if __name__ == "__main__":
    try:

        eval(type.upper())(url)
    except:
        print("获取出错，可能URL错误\n使用格式name.exe url type\n请使用--help查看帮助")

但是我认为这个源码并不是很好，主要有一下几个方面：

1、doc文档保存的是txt文件，所有的格式都没有了，如果doc文件中有图片，图片也没有了；

2、PPT、PDF文件保存的是图片，这个无法编辑是一个很头疼的问题。

综上所述，这个源码并不是很好，最近找打了一个比较好的源码，正在调试。

调试好了，做成一个百度文库在线服务，地址会留下来，欢迎大家关注。
