Json data processing server

A small back-end program today, to deal with json data, express frame I can not directly address the need for json extraction, the Internet to find a pile and found four kinds of parsing json format, look at this record

• www-form-urlencoded
• form-data
• application/json
• text/xml

There are four format handling, first add the Python modules:

1 var express = require('express');
2 var app = express();
3 var bodyParser = require('body-parser');

The process then different formats:

www-form-urlencoded：

app.use(bodyParser.urlencoded({
    extended:true
}));
app.post('/urlencoded', function(req, res){
    console.log(req.body);
    res.send(" post successfully!");
});
app.listen(3000);

from-data:

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

application/json:

var express = require('express');
was app = Out ();
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.post('/urlencoded', function(req, res){
    console.log(req.body);
    res.send(" post successfully!");
});
app.listen(3000);

text/xml:

var express = require('express');
var bodyParser = require('body-parser');
var xml2json=require('xml2json');
was app = Out ();
app.use(bodyParser.urlencoded({
  extended: true
}));
app.post('/xml', function (req, res) {
  req.rawBody = '' ; // add to receive variables
  was 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);

Note: I believe in micro small program is application / json post request of the successful interaction.
