VOA Special English MP3 Downloader

885 views 三月 10, 10 by Timothy

最近上下班开车挺无聊，听腻了各式音乐，打算利用上下班的时间学学英语，锻炼下生锈的耳朵，听听English MP3。以前一直比较喜欢VOA Special English的慢速版，虽然还是有一定的难度，但听起来多少能找到点感觉。今天突然心血来潮，google了下VOA的老家，很不幸，网页无法打开，第一直觉就是VOA被伟大的wall给挡住了。搜索了一下，果然如此……不过咱有SSH，怕啥？通过SSH果然可以正常访问，这也印证了前面的猜想。不过VOA的mp3貌似每天都出，一个一个点链接下载，实在是个体力活，人本来就有惰性，俺也不例外！于是，有了下面的想法……

咱IT民工，比较拿手的就是让电脑帮俺们去完成一些重复劳动，减轻体力负担，如果能让电脑自动帮俺下载mp3该多好！加之最近又在看python的东东，python很强大，几行代码就能完成复杂的工作。于是开始手痒，何不用python搞个下载器试试呢？ 对了，有wall，怎么办？不怕！咱有VPS，哈哈哈！

开工！在VOA的页面，上找到RSS页面地址(RSS页面包含有最新发布的文章以及mp3下载链接)，然后对RSS进行分析，写python脚本，调试，运行，效果还不错！最近发布文章的mp3被啪啪啪的拖到了VPS上。脚本十分简单：

VPS和VOA都在米国，下载速度很快啊……几秒钟的功夫……

最后，再想办法把mp3统统拖回来本地即可。此脚本适合拥有VPS的、有兴趣的同学使用，后续会慢慢改进脚本。
