无聊空间

昨晚搞定的，最近好熟识python的qtwebkit的操作，以下是qtwebkit登录新浪微博的python源码，其实发微博的都搞定了，但未能完善，这个理清思路再细致点的搞.

这样操作发微博，好过用新浪的微博api sdk来搞，不过就是复杂点就是了.

以下是qtwebkit登录新浪微博代码

sys.exit(app.exec_())

timetest函数是打开网址延时4秒, 等所有东西加载完毕。

换成自己的登录帐号和密码，
然后注释这行： #elem[0].evaluateJavaScript(self.js_click) ， 才可以提交的

关于python的qtwebkit国内资料还是少，好在我的英语基础还是不错，google翻译辅助下，终于在国外找到点能用的资料.

继续学习qtwebkit去…
