用python搭建web服务器，与ajax交互，接收处理Get和Post请求；简单实用，没有用框架，适用于简单需求，更多功能可进行扩展。
python有自带模块BaseHTTPServer、CGIHTTPServer、SimpleHTTPServer，详细功能可参考API
前台html：
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <title>test</title> 5 </head> 6 <body> 7 <h1>test</h1> 8 <p>this is a test page!</p> 9 <button onclick="get()">click</button> 10 <div id="result"></div> 11 <script src="libsjquery-3.2.1.min.js"></script> 12 <script> 13 function get(){ 14 //alert("test"); 15 $.ajax({ 16 url:"BaseInfo", 17 data:{id:123,name:"xiaoming"}, 18 success:function(e){ 19 $("#result").html(e); 20 }}) 21 } 22 </script> 23 </body> 24 </html>
python代码：
