nodejs express post 获取参数

###需要加入bodyParservar bodyParser = require('body-parser')app.use(bodyParser.urlencoded({ extended: fa

###需要加入bodyParser

var bodyParser = require('body-parser')app.use(bodyParser.urlencoded({ extended: false }));

###post方法app.post('/api', function (req, res) {//使用.param可以拿post、getvar page = req.param('page') || 1;var size = req.param('size') || 10;

###另，允许跨域的做法

app.all('*', function (req, res, next) {//      res.header("Access-Control-Allow-Origin", "*");这个对with credentials无效效        res.header("Access-Control-Allow-Origin", "http://XX.XX.com");        res.header("Access-Control-Allow-Credentials", true);            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", ' 4.2.1')        res.header("Content-Type", "application/json;charset=utf-8");        next();});
