GSS.Authorization.OAuth

OAuth authorized HttpClient, friendly with HttpClientFactory

NuGet Packages

Installation

# OAuth 1.0 protocol
dotnet add package GSS.Authorization.OAuth.HttpClient

# OAuth 2.0 protocol
dotnet add package GSS.Authorization.OAuth2.HttpClient

Getting started

// OAuth 1.0
services.AddOAuthHttpClient<OAuthHttpClient>((_, options) =>
{
    options.ClientCredentials = new OAuthCredential("client-id", "client-secret");
    options.TokenCredentials = new OAuthCredential("token-id", "token-secret");
});

// OAuth 2.0
services.AddOAuth2HttpClient<OAuth2HttpClient, ClientCredentialsAuthorizer>((_, options) =>
{
    options.AccessTokenEndpoint = new Uri("https://example.com/oauth2/token");
    options.ClientId = "client-id";
    options.ClientSecret = "client-secret";
});

Each client name owns its own credential and, for OAuth 2.0, its own cached access token.

Limits

OAuth 1.0 protocol

Only HMAC-SHA1 and PLAINTEXT signature methods are provided. Implement GSS.Authorization.OAuth.IRequestSigner to support more — see writing your own request signer for the contract it has to honour.
Only the InteractiveConsoleAuthorizer grant flow is provided. Implement GSS.Authorization.OAuth.IAuthorizer to support more.

OAuth 2.0 protocol

Only the Client-Credentials and Resource-Owner-Credentials grant flows are provided. Implement GSS.Authorization.OAuth2.IAuthorizer to support more.
