Method Documentation

◆ authorizationRequestURL()

- (NSURL *) authorizationRequestURL

Constructs the request URI by adding the request parameters to the query component of the authorization endpoint URI using the "application/x-www-form-urlencoded" format.

Returns: A URL representing the authorization request.

See also: https://tools.ietf.org/html/rfc6749#section-4.1.1

◆ codeChallengeS256ForVerifier:()

Creates a PKCE S256 codeChallenge from the codeVerifier.

Parameters

codeVerifier The code verifier from which the code challenge will be derived.

Returns: The generated code challenge.

Generate a secure code verifier to pass into this method with generateCodeVerifier. The matching codeChallengeMethod for codeChallenges created by this method is OIDOAuthorizationRequestCodeChallengeMethodS256.

Property Documentation

◆ additionalParameters

- (NSDictionary<NSString *, NSString *>*) additionalParameters

readnonatomicassign

The client's additional authorization parameters.

See also: https://tools.ietf.org/html/rfc6749#section-3.1

◆ clientID

- (NSString*) clientID

readnonatomicassign

The client identifier.

Remarks: client_id

See also: https://tools.ietf.org/html/rfc6749#section-2.2

◆ clientSecret

- (NSString*) clientSecret

readnonatomicassign

The client secret.

Remarks: client_secret The client secret is used to prove that identity of the client when exchaning an authorization code for an access token. The client secret is not passed in the authorizationRequestURL. It is only used when exchanging the authorization code for an access token.

See also: https://tools.ietf.org/html/rfc6749#section-2.3.1

◆ codeChallenge

- (NSString*) codeChallenge

readnonatomicassign

The PKCE code challenge, derived from codeVerifier.

Remarks: code_challenge

See also: https://tools.ietf.org/html/rfc7636#section-4.2

◆ codeChallengeMethod

- (NSString*) codeChallengeMethod

readnonatomicassign

The method used to compute the codeChallenge.

Remarks: code_challenge_method

See also: https://tools.ietf.org/html/rfc7636#section-4.3

◆ codeVerifier

- (NSString*) codeVerifier

readnonatomicassign

The PKCE code verifier.

Remarks: code_verifier The code verifier itself is not included in the authorization request that is sent on the wire, but needs to be in the token exchange request. tokenExchangeRequest (OIDAuthorizationResponse) will create a OIDTokenRequest that includes this parameter automatically.

See also: https://tools.ietf.org/html/rfc7636#section-4.1

◆ configuration

- (OIDServiceConfiguration*) configuration

readnonatomicassign

The service's configuration.

Remarks: This configuration specifies how to connect to a particular OAuth provider. Configurations may be created manually, or via an OpenID Connect Discovery Document.

◆ redirectURL

- (NSURL*) redirectURL

readnonatomicassign

The client's redirect URI.

Remarks: redirect_uri

See also: https://tools.ietf.org/html/rfc6749#section-3.1.2

◆ responseType

- (NSString*) responseType

readnonatomicassign

The expected response type.

Remarks: response_type Generally 'code' if pure OAuth, otherwise a space-delimited list of of response types including 'code', 'token', and 'id_token' for OpenID Connect.

See also: https://tools.ietf.org/html/rfc6749#section-3.1.1; http://openid.net/specs/openid-connect-core-1_0.html#rfc.section.3

◆ scope

- (NSString*) scope

readnonatomicassign

The value of the scope parameter is expressed as a list of space-delimited, case-sensitive strings.

Remarks: scope

See also: https://tools.ietf.org/html/rfc6749#section-3.3

◆ state

- (NSString*) state

readnonatomicassign

An opaque value used by the client to maintain state between the request and callback.

Remarks: state If this value is not explicitly set, this library will automatically add state and perform appropriate validation of the state in the authorization response. It is recommended that the default implementation of this parameter be used wherever possible. Typically used to prevent CSRF attacks, as recommended in RFC6819 Section 5.3.5.
