node.js - Pass data from reactjs to nodejs

Question

I am trying to pass data from react js to nodejs. Can anyone help, Reactjs code -

$.ajax({
  url: 'http://localhost:8081/getdata',      
  type: 'POST',
  data: {ajaxid:4},
  success: function(data) {
    this.setState({EmpCollection: data.EmpCollection}); 
  }.bind(this),
  error: function(xhr, status, err) {
    console.error(this.props.Empnumber, status, err.toString());
  }.bind(this)

});

Nodejs code-

app.get('/getdata', function (req, res) {
var Client = require('node-rest-client').Client;
var client = new Client();
 var messageData =  "";
 console.log("req="+req);
  client.get("some URL", function (data, response) {            
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");      
  res.send(data);
});
})

How can i get ajaxid:4 in nodejs code?

You need to use the express plugin body-parser to access the POST data.

You can find more info how to do it here: How to retrieve POST query parameters?
