基于node.js依赖express解析post请求四种数据格式

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({
 extended:true
}));
app.post('/urlencoded', function(req, res){
 console.log(req.body);
 res.send(" post suessfully!");
});
app.listen(3000);

var multipart = require('connect-multiparty');
var multipartMiddleware = multipart();
app.post('/formdata',multipartMiddleware, function (req, res) {
console.log(req.body);
res.send("post suessfully!");
});

app.use(bodyParser.json());

var express = require('express');
var bodyParser = require('body-parser');
var xml2json=require('xml2json');
var app = express();
app.use(bodyParser.urlencoded({
extended: true
}));
app.post('/xml', function (req, res) {
req.rawBody = '';//添加接收变量
var json={};
req.setEncoding('utf8');
req.on('data', function(chunk) { 
req.rawBody += chunk;
});
req.on('end', function() {
json=xml2json.toJson(req.rawBody);
res.send(JSON.stringify(json));
}); 
});
app.listen(3000);
