Can send post request with curl but cannot from a node server - node.js

Question

I can make a post request to a REST api endpoint of a web service with curl successfully but couldnt do so with request module in node.js. Instead, I always get error CONNECTION ETIMEDOUT.What is the problem?
curl command:
curl -i --header "Content-Type: application/json" -XPOST 'http://<endpoint_url>/urls' -d '{
"callback": "http://www.example.com/callback",
"total": 3,
"urls": [ {
"url": "http://www.domain.com/index1.html"
}, {
"url": "http://www.domain.com/index2.html"
}, {
"url": "http://www.domain.com/index3.html"
}
]
}'
code:
function sendRequestToEndPoint() {
const sample = {
"callback": "http://www.example.com/callback",
"total": 3,
"urls": [ {
"url": "http://www.domain.com/index1.html"
}, {
"url": "http://www.domain.com/index2.html"
}, {
"url": "http://www.domain.com/index3.html"
}
]
}
const options = {
method: 'post',
//headers: {
// 'Content-Type': 'application/json',
// 'Accept': 'application/json',
//},
url: 'http://<endpoint_url>/urls',
json: sample
//body: JSON.stringify(sample) // also tried this with headers on
};
console.log(sample);
request(options, (error, response, body) => {
console.log(response)
});
}
Update: Turned out that it was because the api url I used is not correct.

Answer 1

use querystring to stringify your json data,
var querystring = require('querystring');
...
sample = querystring.stringify(sample);
look at this answer How to make an HTTP POST request in node.js

Answer 2

this code works,
you need to Stringify your json object using JSON.stringify , and use the methode write of the object request to send the sample json object
, http = require('http')
, bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: false
}));
var sample = JSON.stringify({
"callback": "http://www.example.com/callback"
, "total": 3
, "urls": [{
"url": "http://www.domain.com/index1.html"
}, {
"url": "http://www.domain.com/index2.html"
}, {
"url": "http://www.domain.com/index3.html"
}
]
});
var options = {
hostname: 'localhost'
, port: 80
, path: '/test/a'
, method: 'POST'
, headers: {
'Content-Type': 'application/json'
, 'Content-Length': sample.length
}
};
app.get('/', function (req, res) {
var r = http.request(options, (response) => {
console.log(`STATUS: ${response.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(response.headers)}`);
response.setEncoding('utf8');
response.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
response.on('end', () => {
console.log('No more data in response.');
});
});
r.on('error', (e) => {
console.log(`problem with request: ${e.message}`);
});
r.write(sample);
r.end();
res.send('ok');
});
