Class AuthorizationCodeFlow

Thread-safe OAuth 2.0 authorization code flow that manages and persists end-user credentials.

This is designed to simplify the flow in which an end-user authorizes the application to access their protected data, and then the application has access to their data based on an access token and a refresh token to refresh that access token when it expires.

Parameters

Type	Name	Description
string	userId	User identifier.
string	code	Authorization code received from the authorization server.
string	redirectUri	Redirect URI which is used in the token request.
System.Threading.CancellationToken	taskCancellationToken	Cancellation token to cancel operation.

Returns

Type	Description
System.Threading.Tasks.Task<TResult><TokenResponse>	Token response which contains the access token.

FetchTokenAsync(string, TokenRequest, CancellationToken)

Declaration

public Task<TokenResponse> FetchTokenAsync(string userId, TokenRequest request, CancellationToken taskCancellationToken)

Parameters

Type	Name	Description
string	userId	User identifier.
TokenRequest	request	Token request.
System.Threading.CancellationToken	taskCancellationToken	Cancellation token to cancel operation.

Returns

Type	Description
System.Threading.Tasks.Task<TResult><TokenResponse>	Token response with the new access token.

LoadTokenAsync(string, CancellationToken)

Asynchronously loads the user's token using the flow's Google.Apis.Util.Store.IDataStore.

Declaration

public Task<TokenResponse> LoadTokenAsync(string userId, CancellationToken taskCancellationToken)

Parameters

Type	Name	Description
string	userId	User identifier
System.Threading.CancellationToken	taskCancellationToken	Cancellation token to cancel operation

Returns

Type	Description
System.Threading.Tasks.Task<TResult><TokenResponse>	Token response

RefreshTokenAsync(string, string, CancellationToken)

Asynchronously refreshes an access token using a refresh token.

Declaration

public Task<TokenResponse> RefreshTokenAsync(string userId, string refreshToken, CancellationToken taskCancellationToken)

Parameters

Type	Name	Description
string	userId	User identifier.
string	refreshToken	Refresh token which is used to get a new access token.
System.Threading.CancellationToken	taskCancellationToken	Cancellation token to cancel operation.

Returns

Type	Description
System.Threading.Tasks.Task<TResult><TokenResponse>	Token response which contains the access token and the input refresh token.

RevokeTokenAsync(string, string, CancellationToken)

Asynchronously revokes the specified token. This method disconnects the user's account from the OAuth 2.0 application. It should be called upon removing the user account from the site.

Declaration

public virtual Task RevokeTokenAsync(string userId, string token, CancellationToken taskCancellationToken)

Parameters

Type	Name	Description
string	userId	User identifier.
string	token	Access token to be revoked.
System.Threading.CancellationToken	taskCancellationToken	Cancellation token to cancel operation.

Returns

Type	Description
System.Threading.Tasks.Task	true if the token was revoked successfully.

Remarks

If revoking the token succeeds, the user's credential is removed from the data store and the user MUST authorize the application again before the application can access the user's private resources.

ShouldForceTokenRetrieval()

Indicates if a new token needs to be retrieved and stored regardless of normal circumstances.

Declaration

public virtual bool ShouldForceTokenRetrieval()

Returns

Type	Description
bool
