var http = require('http');
var fs = require('fs');
var url = require('url');
var querystring = require('querystring')
    //console.log(http);
http.createServer(function(request, response) {
    request.setEncoding('utf-8');
    //获取请求路径 比如index.html
    var pathname = url.parse(request.url).pathname;
    //获取请求参数 例如?callback=JSON_CALLBACK&name=yao
    var paramStr = url.parse(request.url).query;
    console.log(pathname);
    //将参数转化为json对象
    var param = querystring.parse(paramStr);
    console.log(param.callback);
    //发送 HTTP 头部 
    //HTTP 状态值: 200 : OK
    //内容类型: text/plain
    response.writeHead(200, {
        'Content-Type': 'text/jsonp'
    });
    var datas = {
        name: "wsscat",
        age: "99",
        sex: "cat",
        skill: ["html", "css", "js", "php"]
    };

    //发送响应数据
    //"angular.callbacks._0"才能正确执行&&JSON_CALLBACK不能正确执行
    //转化为jsonp的格式传递
    response.end(param.callback + "(" + JSON.stringify(datas)+")");
}).listen(8888);

//终端打印如下信息
console.log('Server running at http://127.0.0.1:8888/');
