Python代碼如下:
1 # -*- coding: utf-8 -*- 2 import urllib.request 3 from bs4 import BeautifulSoup 4 5 #get book‘s chapter 6 def get_chapter(url): 7 html = urllib.request.urlopen(url) 8 content = html.read().decode(‘utf8‘) 9 html.close() 10 soup = BeautifulSoup(content, "lxml") 11 title = soup.find(‘h1‘).text #chapter title 12 text = soup.find(‘div‘, id=‘htmlContent‘) #chapter content 13 #processing the content to get nice style 14 content = text.get_text(‘\n‘,‘br/‘).replace(‘\n‘, ‘\n‘) 15 content = content.replace(‘ ‘, ‘\n ‘) 16 return title, ‘ ‘+content 17 18 def main(): 19 books = [‘射雕英雄傳‘,‘天龍八部‘,‘鹿鼎記‘,‘神雕俠侶‘,‘笑傲江湖‘,‘碧血劍‘,‘倚天屠龍記‘,20 ‘飛狐外傳‘,‘書劍恩仇錄‘,‘連城訣‘,‘俠客行‘,‘越女劍‘,‘鴛鴦刀‘,‘白馬嘯西風‘,21 ‘雪山飛狐‘] 22 order = [1,2,3,4,5,6,7,8,10,11,12,14,15,13,9] #order of books to scrapy 23 #list to store each book‘s scrapying range 24 page_range = [1,43,94,145,185,225,248,289,309,329,341,362,363,364,375,385] 25 26 for i,book in enumerate(books): 27 for num in range(page_range[i],page_range[i+1]): 28 url = "http://jinyong.zuopinj.com/%s/%s.html"%(order[i],num) 29 try: 30 title, chapter = get_chapter(url) 31 with open(‘E://%s.txt‘%book, ‘a‘, encoding=‘gb18030‘) as f: 32 print(book+‘:‘+title+‘-->寫入成功!‘) 33 f.write(title+‘\n\n\n‘) 34 f.write(chapter+‘\n\n\n‘) 35 except Exception as e: 36 print(e) 37 print(‘全部寫入完畢!‘) 38 39 main()
