app.get('/', function(req, res) { 
    res.render('index.ejs'); 
}); 

app.get('/host', function(req, res) { 
    var sessionId = app.get('sessionId'), 
     // generate a fresh token for this client 
     token = opentok.generateToken(sessionId, { role: 'moderator' }); 

    res.json('host.ejs', { 
    apiKey: apiKey, 
    sessionId: sessionId, 
    token: token 
    });

jak kłody, dodaję stan i zmiany

res.status(200).json 

nadal nie działa, proszę o pomoc, dzięki

Answer 1

res.json([body]) 

Wyślij odpowiedź JSON. Ta metoda jest identyczna z res.send(), gdy przekazany jest obiekt lub tablica.

res.json(null) 
res.json({ user: 'tobi' }) 
res.status(500).json({ error: 'message' }) 

Dla usługi json API prawdopodobnie nie ma potrzeby renderowania czegokolwiek.

Answer 2

res.json zajmuje tylko przedmiot, po prostu usunąć 'host.ejs',

res.json({ 
    apiKey: apiKey, 
    sessionId: sessionId, 
    token: token 
});
