python编程获取续蜀山剑侠传：目录名称网址内容，保存到文件

Posted 2022-07-18 紫郢剑侠

昨天已经用Python编程完成了 从《续蜀山剑侠传》连载网站页面上获取目录信息，包括目录名称和网址，进而读取每个网址对应的网页中连载内容，详见：

今天我们要先统计出需要保存的网址数量，然后把每个网页国中的连载内容逐一保存到txt文件中，文件名就用目录名，然后调用记事本打开。为了避免枯燥，我们每保存1个txt就会更新并输出进度。

完整代码如下：

# -*- coding:UTF-8 -*-

#--------------------------

   try:
      page = urllib.request.urlopen(url, data=None, timeout=5)

     print(e.reason)
     return ''
   except urllib.error.URLError as e:
     print(e.reason)
     return ''
   else:    
      html = page.read().decode('utf-8')
      return html

#--------------------------

   showFile (fileSpec)
   
   os.system('notepad ' + fileSpec)
   #win32api.ShellExecute(0, 'open', fileSpec, '', '', 1)

#--------------------------

#--------------------------
def main():
   url = 'http://www.mengxi.net/book/263745/index.html'
   i = url.index('/', 7)
   host = url[0 : i]
   #print ('分析' + url)
   html = openUrl(url)
   if len(html) > 0:
      tag = '正文'
      list = getCon(html, tag)
     #printList(list, host)
     #showList(list, host)
      h = getListHref(list, host)
     print('共有' + str(len(h)) + '个页面')
     saveBook(h, host)

main()

代码运行结果如下：

 在Python中调用Windows的应用程序还是很方便的。
