server端代碼

var http = require("http"); var url = require('url'); //訪問地址：http://127.0.0.1:4000/?callback=ccc&name=allen&age=18&_=1491380773607 http.createServer(function(req, res) {var arg = url.parse(req.url,true).query; //{callback:'ccc',name:'allen',age:'18',_'1491380773607'}var callbackName = arg.callback;var responseData = {'code':'A00000','data':'akalaka'}; var responseString = JSON.stringify(responseData);//ajax訪問時，沒它會報錯res.setHeader("Access-Control-Allow-Origin", "*");if (callbackName) { var jsonpResponse = callbackName+'('+responseString+')';//jsonpResponse = 'alert(123)'; //直接返回，會出彈窗 res.end(jsonpResponse); } else { res.end(responseString); } console.log(req.url); }).listen(4000);console.log("HTTP server is listening at port 4000.");
