osu.API - unnoficial C# osu! api wrapper

This project is WIP and was made cause most availiable C# wrappers are unmantained and I needed something to use in my personal projects.

Project Structure

The Api is divided on the following namespaces

• osu.API.Data - Containss all data models.
• osu.API.Requests - Contains all requests (E.g. GetUserRequest)
• osu.API.Client - Contains helpers for talking to the api (E.g. ClientCredentialsGrant)

This project targets the V2 of the api exclusively

If need be, support for V1 could be worked later, but thats not currently planned.

Library Usage

//This will be simplified under osuClient, but thats not currently implemented

//Gets a token from the api
var token = await Authentication.OAuthClientCredentialsAsync(credentials, httpClient);

//Build a Request

//Names of Request classes **are** the canonical name given by the apidocumentation!
GetUserRequest userRequest = new(8945532,Gamemode.Mania, token.Token);

//Execute the request
var user = await userRequest.GetAsync(httpClient);

What is a Request?

A Rquest object is any call to the osu! endpoint, and a list of those requests are available on the official documentation. And those can be either authenticated or not.

They are represented by AuthenticatedRequest<T> and BaseRequest<T> on the lowest levels. Although you rarely will need to use those abstract classes since the project provides (Get|Post)Request<T> and Authenticated(Get|Post)Request<T> .

There's also interfaces for defining URL parameters and Query parameters to further simplify implementation.

The design as it curently stand is directly translatable from the oficial documentation. An example of that is provided below:

Get User

HTTP Request
GET /users/{user}/{mode?}

URL Parameters
Parameter  Status       Description
user       required	Id of the user.
mode       optional	GameMode. User default mode will be used if not specified.

Becomes:

public class GetUserRequest : AuthenticatedGetRequest<User> {
	public GetUserRequest(UserUrlParam user, string accessToken) : base(accessToken) {
		UrlParameters.Add(user);
	}

	public GetUserRequest(UserUrlParam user, ModeUrlParam mode, string accessToken) : base(accessToken) {
		UrlParameters.Add(user);
		UrlParameters.Add(mode);
	}
}

All of the html request handling and response parsing is done by AuthenticatedGetRequest.

Request Types

• GetRequest<T> - A generic GET request that does not require authentiaction
• AuthenticatedGetRequest<T> - A generic GET request that requires an acess token
• LazerRequest<T> - Dummy request that does nothing. Used exclusively by the osu!lazer client.
  Exists here for future proofing reasons (maybe the API will be opened to the public?). You can't even use them.

Wrappers for the following HTTP request types exist:

• GET POST

Examples on how to implement a request and all implemented requests are available under Requests/
