/**
* Response from Authlete's {@code /auth/token} API.
*
*
* Authlete's {@code /auth/token} API returns JSON which can
* be mapped to this class. The service implementation should retrieve the
* value of {@code "action"} from the response and take the following steps
* according to the value.
*
*
*
* - {@link Action#INVALID_CLIENT INVALID_CLIENT}
* -
*
* When the value of {@code "action"} is {@code "INVALID_CLIENT"}, it means
* that authentication of the client failed. In this case, the HTTP status
* of the response to the client application is either {@code "400 Bad
* Request"} or {@code "401 Unauthorized"}. This requirement comes from
* RFC 6749, 5.2.
* Error Response. The description about {@code "invalid_client"} shown
* below is an excerpt from RFC 6749.
*
*
*
* invalid_client-
*
* Client authentication failed (e.g., unknown client, no client
* authentication included, or unsupported authentication method).
* The authorization server MAY return an HTTP 401 (Unauthorized)
* status code to indicate which HTTP authentication schemes are
* supported. If the client attempted to authenticate via the
* "Authorization" request header field, the authorization server
* MUST respond with an HTTP 401 (Unauthorized) status code and
* include the "WWW-Authenticate" response header field matching the
* authentication scheme used by the client.
*
*
*
*
*
* In either case, the JSON string returned by {@link #getResponseContent()}
* can be used as the entity body of the response to the client application.
*
*
*
* The following illustrate the response which the service implementation
* should generate and return to the client application.
*
*
*
* HTTP/1.1 400 Bad Request
* Content-Type: application/json
* Cache-Control: no-store
* Pragma: no-cache
*
* (The value returned from {@link #getResponseContent()})
*
*
* HTTP/1.1 401 Unauthorized
* WWW-Authenticate: (challenge)
* Content-Type: application/json
* Cache-Control: no-store
* Pragma: no-cache
*
* (The value returned from {@link #getResponseContent()})
*
*
* - {@link Action#INTERNAL_SERVER_ERROR INTERNAL_SERVER_ERROR}
* -
*
* When the value of {@code "action"} is {@code "INTERNAL_SERVER_ERROR"},
* it means that the request from the service implementation
* ({@link AuthorizationIssueRequest}) was wrong or that an error occurred
* in Authlete.
*
*
*
* In either case, from the viewpoint of the client application, it is an
* error on the server side. Therefore, the service implementation should
* generate a response to the client application with the HTTP status of
* {@code "500 Internal Server Error"}.
*
*
*
* {@link #getResponseContent()} returns a JSON string which describes
* the error, so it can be used as the entity body of the response.
*
*
*
* The following illustrates the response which the service implementation
* should generate and return to the client application.
*
*
*
* HTTP/1.1 500 Internal Server Error
* Content-Type: application/json
* Cache-Control: no-store
* Pragma: no-cache
*
* (The value returned from {@link #getResponseContent()})
*
*
* - {@link Action#BAD_REQUEST BAD_REQUEST}
* -
*
* When the value of {@code "action"} is {@code "BAD_REQUEST"}, it means
* that the request from the client application is invalid.
*
*
*
* The HTTP status of the response returned to the client application
* must be {@code "400 Bad Request"} and the content type must be
* {@code "application/json"}.
*
*
*
* {@link #getResponseContent()} returns a JSON string which describes
* the error, so it can be used as the entity body of the response.
*
*
*
* The following illustrates the response which the service implementation
* should generate and return to the client application.
*
*
*
* HTTP/1.1 400 Bad Request
* Content-Type: application/json
* Cache-Control: no-store
* Pragma: no-cache
*
* (The value returned from {@link #getResponseContent()})
*
*
* - {@link Action#PASSWORD PASSWORD}
* -
*
* When the value of {@code "action"} is {@code "PASSWORD"}, it means that
* the request from the client application is valid and {@code grant_type}
* is {@code "password"}. That is, the flow is
* "Resource Owner
* Password Credentials".
*
*
*
* In this case, {@link #getUsername()} returns the value of {@code "username"}
* request parameter and {@link #getPassword()} returns the value of {@code
* "password"} request parameter which were contained in the token request
* from the client application. The service implementation must validate the
* credentials of the resource owner (= end-user) and take either of the
* actions below according to the validation result.
*
*
*
* -
*
* When the credentials are valid, call Authlete's {@code
* /auth/token/issue} API to generate an access token for the client
* application. The API requires {@code "ticket"} request parameter and
* {@code "subject"} request parameter.
* Use the value returned from {@link #getTicket()} method as the value
* for {@code "ticket"} parameter.
*
*
*
* The response from {@code /auth/token/issue} API ({@link
* TokenIssueResponse}) contains data (an access token and others)
* which should be returned to the client application. Use the data
* to generate a response to the client application.
*
*
* -
*
* When the credentials are invalid, call Authlete's {@code
* /auth/token/fail} API with {@code reason=}{@link
* TokenFailRequest.Reason#INVALID_RESOURCE_OWNER_CREDENTIALS
* INVALID_RESOURCE_OWNER_CREDENTIALS} to generate an error response
* for the client application. The API requires {@code "ticket"}
* request parameter. Use the value returned from {@link #getTicket()}
* method as the value for {@code "ticket"} parameter.
*
*
*
* The response from {@code /auth/token/fail} API ({@link
* TokenFailResponse}) contains error information which should be
* returned to the client application. Use it to generate a response
* to the client application.
*
*
*
*
* - {@link Action#OK OK}
* -
*
* When the value of {@code "action"} is {@code "OK"}, it means that
* the request from the client application is valid and an access token,
* and optionally an ID token, is ready to be issued.
*
*
*
* The HTTP status of the response returned to the client application
* must be {@code "200 OK"} and the content type must be
* {@code "application/json"}.
*
*
*
* {@link #getResponseContent()} returns a JSON string which contains
* an access token (and optionally an ID token), so it can be used as
* the entity body of the response.
*
*
*
* The following illustrates the response which the service implementation
* should generate and return to the client application.
*
*
*
* HTTP/1.1 200 OK
* Content-Type: application/json
* Cache-Control: no-store
* Pragma: no-cache
*
* (The value returned from {@link #getResponseContent()})
*
*
*
* @see RFC 6749, OAuth 2.0
