make a post request with a body in nodejs - node.js

Question

I am using nodeJS to communicate with an API.
To do that, I am using a post request.
In my code, I use form data to pass the variables, but I get error 400. When I try to put body instead, I get an error saying that my variables are undefined.
This is the API: https://developer.hpe.com/api/simplivity/endpoint?&path=%2Fdatastores
My request:
async function postCreateDatastore(url, username, password, name, clusterID, policyID, size, token) {
console.log (name, clusterID, policyID, size)
var options = {
method: 'POST',
url: url + '/datastores',
headers: {
'Content-Type': 'application/vnd.simplivity.v1.1+json',
'Authorization': 'Bearer ' + token,
},
formdata:
{
name: name,
omnistack_cluster_id: clusterID,
policy_id: policyID,
size: size,
}
};
return new Promise(function (resolve, reject) {
request(options, function (error, response, body) {
if (response.statusCode === 415) {
console.log(body);
resolve(body);
} else {
console.log("passed");
console.log(JSON.parse(body));
resolve(response.statusCode);
}
});
});
}

I advice to use node-fetch to post your data. This package let you use the default fetch function from ES6.
Here is your answer:
//require the node-fetch function
const fetch = require('node-fetch');
async function postCreateDatastore(url, username, password, name, clusterID, policyID, size, token) {
console.log(name, clusterID, policyID, size);
try {
const response = await fetch(`${url}/datastores`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer ' + token,
},
body: JSON.stringify({
name,
omnistack_cluster_id: clusterID,
policy_id: policyID,
size
})
});
const json = await response.json();
console.log(json);
return json;
}
catch(e) {
throw e;
}
}
