Is there a way to create new request object in a javascript policy?

Hi,

It is clear that the AssignMessage policy has the ability to create brand new request object, but is it possible to create one in the javascript code?

yes, you can create a new request object, which will be used to call an api inside the same javascript.

var myRequest = new Request();
myRequest.url = "http://www.example.com";
var exchangeObj = httpClient.send(myRequest);

Here's a more complete illustration, that uses the recommended callback mechanism.

  function onComplete(response, error) {
    if (response) {
      context.setVariable('example.status', response.status);
    }
    else {
      context.setVariable('example.error', 'Whoops: ' + error);
    }
  }


  var url = 'https://example.com/path1/' + id ;
  var headers = { 'ID-Index' : ix };
  var req = new Request(url, 'GET', headers);
  httpClient.send(req, onComplete);

or for a post, something like this:

var payload = JSON.stringify({
   foo : 'bar',
   whatever : 1234 
});
var headers = {
      'Content-Type' : 'application/json',
      'Authorization' : 'Bearer xyz'
    };
var url = 'https://example.com/path2';
var req = new Request(url, 'POST', headers, payload);


httpClient.send(req, onComplete);

Thank you very much for the detailed answers! And this request object couldn't replace the predefined in the context request variable, is this correct?

I.e I cannot do context.setVariable('request', new Request())

Nice day,

I don't know, I've never tried that. What are we solving for?

You can set the values on the existing request object. You can set the method, payload, headers, etc.
