Struct oxide_auth::endpoint::AccessTokenFlow

pub struct AccessTokenFlow<E, R> where
    E: Endpoint<R>,
    R: WebRequest,  { /* fields omitted */ }

Offers access tokens to authenticated third parties.

After having received an authorization code from the resource owner, a client must directly contact the OAuth endpoint–authenticating itself–to receive the access token. The token is then used as authorization in requests to the resource. This request MUST be protected by TLS.

Client credentials can be allowed to appear in the request body instead of being required to be passed as HTTP Basic authorization. This is not recommended and must be enabled explicitely. See allow_credentials_in_body for details.

Methods

impl<E, R> AccessTokenFlow<E, R> where
    E: Endpoint<R>,
    R: WebRequest, 

pub fn prepare(endpoint: E) -> Result<Self, E::Error>

Check that the endpoint supports the necessary operations for handling requests.

Binds the endpoint to a particular type of request that it supports, for many implementations this is probably single type anyways.

Panics

Indirectly execute may panic when this flow is instantiated with an inconsistent endpoint, for details see the documentation of Endpoint and execute. For consistent endpoints, the panic is instead caught as an error here.

pub fn allow_credentials_in_body(&mut self, allow: bool)

Credentials in body should only be enabled if use of HTTP Basic is not possible.

Allows the request body to contain the client_secret as a form parameter. This is NOT RECOMMENDED and need not be supported. The parameters MUST NOT appear in the request URI itself.

Thus support is disabled by default and must be explicitely enabled.

pub fn execute(&mut self, request: R) -> Result<R::Response, E::Error>

Use the checked endpoint to check for authorization for a resource.

Panics

When the registrar, authorizer, or issuer returned by the endpoint is suddenly None when previously it was Some(_).
