REST API Call with NodeJS

var http = require('http');

                   // catch data to be sent

data = {"foo":"bar"}

// parsing data

jdata = JSON.parse(data);

// create the JSON object

jsonObject = JSON.stringify(jdata);

// prepare the header

var postheaders = {

    'Content-Type' : 'application/json',

    'Content-Length' : Buffer.byteLength(jsonObject, 'utf8')

};

// the post options

var optionspost = {

    host : 'localhost',

    port : 3001,

    path : '/error_requests',

    method : 'POST',

    headers : postheaders

};

console.info('Options prepared:');

console.info(optionspost);

console.info('Do the POST call');

// do the POST call

var reqPost = http.request(optionspost, function(res) {

    console.log("statusCode: ", res.statusCode);

    console.log("headers: ", res.headers);

    res.on('data', function(d) {

        console.info('POST result:\n');

//         process.stdout.write(d);

        console.info(d);

        console.info('\n\nPOST completed');

    });

});

// write the json data

reqPost.write(jsonObject);

reqPost.end();

// handle error

reqPost.on('error', function(e) {

    console.error(e);

});
