失败的爬虫 成功的尝试
在爬取完漫画网站之后，我在想，我还能用自己浅薄的知识做点什么，但实在是因为自己 python的基本功不够扎实，以及自己的需求过于模糊，所以最后还是选择了爬取笔趣阁的小说。练习python，熟悉bs4 和 requsets 的使用。
因为想要使用多进程，所以是用的与之前不一样的写法，以及困于PyChram的输入网址之后直接回车就会打开浏览器，所以默认多加一个字符长度，默认是空格
首先是爬取文章标题
#
from bs4 import BeautifulSoup
import requests
def get_titles(urlx):
wb_data = requests.get(urlx)
wb_data.encoding = 'UTF-8'
soup = BeautifulSoup(wb_data.text, 'lxml')
return soup.select('h1')[0].get_text()其次是 爬取文章目录
#
from bs4 import BeautifulSoup
import requests
import pymongo
head = 'https://www.biquge.com.cn'
client = pymongo.MongoClient('localhost', 27017)
BQG = client['BQG']
chapters = BQG['chapters']
def get_chapters(urlx):
wb_data = requests.get(urlx)
wb_data.encoding = 'UTF-8'
soup = BeautifulSoup(wb_data.text, 'lxml')
local_chapters = soup.select('dd > a')
for index, each in enumerate(local_chapters):
local_chapter = {
'index': index,
'url': head+each.get('href')
}
chapters.insert_one(local_chapter)然后是 爬取 文章内容
#
from bs4 import BeautifulSoup
import requests
import pymongo
client = pymongo.MongoClient('localhost', 27017)
BQG = client['BQG']
books = BQG['books']
chapters = BQG['chapters']
articles = BQG['articles']
def get_articles(urlx):
wb_data = requests.get(urlx)
wb_data.encoding = 'UTF-8'
soup = BeautifulSoup(wb_data.text, 'lxml')
wb_data.close()
title = {'T|C': 1, 'm': soup.select('div.bookname > h1')[0].get_text()}
articles.insert_one(title)
content = soup.select('#content').__str__().replace('[<div id="content">', '').replace('</div>]', '').replace('\xa0', '').split('<br/><br/>')
for each in content:
paragraph = {
'T|C': 0,
'm': each
}
articles.insert_one(paragraph)主程序：
import pymongo
import os
from multiprocessing import Pool
from zerox.bqg_get_chapters import get_chapters
from zerox.bqg_get_articles import get_articles
from zerox.bqg_get_titles import get_titles
client = pymongo.MongoClient('localhost', 27017)
BQG = client['BQG']
books = BQG['books']
chapters = BQG['chapters']
articles = BQG['articles']
rootpath = '/home/x/BORBER/File/Tmp/novel/'
filend = '.txt'
def write_in(item):
if item['T|C'] == 1:
file.write(item['m'])
file.write('\n\n\n\n')
else:
print(' ')
file.write(item['m'])
file.write('\n\n')
if __name__ == '__main__':
BQG.drop_collection('books')
BQG.drop_collection('chapters')
BQG.drop_collection('articles')
pool = Pool()
print('Enter the specific link to the novel:')
url = input()[:-1]
title = get_titles(url)
a = rootpath + title + filend
file = open(rootpath + title + filend, 'w')
get_chapters(url)
for item in chapters.find():
get_articles(item['url'])
for item in articles.find():
write_in(item)以下提供 监测程序：
import time
import pymongo
import os
client = pymongo.MongoClient('localhost', 27017)
BQG = client['BQG']
books = BQG['books']
chapters = BQG['chapters']
articles = BQG['articles']
while True:
os.system('clear')
print(chapters.find().count()+articles.find().count())
time.sleep(2)文件结构：
-zero
-zerox #python package
-bqg_get_chapters.py
-bqg_get_articles.py
-bqg_get_titles.py
-count.py
-main.py
-__init__.py但是 为什么文章叫 失败的爬虫呢？ 因为我只成功了两次，后面的话就会报错了，应该是 笔趣阁的反扒手段，所以还是同样，如果以后我的技术进步了，我会着手改进这个爬虫的 ，有想尝试的朋友可以先试着加个 headers 到 get方法。
此爬虫需要使用 mongoDB
真的去下苦工 打基础了 (๑•̀ㅂ•́)و✧
