How to pass post data in http request method - json

Question

The following error prompts when my code executes.
It seems that bodyparameter could not be read.
missing required input JSON parameter requestType.
app.post('/compare', function (req, res, next) {
var options = {
host: 'hostname',
port: 80,
path: '/service',
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
'Authorization': "Basic " + new Buffer(username + ":" + pass).toString("base64")
},
body: JSON.stringify({
requestType: 'createService'
})
};
var httpreq = http.request(options, function (response) {
response.on('data', function (chunk) {
console.log("body: " + chunk);
});
response.on('end', function() {
res.send('ok');
})
});
httpreq.end();
});

I checked node's http modules latest documentation for request method.
It's options parameter does not accepts any body attribute
There is a example as well which shows that you need to pass body in write method
const postData = JSON.stringify({
requestType: 'createService'
});
const options = var options = {
host: 'hostname',
port: 80,
path: '/service',
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
'Authorization': "Basic " + new Buffer(username + ":" + pass).toString("base64")
}
};
const req = http.request(options, (res) => {
console.log(`STATUS: ${res.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
res.on('end', () => {
console.log('No more data in response.');
});
});
req.on('error', (e) => {
console.error(`problem with request: ${e.message}`);
});
// write data to request body
req.write(postData);
req.end();
