Testing web server full stack with osu!

Jump to bottom

This is a guide to help ease the setup of a full development environment with

  • osu!
  • osu-web
  • osu-server-spectator

This will allow testing all operations including multiplayer, spectating, account creation etc.

Prerequisites

Initial setup

Basics

Make sure you have setup a client key. You can use it to populate DevelopmentEndpointConfiguration.cs in your osu! checkout (along with the endpoint URLs):

diff --git a/osu.Game/Online/DevelopmentEndpointConfiguration.cs b/osu.Game/Online/DevelopmentEndpointConfiguration.cs

         }
     }
 }

In osu-server-spectator, update the client ID in ConfigureJwtBearerOptions:

                 ValidateIssuer = false,
                 ValidIssuer = "https://osu.ppy.sh/"

Copy the set up osu!web oauth public key across to the spectator project:

$ cp osu-web/storage/oauth-public.key osu-server-spectator/osu.Server.Spectator/oauth-public.key

Now you can run osu-server-spectator in release configuration (debug/development should be avoided as it assigns random user IDs to any connected client, rather than their actual user IDs).

By default, osu-server-spectator will bind to local port 80. This may fail on desktop PCs (with a System.Net.Sockets.SocketException: Permission denied error), in which case you should change the port to a different one:

         }
     }

If the above change is made, spectatorServerRootUrl in DevelopmentEndpointConfiguration in the client must also be updated to match.

To make osu! work without https, you will need to adjust a few files for the time being:

At this point, osu will connect to and consume osu-web API endpoints, as well connect to the osu-server-spectator instance. However, more specialised flows such as score submissions will not work yet.

Score submission

In order to be able to submit any scores in such a local environment, set the following environment variable in osu-web/.env:

CLIENT_CHECK_VERSION=false

This skips the client compatibility check on the osu-web side that would normally happen in production to ensure that the build the score was set on is a known build.

Replays

osu-server-spectator is responsible for storing replays for all scores captured using the client. To enable the replay-capturing flow in a way that works with osu-web and the client, the following steps must be performed:

In osu-web, enable local replay storage by adding

SCORE_REPLAYS_STORAGE=local

to osu-web/.env.

In osu-server-spectator, apply the following diff:

to allow downloading the replay over HTTP.

After this, it should be possible to download replays set via the lazer client and recorded by osu-server-spectator, both via osu-web and the lazer client.

Running

  • start osu-web 
$ cd osu-web
$ ./docker-composer up
  • start osu-server-spectator in release configuration (release config is required to connect to the osu-web instance)
$ cd osu-server-spectator
$ dotnet run -c Release
  • start osu! in debug configuration (via IDE or otherwise)
    • you can use the --debug-client-id={number} argument with different IDs for running as many osu! instances for testing as desired.
