每个页面默认都会再发一个de style="line-height: 21px; padding: 4px 6px; font-family: Monaco, Menlo, Consolas, 'Courier New', monospace; font-size: 12px; color: rgb(0, 0, 0); border-radius: 1px; white-space: nowrap; border: none; margin: 0px 1px; background: 0px 0px
rgb(252, 250, 250);" >/favicon.icode>

de style="line-height: 21px; padding: 0px; font-family: Monaco, Menlo, Consolas, 'Courier New', monospace; font-size: 12px; color: inherit; border-radius: 3px; border: 0px; background-color: transparent;"  >var http=require('http');
var i=0;
var req=function(req,res){
i=i+1;
console.log(i,req.url);
res.writeHead(200,{'Content-Type':'text/plain'});
res.end('Hello World\n');
};

http.createServer(req).listen(8888,"127.0.0.1");
console.log('Server running...');de>

##控制台输出：

de style="line-height: 21px; padding: 0px; font-family: Monaco, Menlo, Consolas, 'Courier New', monospace; font-size: 12px; color: inherit; border-radius: 3px; border: 0px; background-color: transparent;"  >Server running...
