Una risorsa Invitation in Classroom rappresenta un invito
per un utente a partecipare a un corso con un ruolo del corso specifico: studente, insegnante
o proprietario.
Ogni risorsa Invitation contiene i seguenti campi:
id: identificatore assegnato da Classroom per l'invito.
userId: l'ID dell'utente che è stato invitato al corso.
courseId: il corso a cui viene invitato l'utente.
role: il ruolo del corso che l'utente invitato avrà nel corso.
Creare un invito
Il metodo invitations.create() può essere utilizzato per invitare un utente a un corso
con un ruolo specifico. Includi la risorsaInvitation nel corpo della richiesta e specifica courseId, userId e role.
Invitationinvitation=null;try{/* Set the role the user is invited to have in the course. Possible values of CourseRole can be found here: https://developers.google.com/classroom/reference/rest/v1/invitations#courserole.*/Invitationcontent=newInvitation().setCourseId(courseId).setUserId(userId).setRole("TEACHER");invitation=service.invitations().create(content).execute();System.out.printf("User (%s) has been invited to course (%s).\n",invitation.getUserId(),invitation.getCourseId());}catch(GoogleJsonResponseExceptione){// TODO (developer) - handle error appropriatelyGoogleJsonErrorerror=e.getDetails();if(error.getCode()==404){System.out.printf("The course or user does not exist.\n");}throwe;}catch(Exceptione){throwe;}returninvitation;
Recuperare un invito
Recupera un invito specifico chiamando il metodo invitations.get() e specificando l'id dell'invito.
Invitationinvitation=null;try{invitation=service.invitations().get(id).execute();System.out.printf("Invitation (%s) for user (%s) in course (%s) retrieved.\n",invitation.getId(),invitation.getUserId(),invitation.getCourseId());}catch(GoogleJsonResponseExceptione){GoogleJsonErrorerror=e.getDetails();if(error.getCode()==404){System.out.printf("The invitation id (%s) does not exist.\n",id);}throwe;}catch(Exceptione){throwe;}returninvitation;
Accettare un invito
L'accettazione di un invito lo elimina e aggiunge l'utente invitato al corso con il ruolo specificato nell'invito. Accetta un invito chiamando il metodo invitations.accept() e specificando l'id dell'invito.
try{service.invitations().accept(id).execute();System.out.printf("Invitation (%s) was accepted.\n",id);}catch(GoogleJsonResponseExceptione){GoogleJsonErrorerror=e.getDetails();if(error.getCode()==404){System.out.printf("The invitation id (%s) does not exist.\n",id);}throwe;}catch(Exceptione){throwe;}
Eliminare un invito
L'unico modo per aggiornare un invito è eliminarlo e crearne uno
nuovo. Per eliminare l'invito, chiama il metodo invitations.delete()
e specifica id.
try{service.invitations().delete(id).execute();System.out.printf("Invitation (%s) was deleted.\n",id);}catch(GoogleJsonResponseExceptione){GoogleJsonErrorerror=e.getDetails();if(error.getCode()==404){System.out.printf("The invitation id (%s) does not exist.\n",id);}throwe;}catch(Exceptione){throwe;}
