GetAuthorizeUri(OAuthResponseType, string, string, string, bool, bool, string, bool, TokenAccessType, string[], IncludeGrantedScopes)

Gets the URI used to start the OAuth2.0 authorization flow. Passes in codeChallenge generated in this class.

Declaration

public Uri GetAuthorizeUri(OAuthResponseType oauthResponseType, string clientId, string redirectUri = null, string state = null, bool forceReapprove = false, bool disableSignup = false, string requireRole = null, bool forceReauthentication = false, TokenAccessType tokenAccessType = TokenAccessType.Legacy, string[] scopeList = null, IncludeGrantedScopes includeGrantedScopes = IncludeGrantedScopes.None)

Parameters

Type	Name	Description
OAuthResponseType	oauthResponseType	The grant type requested, either `Token` or `Code`.
string	clientId	The apps key, found in the App Console.
string	redirectUri	Where to redirect the user after authorization has completed. This must be the exact URI registered in the App Console; even `localhost` must be listed if it is used for testing. A redirect URI is required for a token flow, but optional for code. If the redirect URI is omitted, the code will be presented directly to the user and they will be invited to enter the information in your app.
string	state	Up to 500 bytes of arbitrary data that will be passed back to `redirectUri`. This parameter should be used to protect against cross-site request forgery (CSRF).
bool	forceReapprove	Whether or not to force the user to approve the app again if they've already done so. If `false` (default), a user who has already approved the application may be automatically redirected to `redirectUri`If `true`, the user will not be automatically redirected and will have to approve the app again.
bool	disableSignup	When `true` (default is `false`) users will not be able to sign up for a Dropbox account via the authorization page. Instead, the authorization page will show a link to the Dropbox iOS app in the App Store. This is only intended for use when necessary for compliance with App Store policies.
string	requireRole	If this parameter is specified, the user will be asked to authorize with a particular type of Dropbox account, either work for a team account or personal for a personal account. Your app should still verify the type of Dropbox account after authorization since the user could modify or remove the require_role parameter.
bool	forceReauthentication	If `true`, users will be signed out if they are currently signed in. This will make sure the user is brought to a page where they can create a new account or sign in to another account. This should only be used when there is a definite reason to believe that the user needs to sign in to a new or different account.
TokenAccessType	tokenAccessType	Determines the type of token to request. See TokenAccessType for information on specific types available. If none is specified, this will use the legacy type.
string[]	scopeList	list of scopes to request in base oauth flow. If left blank, will default to all scopes for app.
IncludeGrantedScopes	includeGrantedScopes	which scopes to include from previous grants. Note: if this user has never linked the app, include_granted_scopes must be None.

Returns

Type	Description
Uri	The uri of a web page which must be displayed to the user in order to authorize the app.

ProcessCodeFlowAsync(string, string, string, HttpClient)

Processes the second half of the OAuth 2.0 code flow. Uses the codeVerifier created in this class to execute the second half.

Declaration

public Task<OAuth2Response> ProcessCodeFlowAsync(string code, string appKey, string redirectUri = null, HttpClient client = null)

Parameters

Type	Name	Description
string	code	The code acquired in the query parameters of the redirect from the initial authorize url.
string	appKey	The application key, found in the App Console.
string	redirectUri	The redirect URI that was provided in the initial authorize URI, this is only used to validate that it matches the original request, it is not used to redirect again.
HttpClient	client	An optional http client instance used to make requests.

Returns

Type	Description
Task<OAuth2Response>	The authorization response, containing the access token and uid of the authorized user.

Parameters

Type	Name	Description
