pub struct OAuth2Client {
    pub client_id: String,
    pub authorization_endpoint: String,
    pub scopes: Vec<String>,
    pub use_pkce: bool,
    /* private fields */
}

OAuth2 client for authorization code flow.

Fields

client_id: String

Client ID from provider.

authorization_endpoint: String

Authorization endpoint.

scopes: Vec<String>

Scopes to request.

use_pkce: bool

Use PKCE for additional security.

Implementations

impl OAuth2Client

pub fn new( client_id: impl Into<String>, client_secret: impl Into<String>, authorization_endpoint: impl Into<String>, token_endpoint: impl Into<String>, ) -> Self

Create new OAuth2 client.

pub fn with_scopes(self, scopes: Vec<String>) -> Self

Set scopes for request.

pub const fn with_pkce(self, enabled: bool) -> Self

Enable PKCE protection.

pub fn authorization_url(&self, redirect_uri: &str) -> AuthorizationRequest

Generate authorization URL.

Returns an AuthorizationRequest containing the URL, the CSRF state value (must be stored and verified at callback), and an optional PKCE challenge (when use_pkce = true; the code_verifier must be stored and sent during token exchange).

pub async fn exchange_code( &self, code: &str, redirect_uri: &str, ) -> Result<TokenResponse, String>

Exchange authorization code for tokens.

Errors

Returns an error if the HTTP request to the token endpoint fails or the response cannot be parsed as a TokenResponse.

pub async fn refresh_token( &self, refresh_token: &str, ) -> Result<TokenResponse, String>

Refresh access token using a refresh token.

Errors

Propagates errors from the token endpoint request (network failure, non-2xx HTTP status, oversized response body, or JSON parse error).
