• 怒赞的一个爬虫框架，基于 tornado，妈的，这个得好好学习
• 去重的逻辑用下这个库来搞
• 部署、控制相关的用这个

分布式

比如如何防止被 ban 掉

Here are some tips to keep in mind when dealing with these kinds of sites:
- rotate your user agent from a pool of well-known ones from browsers (google around to get a list of them)
- disable cookies (see COOKIES_ENABLED) as some sites may use cookies to spot bot behaviour
- use download delays (2 or higher). See DOWNLOAD_DELAY setting.- if possible, use Google cache to fetch pages, instead of hitting the sites directly
- use a pool of rotating IPs. For example, the free Tor project or paid services like ProxyMesh
- use a highly distributed downloader that circumvents bans internally, so you can just focus on parsing clean pages. One example of such downloaders is Crawlera
