how to call a function from another function - Node JS - node.js

Question

I am still new to Node Js. Please help me out.
I am calling a web service and based on its results I need to call another web service. The code is given below, however, I am not sure how to call the second web service (ex: foo()).
The 2nd method (That calls the 2nd web service) accepts 2 parameter:
Subject
Body
I need to call the web service 'https://somenew.com/v1/', and need to pass the following as headers as well :
`Content-Type : application/json`
Then As the body I need to pass the following properties :
"name": "My name is alex",
"gender": ["All"],
"Subject": "french",
"Body": "men",
"arrayOfLikes": {"sf": "tennis"}
// 1st Method
app.post('/createthehospital/',function(req,res){
var hos = req.body;
Hos.create(hos, function(err,hos){
if(err){
// Do nothing
} else {
foo('Subject', 'Body'); // CALLING NEW METHOD
}
}
})
});
// 2nd Method
function foo(subject,body) {
app.post('https://somenew.com/v1/',function(req,res){
});
}

You need to use request module
var request = require('request');
request.post({
url: 'https://somenew.com/v1/',
headers: {
'content-type': 'application/json',
},
json: {
"name": "My name is alex",
"gender": ["All"],
"Subject": "french",
"Body": "men",
"arrayOfLikes": {
"sf": "tennis"
}
}
}, function(error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // your response body
}
})
the mistake you have made use express instance app to make call to external url that is not possible use above module to do so.
