curl succeeds with oath2 but fails with node.js request - node.js

Question

The following curl request works properly, returning the authentication token as it should
curl POST -s -d "grant_type=password&username=someusername&password=somepassword&client_id=someid&client_secret=somesecret&response_type=token" "someurl"
when the equivalent request in node.js fails
let url = someurl
var dataString = 'grant_type=password&username=somename&password=somepassword&client_id=someid&client_secret=somesecret&response_type=token';
var options = {
url: url,
method: 'POST',
body: dataString,
allow_redirects : true
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
console.log(error)
console.log(body)
}
request(options, callback);
The error is
{"error":"unauthorized","error_description":"An Authentication object was not found in the SecurityContext"}
Which may only be specific to this code. At any rate, what differences (in default parameters presumably or configuration) could explain this difference. Note, the programs fails both with and without allow_redirects option, but redirection should be allowed.
This is node v7.10.0 running on macosx and request 2.81.0

Answer 1

My first assumption would be that you're missing the headers required for your request
let url = someurl
var dataString = 'grant_type=password&username=somename&password=somepassword&client_id=someid&client_secret=somesecret&response_type=token';
var options = {
url: url,
method: 'POST',
body: dataString,
headers: { 'content-type': 'application/x-www-form-urlencoded' },
allow_redirects: true
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
console.log(error)
console.log(body)
}
request(options, callback);
If this isn't correct, let me know and i'll resolve the answer
