Sets up a Plex Media Server MITMd by mitmproxy with the aim of learning more about how the
PMS talks to Plex.tv and other upstream services (metadata, avatars, analytics, etc).
This is in service of project I am building which needs to talk to the undocumented Plex.tv APIs. You are welcome to use it too.
See docs/API.md for some of the requests I'm trying to document.
Make sure you have Firefox installed, as the snoop.rb script opens a Firefox instance configured with the proxy so
that you can snoop Plex Web traffic too.
$ ruby ./snoop.rbThe docker-compose.yml sets a default view filter for mitmproxy to hide some noisy and irrelevant requests:
! ( ~a | ~m OPTIONS | ~t html | ~t woff2 | ~c 301 | ~d google.com | ~d facebook | ~d gstatic.com | ~d mozilla | ~d firefox | ~d sentry | ~d transifex.net | ~d digicert | /wp-content/ | resources-cdn )
This hides all assets (JS, CSS, images, etc), all HTML responses (I only care about API calls), redirects, and several domains related to the auth pages that Plex Web shows or Firefox internals.
You'll have to remove it from docker-compose.yml, edit it to what you want, or use "Edit Options" after mitmweb
boots to see requests which are hidden.
Additionally, it can be helpful to delineate PMS requests from Plex Web requests. I don't know if I can auto-configure this, but setting the "Highlight" field to the following filter will highlight non-Firefox requests:
! ~hq "User-Agent.*Firefox"
