allow HTTP request headers to be customized for each video in queue
Browse files Browse the repository at this point in the history 
* POST data sent in requests to "/play" and "/queue" API endpoints:
  - now recognizes the keys:
    * req-header
    * drm-header
  - ex:
      req-header: Referer: http://example.com/videos.html
      req-header: Origin:  http://example.com
      drm-header: Authorization: Bearer <TOKEN>
* Intents
  - which are:
    * used to start StartNetworkingServiceActivity
    * and forwarded to NetworkingService
  - can now include the extras:
    * reqHeader
    * drmHeader
  - which can be data type:
    * String[]
    * String
  - and each String is formatted:
    * "header-name: header-value"
* POST data sent in requests to "/start-activity" API endpoint:
  - can configure these Intent extras
    * extra-reqHeader
    * extra-drmHeader
  - ex:
      extra-reqHeader: Referer: http://example.com/videos.html
      extra-reqHeader: Origin:  http://example.com
      extra-drmHeader: Authorization: Bearer <TOKEN>

notes:
* the ability to configure "referer" is now redundant
  - keys:
    * POST data: referer
    * Intent extra: referUrl
  - this feature is legacy, and kept to avoid breaking userspace
* DRM headers are only used when
  both DRM scheme and DRM license server URL are provided
* ExoAirPlayer is configured with a default "User-Agent"
  - which impersonates a recent version of Chrome for Windows desktop
  - custom request headers can override this default value
