我已经尝试了所有可能的设置，但仍然无法解决这个问题。我用express nodejs创建了我的服务器，并将其部署在Heroku上。在我的localHost（服务器和客户端）上，一切都能完美运行，但当服务器在Heroku上时就不行了。
我在stackoverflow上查看了这个问题的所有答案，但我仍然无法解决它='（
const cors = require('cors');
const app = express();
mongoose.connect( process.env.MONGO_URL)
.then(() => {
console.log('Connected to database!');
})
.catch(() => {
console.log('DB Connection failed!');
});
app.use(cors({origin: true, credentials: true}));
app.use(express.json());
app.use(AUTH, authRoute);
app.use(USERS, userRoute);
app.use(PRODUCTS, productRoute);
app.use(CARTS, cartRoute);
app.use(ORDERS, orderRoute);
app.use(CHECKOUT, stripeRoute);
app.get('/', (req, res) => {
res.send('Hello to Greensai Updated!');
});
app.listen(process.env.PORT || 5000, () => {
console.log('Server started on port 5000');
});

Try using this code right in between app.use(express.json()); and app.use(AUTH, authRoute);
This should allow your server to send a response back to the client.
