I'm trying to make a healthcheck for my service in New Relic. So I just want to call one of my APIs every x minutes and see if it returns 200. In New Relic I created a new synthetic monitor and now I'm trying to write a script for that monitor.

The script is supposed to make a post request to our service and receive a token in the response with status 200. In Postman this post request works and returns the token + Status 200 (I replaced the sensitive strings with <...>):

curl --location --request POST <TOKEN_URL> \

--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'client_id=<CLIENT_ID_DEV>' \
--data-urlencode 'client_secret=<CLIENT_SECRET_DEV>'

But when I try to recreate that with the script, it always returns Status 400 Bad Request.

This is my script:

var assert = require('assert');

//Defining my authentication credentials.
var IDK_TOKEN_URL = $secure.TOKEN_URL;
var CLIENT_ID = $secure.CLIENT_ID_DEV;
var CLIENT_SECRET = $secure.CLIENT_SECRET_DEV;

var options = {
url: IDK_TOKEN_URL,
body: JSON.stringify({
  grant_type: 'client_credentials',
  client_id: CLIENT_ID,
  client_secret: CLIENT_SECRET,
}),
headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
    }
};

//Define expected results using callback function.
function callback(error, response, body) {
console.log(response.statusCode + " status code")
assert.ok(response.statusCode == 200, 'Expected 200 OK response');
var info = JSON.parse(body);
assert.ok(info.success == true, 'Expected True results in Response Body, result was ' + info.success);
console.log("End reached");
}

//Make POST request, passing in options and callback.
$http.post(options, callback);

This is what I see in the console:

new relic console

It seems to automatically append a port 443 to my url, so instead of <my url>.io/oidc/v1/token, the request seems to get fired to <my url>.io:443/oidc/v1/token?

And when I click on "View resource" in the image above, I see:

![grafik|636x148](upload://k12h5iGDkE1m2JdTSvQ8L2Qcy2j.png)

But I'm using a post method, why is it saying anything about get method is not allowed?

This is the HAR log that I can download in the new relic console:

我不得不像在这个例子中那样用 'form' 替换 'body' 。

在收到令牌后，我现在还添加了对 API 的调用。最终的脚本是：

var assert = require('assert');
//Define your authentication credentials.
var TOKEN_URL = $secure.TOKEN_URL;
var MY_SERVICE_BASE_URL = $secure.MY_SERVICE_BASE_URL_DEV;
var CLIENT_ID = $secure.CLIENT_ID_DEV;
var CLIENT_SECRET = $secure.CLIENT_SECRET_DEV;

function new_relic_callback(err, response, body) {
  assert.equal(response.statusCode, 200, 'Expected a 200 OK response');
};

function api_request_callback(err, response, body) {
  var parsed_body = JSON.parse(body); 
  
  var api_request = {
    url: CONSENT_BASE_URL + '/rest of URL...',
    headers: {
      'Authorization': 'Bearer ' + parsed_body["access_token"]
    }
  };

  $http.get(api_request, new_relic_callback);
};

var token_request = {
  url: TOKEN_URL,
  form: {
    client_id: CLIENT_ID,
    client_secret: CLIENT_SECRET,
    grant_type: "client_credentials"
  },
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
    }
};

$http.post(token_request, api_request_callback);
