初用Python:Tkinter做的Http小工具

博主平时做移动app开发，与服务端交互时常需要单独看看请求结果，嫌打印Log烦，开网页low，于是有了个小工具。

界面用Tkinter做的，发请求用的urllib2，可动态添加参数，暂未处理request header，运行图：

源码：http://download.csdn.net/detail/ober2012/9450126    (python代码可能有点java风格，勿喷。。)

代码不长，都直接贴出来了：

 （1）__init__.py 程序入口，主要是主界面布局逻辑和2个按钮响应函数

（2）UiItem.py 包装了3个小控件，直接看图：

MethodCheckBox:

HostBox:

ParamItem:
