Get ajax sending data on nodejs server

Question

I had simple ajax request(request from external server)

             $.ajax({
                type: "POST",
                url: "http://localhost:8001/startApps",
                data: 'sss',
                success: function (data) {
                    console.log('AllOk');
                },
                error: function(XMLHttpRequest, textStatus, errorThrown) {
                    console.log('err: '+XMLHttpRequest.status);
                }
            });

how i could get this data : 'sss' on node js server

app.post('/startApps', function (req,res,next) {
    console.log(req.body);//I trying req.data, req.params req.query etc ..
    res.send('Ok');
})

@YanetPedraza req.data, req.body return undefined. req.query and req.params return {} — ItsMyLife

Did you check if you put your body-parser code above all the routes — YanetP1988

@YanetPedraza bodyParser required var bodyParser = require('body-parser'); — ItsMyLife

Check body-parser in express:

var express = require('express'),
    app     = express(),
    port    = parseInt(process.env.PORT, 10) || 8080;

app.configure(function(){
  app.use(express.bodyParser());
  app.use(app.router);
});

app.listen(port);

By default $.ajax defaults to application/x-www-form-urlencoded as the content type to send to server. In your case i hope you are sending plain data. Hence you should use contentType as text/plain to send data and fetch it on server as plain text.

 $.ajax({
            type: "POST",
            url: "https://localhost:8001/startApps",
            data: 'sss',
            contentType:'text/plain',
            success: function (data) {
                console.log('AllOk');
            },
            error: function(XMLHttpRequest, textStatus, errorThrown) {
                console.log('err: '+XMLHttpRequest.status);
            }
        });

Try this to see if it works

$.ajax({
            type: "POST",
            url: "http://localhost:8001/startApps",
            data: 'sss',
            dataType : "text",
            success: function (data) {
                console.log(data);
            },
            error: function(XMLHttpRequest, textStatus, errorThrown) {
                console.log('err: '+XMLHttpRequest.status);
            }
});

app.post('/startApps', function (req,res,next) {
    res.send('Ok');
})

its work. I cat get response data from server. But how i could get request data on server?

Stackgeek Over a year ago

Are you using bodyParser?

ItsMyLife Over a year ago

bodyPArser required var bodyParser = require('body-parser');

ImClarky Over a year ago

@ItsMyLife - Your data value sss needs a key so like: data: {key: 'sss'}, then you can access it using req.body.key

Stackgeek Over a year ago

Try to put these lines above all your routes in your app.js file to see if it works app.use(bodyParser.urlencoded()); app.use(bodyParser());
