HTTPRequest.headers() method

An object with HTTP headers associated with the request. All header names are lower-case.

Signature

class HTTPRequest {
  abstract headers(): Record<string, string>;
}

Returns:

Record<string, string>

Remarks

Under CDP, page.on('request') fires before the browser's network stack attaches all headers (such as accept, accept-encoding, cookie, host, and sec-fetch-*). The full set of headers is populated asynchronously and is available by the time page.on('response') or page.on('requestfinished') fires.
