最近在做一些,基于浏览器的应用整合项目。使用到了DJNative (一种JAVA浏览器实现http://sourceforge.net/projects/djproject/files/DJ%20Native%20Swing/0.9.9%20preview/DJNativeSwing-SWT-0-9-9-20110224.zip/download),对于一些进行接口开发的业务整合系统,提供了一种不错的思路。周末兴趣所致,写了一个新浪微博自动登录的例子。
实现一下功能:1,如果已经登录过的用户,读取配置文件中的用户名密码,调用当前页面自动完成登录。
2,如果未登录用户提示用户输入用户名密码,在用户登录成功后自动截取用户名密码保存到配置文件。
3,当用户名密码出错时清楚已保存的用户名密码,提示用户重新登录。
第一次运行时 提示没有从配置文件中读取到用户名密码
输入用户名密码:
输入用户名密码成功:成功登录
这时已将用户名密码保存到userProperties.properties中
再次运行时将自动完成新浪微博的登录!
完整的代码如下:
