直接鼠标右键查看源码

其实原理很简单，在这个网址上点击进入每一章，然后下载里面的内容，例如第一章：第1章 1978年，在这个的href就是相对路径，所以前面加上该网址之后就是 http://www.aouchina.com/shu/31369/15059327.html  
进入该网址就是第一章的内容![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwNDUzOTcy_size_16_color_FFFFFF_t_70 2]  
再次右键查看源码：

找这个div下面的内容就是小说的内容，最后把所有小说内容循环写进txt中。  
最后附上py源码

        file.close()

期间遇到的问题：1 没有安装html5lib

控制台打印的进度和小节有点问题，就懒得改了。

最后附上上述代码运行后爬虫爬下的《大江大河》小说的txt下载路径  
复制这段内容后打开百度网盘App，操作更方便哦。 链接:https://pan.baidu.com/s/1gYbDpjo4PewdbvAOiQ7vNQ 提取码:edgq
