Google Auth Library Client - Class OAuth2 (1.46.0)

Reference documentation and code samples for the Google Auth Library Client class OAuth2.

OAuth2 supports authentication by OAuth2 2-legged flows.

It primary supports

• service account authorization
• authorization where a user already has an access token

Create a new OAuthCredentials.

The configuration array accepts various options

• authorizationUri The authorization server's HTTP endpoint capable of authenticating the end-user and obtaining authorization.

• tokenCredentialUri The authorization server's HTTP endpoint capable of issuing tokens and refreshing expired tokens.

• clientId A unique identifier issued to the client to identify itself to the authorization server.

• clientSecret A shared symmetric secret issued by the authorization server, which is used to authenticate the client.

• scope The scope of the access request, expressed either as an Array or as a space-delimited String.

• state An arbitrary string designed to allow the client to maintain state.

• redirectUri The redirection URI used in the initial request.

• username The resource owner's username.

• password The resource owner's password.

• issuer Issuer ID when using assertion profile

• audience Target audience for assertions

• expiry Number of seconds assertions are valid for

• signingKey Signing key when using assertion profile

• signingKeyId Signing key id when using assertion profile

• refreshToken The refresh token associated with the access token to be refreshed.

• accessToken The current access token for this client.

• idToken The current ID token for this client.

• extensionParams When using an extension grant type, this is the set of parameters used by that extension.

• codeVerifier The code verifier for PKCE for OAuth 2.0.

• resource The target service or resource where the client ntends to use the requested security token.

• subjectTokenFetcher A fetcher for the "subject_token", which is a security token that represents the identity of the party on behalf of whom the request is being made.

• subjectTokenType An identifier that indicates the type of the security token in the subjectToken parameter.

• actorToken A security token that represents the identity of the acting party.

• actorTokenType An identifier for the representation of the issued security token.

Verifies the idToken if present.

• if none is present, return null
• if present, but invalid, raises DomainException.
• otherwise returns the payload in the idtoken as a PHP object.

The behavior of this method varies depending on the version of firebase/php-jwt you are using. In versions 6.0 and above, you cannot provide multiple $allowed_algs, and instead must provide an array of Key objects as the $publicKey.

Obtains the encoded jwt from the instance data.

Generates a request for token credentials.

Fetches the auth tokens based on the current state.

Obtains a key that can used to cache the results of #fetchAuthToken.

Gets this instance's SubjectTokenFetcher

Parses the fetched tokens.

Updates an OAuth 2.0 client.

Example:

 $oauth->updateToken([
    'refresh_token' => 'n4E9O119d',
    'access_token' => 'FJQbwq9',
    'expires_in' => 3600
]); 

Builds the authorization Uri that the user should be redirected to.

Generates a random 128-character string for the "code_verifier" parameter in PKCE for OAuth 2.0. This is a cryptographically random string that is determined using random_int, hashed using "hash" and sha256, and base64 encoded.

When this method is called, the code verifier is set on the object.
