var express = require('express');
//Post方式请求参数放在请求体里面，需引用body-parser解析body
var bodyParser = require("body-parser");
var app = express();

// 引用
app.use(bodyParser.urlencoded({ extended: false }));

//设置跨域访问
app.all('*', function(req, res, next) {
 res.header("Access-Control-Allow-Origin", "*");
 res.header("Access-Control-Allow-Headers", "X-Requested-With");
 res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS");
 res.header("X-Powered-By",' 3.2.1');
 res.header("Content-Type", "application/json;charset=utf-8");
 next();
});

//json数据
var data = { "name": "Test", "age": "19" };

app.get('/', function(req, res) {
 console.log('get..........');
 console.log(req.query);
 if (req.query && req.query.callback) {
  var str = req.query.callback + "(" + JSON.stringify(data) + ")"; //jsonp 
  console.log('jsonp: '+str);
  res.end(str);
 }else{
  console.log('json: '+JSON.stringify(data));
  res.end(JSON.stringify(data));
 }
});

app.post('/', function(req, res) {
 console.log('post............');
 console.log(req.body);
 console.log('json: '+JSON.stringify(data));
 res.end(JSON.stringify(data));
});

app.listen(8085, function () {
 console.log('Listening on port 8085...');
});
