Python备份百度博客

开始学Python,就看看urllib模块，然后参考网上的一些资料，自己动手写 一个，新手完全不顾效率和程序的美观，只想试下。最难的部分在于正则，看了一些资料，还是不会，只好凑合使用，莫见笑~

                htmlUrl = '' + user + blogUrl[0]
                print htmlUrl
                downloadpage(blogUrl = blogUrl[0])#递归你所有的文章
            else:
                break
            

            sock.close()
            return

            print 'download blog fail: %s' % (blogUrl)
      
downloadpage()


用之前，需要在文件所在目录新建一个目录，例如我的博客就是 codedeveloper,使用这段程序，需要更改两个参数：

downloadpage(user = "yours",blogUrl = '/blog/item/yournewestblogurl.html')
其中user那里指的是你的用户名，yournewestblogurl说的是你最新那篇博文的地址~
等我进一步学习，我在慢慢改善~ 比如使用线程，wget下载等，还有就是处理图片问题。
