有时候在GReader阅读的时候想分享点文章到人人，使用GReader的Send-to功能感觉颇麻烦(要不就是俺弄的Send-to设置不好)，要登录到分享页，再点击次确定才完成分享。
想到之前 @shellex 猫写的 用GAE同步twitter到人人网状态 的python脚本，是否可以借用来做些修改来实现GReader分享到人人的目的？
于是乎年前几天无聊，兼python都快忘完了，就动手丰衣足食写脚本。首先是RSS解析的库，Google了下，找到了 feedparser 这个RSS解析库，官网也列出了一部分使用方法，可以满足基本需要了。
解析好RSS后剩下的功能和 @shellex 的脚本就差不多了。登录+发送状态。
其实这脚本写了两个版本，先写了个本地的，后面又改成GAE的版本＝，＝折腾。（一开始就弄个GAE的不就好了嘛-___-#）主要之前也写过一个类似的“登录＋发送状态”的机器人，只要把RSS解析弄好就可以使用了，想着偷懒呢。
代码有一块注释没删掉，是写本地版本的时候用的登录代码。貌似在GAE上用不了。不知道是不是urllib2的缘故。Cookie和cookielib还要区分下-_____-!!
脚本同时参考了梦.:如此短暂的用GAE同步twitter到人人网状态
脚本后面有过修改，就是先检查最新的分享条目，再登录人人更新，要不每次都登录多少感觉不爽。
