Add Header

[danwfreeman]

When using the WPT web UI the addHeader method works great.

When using the node wrapper program I cannot get it to work.

This is the syntax I use in the WPT UI which works:
addHeader X-header: someheader
navigate https://some.url.com

In the node program it looks like this:

var script = wpt.scriptToString([
{addHeader:[‘X-Header:’, ‘someheader’]},
{navigate: "https://some.url.com"}
])

wpt.runTest(script, {"location": "us-west-2", "connectivity": "Cable"}, function(err, data) {
...
});

The headers do not show up in the requests when viewing the results on the WPT web UI

Is this disabled from the wrapper program, how can I get it to work?

Thanks,
Dan

Kind of have the same problem with the setCookie i can confirm the test runs as a scripted test but besides the fact that it takes forever to run the test, it does also discard the header/cookie information

var script = wpt.scriptToString([
  {setCookie: [ 'example-url.com', 'cookie_name=cookie_value']},
  {navigate: 'http://example-url.com'}
]);

wpt.runTest( script, options_wpt,  function( err, data ) {
  ...

@7Ds7 does it work if you include the scheme, e.g.:

{setCookie: [ 'http://example-url.com', 'cookie_name=cookie_value']}

same issue here, and the customHeaders param allowed in the UI is not supported here as well (i couldn't find it between the mapping). @marcelduran any idea on why?

I just tried to use customHeaders too, but notice it's not supported and not present in the mapping.js file.

Hello from 2024. This is still actual. I console logged the result of scriptToString method, I copied it in UI and setHeader works great. However, from code, it's not supported?? as I see in logs header has blank value :( Why is this problem still active. for 9 years.

I've been using the Lighthouse node program from Google directly and it works great, it's what WPT uses under the covers, so I think better to just bypass WPT anyway. Unless there is some extraordinary feature you need from WPT?
Most features can be coded up in Lighthouse anyway

Thanks @danwfreeman. I think I will start using Lighthouse as well. Just push HTML report to S3 and reference it inside the reports. Nice to know, I will save some $$. Shame on WPT team lol. Losing clients over 9-year-old-still-open-issues

Hello there! Merry Christmas! Maybe Santa can bring us the solution for this ticket? I need it for add headers to the lighthouse tests. Thanks!
