1.JavaScript 加密什么的最讨厌了 :-(
1).eval 一个不依赖外部变量的函数立即调用很天真,看我 nodejs 来干掉你!
2).HTTP 请求的验证首先尝试 Referer,「小甜饼」没有想像中的那么重要。
3).curl 和各命令行工具处理起文本很顺手呢
4).但是 Python 也没多几行呢
2.Requests 效率比 lxml 自己那个好太多
3.progressbar 太先进了,我还是自个儿写吧……
4.argparse 写 Python 命令行程序必备啊~
5.string.Template也很好用哦
6.以下是主代码啦,除了标准库以及 lxml 和 requests,没有的模块都在无所不能的 winterpy 仓库里。其实主代码也在的。
