Cannot get data from session

[davidquintard]

Hi there, i'm using express-session with routing-controllers and i can't get data from session.

var options = {
    host: process.env.MARIADB_HOST,
    port: process.env.MARIADB_PORT,
    user: process.env.MARIADB_USER,
    password: process.env.MARIADB_PASS,
    database: process.env.MARIADB_NAME
};

var sessionStore = new MySQLStore(options);

expressApp.use(session({
    key: 'session_cookie_name',
    secret: 'session_cookie_secret',
    store: sessionStore,
    resave: false,
    saveUninitialized: false
}));

@Post("/login")
    login(@Session() session: Express.Session, @Body() body: any, @Req() request: Request) {
....
        const authService = Container.get(AuthService);
        return authService.save(membre, session);
    }

save(membre: Membre, session: Express.Session) {
....
            session.membre = {}
            session.membre['id'] = membre.getId();   
....
}

After that, session is correctly stored in database:

{"cookie":{"originalMaxAge":null,"expires":null,"secure":false,"httpOnly":true,"path":"/","sameSite":false},"membre":{"id":204658}}

But when i call another page like this:

@Get("/liste/skip/:skip/take/:take")
    liste(@Param("skip") skip: number, @Param("take") take: number, @Session() session: Express.Session, @Req() request: Request)
    {
        console.log(session)
        return  this.candidatRepository.createQueryBuilder("c")
                .leftJoinAndSelect('c.annonce', 'ann')
                .leftJoinAndSelect('c.adresse', 'adr')
                .innerJoinAndSelect('adr.country', 'co')
                .leftJoinAndSelect('c.galeriesPhoto', 'gal', 'gal.acces=1')
                .leftJoinAndSelect('gal.photos', 'cp', 'cp.ordre=1')
                .where("c.membre=:membre")
                .andWhere("c.id_site=:id_site")
                .setParameter("membre", session.membre.id) => TypeError: Cannot read property 'id' of undefined
                .setParameter("id_site", Container.get(ConfigService).get('HOSTID'))
                .skip(skip)
                .take(take)
                .getMany()
                .then(function(candidatures) {
                    return candidatures;
                })
                .catch(function(error) {
                    return {
            'error': i18n.__("Une erreur est survenue! ") // an error occured
            }; 
                }); 
    }

... session is not retrieved (TypeError: Cannot read property 'id' of undefined)

console.log(session) :

Session {
  cookie:
   { path: '/',
     _expires: null,
     originalMaxAge: null,
     httpOnly: true,
     secure: false,
     sameSite: false } }

This error occurs when my ionic app calls my express api by ajax xmlHttpRequest. But when i call this api directly from my browser: http://localhost:3000/candidat/candidature/liste/skip/0/take/20 It works fine, i get response without error.

Did i miss something ?

When making the AJAX request, make sure to set the withCredentials property to true.
