Disable Redirects

Grafana k6 OSS Support

Hi,

I have a scenario that is causing me some issues as one of the calls doesn’t accept the basic auth header as the domain changes.

I have a call that has two redirects.

  1. http://domain1.com/step1 - returns as a header the Location needed for step 2.
  2. http://domain1.com/step2 - returns as a header the Location needed for step 3.
  3. http://domain2.com/step3 - fails here with a 401.

Assuming this is not possible due to security concerns I thought I could just make call 1, extract the step2 Location, make call 2, extract the step 3 Location, make call 3. And before each add the Authorization header.

So is it possible to prevent specific calls following redirects so I can attempt this.

Fixed the HeaderParams.

headerParams = {
     headers: {
      'Content-Type':'application/x-www-form-urlencoded',
       'Accept':'*/*',
       'Authorization':'Basic XXXXXXXXXXXXXXXXXXX',
     },
  redirects: 0,
  };

I did find an option { redirects: 0} but when set doesn’t seem to work…

Payload = 'Some PayLoad, Some payload, some payload';
  headerParams = {
     headers: {
      'Content-Type':'application/x-www-form-urlencoded',
       'Accept':'*/*',
       'Authorization':'Basic XXXXXXXXXXXXXXXXXXX',
     },
  };

  urlResponse = http.post('domain1.com/login/callback',Payload,headerParams,{ redirects: 0});
  //console.log(urlResponse.body);
    urlResponseCheck = check(urlResponse, {
    'status is 200': (r) => r.status === 200,                     // contains http 200 OK
   // 'response body': (r) => r.body.indexOf('nextToGo') !== -1,   // constains string nextToGo OK
  });

I see that you solved the issue yourself, but just in case anyone stumbles on this in the future, the redirects option has to be on the same level as the headers in the request parameters: Params
