python,tkinter（Python如何使用tkinter编写GUI程序）

@(Python3中tkinter写的HTTP测试工具代码支持正则表达式和XPATH)

程序非常简单            ，暂时只支持GET方法
 
  
 
  
 
  
 
  
 
  
 
 ，使用内置库tkinter编写GUI窗口











，在Mac下运行效果图如下  
  
  
  
  
  ，windows运行需要更改控件宽度高度等控制参数才能很好的显示 
  
  
  
  
  
。

效果图（使用XPATH匹配房天下网站）

代码如下 
  
  
  
  
  
 ，需要安装requests和lxml第三方库
