Node.js，Ajax发送和接收Json

在服务器端尝试此操作：

var port = 8000;var http = require("http");var server = http.createServer();server.on('request', request);server.listen(port);function request(request, response) {    var store = '';    request.on('data', function(data)     {        store += data;    });    request.on('end', function()     {  console.log(store);        response.setHeader("Content-Type", "text/json");        response.setHeader("Access-Control-Allow-Origin", "*");        response.end(store)    }); }

在客户端：

$.ajax({  type: "POST",  url: "http://localhost:8000",  crossDomain:true,   dataType: "json",  data:JSON.stringify({name: "Dennis", address: {city: "Dub", country: "IE"}}) }).done(function ( data ) {      alert("ajax callback response:"+JSON.stringify(data));   })

希望这对你有用
