name + '.txt'
    fp = open(path, 'w', encoding='utf-8')
    q = tr.xpath('//*[@id="chaptercontent"]/text()')
    for nei in q:
        fp.write(nei + '\n')
        print(name + '爬取成功')
    fp.close()
if __name__ == '__main__':
    '''获取章节内容url'''
    print('新笔趣阁的网址为：https://www.biquge9.com')
    url = str(input('请输入新笔趣阁中书的网址链接：'))
    file = input('请输入文件夹的名字：')
    # url = 'https://www.biquge9.com/book/3808/'
    res = requests.get(url=url)
    t = etree.HTML(res.text)
    i = t.xpath('//div[@class="listmain"]/dl/dd/a/@href')
    o = i[:10]
    p = i[11:]
    b = t.xpath('//div[@class="listmain"]/dl/span/dd/a/@href')
    z = o + b + p
    ur = []
    for v in z:
        ur.append('https://www.biquge9.com' + v)
    with ThreadPoolExecutor(50)as f:
        for url in ur:
            f.submit(download,url=url,file=file)
