Could someone show me the simplest way to send a post request from node.js Express, including how to pass and retrieve some data? I am expecting something similar to cURL in PHP.

var request = require('request');
function updateClient(postData){
var clientServerOptions = {
uri: '
body: JSON.stringify(postData),
method: 'POST',
headers: {
'Content-Type': 'application/json'
}
}
request(clientServerOptions, function (error, response) {
console.log(error,response.body);
return;
});
}
For this to work, your server must be something like:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json())
var port = 9000;
app.post('/sample/put/data', function(req, res) {
console.log('receiving data ...');
console.log('body is ',req.body);
res.send(req.body);
});
// start the server
app.listen(port);
console.log('Server started! At + port);
As described here for a post request :
var http = require('http');
var options = {
host: '
path: '/',
port: '80',
method: 'POST'
};
callback = function(response) {
var str = ''
response.on('data', function (chunk) {
str += chunk;
});
response.on('end', function () {
console.log(str);
});
}
var req = http.request(options, callback);
//This is the data we are posting, it needs to be a string or a buffer
req.write("data");
req.end();
you can try like this:
var request = require('request');
request.post({ headers: {'content-type' : 'application/json'}
, url: <your URL>, body: <req_body in json> }
, function(error, response, body){
console.log(body);
});
I use superagent, which is simliar to jQuery.
Here is the docs
And the demo like:
var sa = require('superagent');
sa.post('url')
.send({key: value})
.end(function(err, res) {
//TODO
});
in your server side the code looks like:
var request = require('request');
app.post('/add', function(req, res){
console.log(req.body);
request.post(
{
url:'
json: {
unit_name:req.body.unit_name,
unit_price:req.body.unit_price
},
headers: {
'Content-Type': 'application/json'
}
},
function(error, response, body){
// console.log(error);
// console.log(response);
console.log(body);
res.send(body);
});
// res.send("body");
});
in receiving end server code looks like:
app.post('/add', function(req, res){
console.log('received request')
console.log(req.body);
let adunit = new AdUnit(req.body);
adunit.save()
.then(game => {
res.status(200).json({'adUnit':'AdUnit is added successfully'})
})
.catch(err => {
res.status(400).send('unable to save to database');
})
});
Schema is just two properties unit_name and unit_price.
