问题

Node js Rest API not working in the prod server. it is locally working fine.

server.js

var app = require('./app');
var http = require('http');
var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
var server = http.createServer(app);
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
function normalizePort(val) {
    var port = parseInt(val, 10);
    if (isNaN(port)) {
        return val;
    }
    if (port >= 0) {
        return port;
    }
    return false;
}
function onError(error) {
    if (error.syscall !== 'listen') {
        throw error;
    }
    var bind = typeof port === 'string' ? 'Pipe ' + port : 'Port ' + port;
    switch (error.code) {
        case 'EACCES':
            console.error(bind + ' requires elevated privileges');
            process.exit(1);
            break;
        case 'EADDRINUSE':
            console.error(bind + ' is already in use');
            process.exit(1);
            break;
        default:
            throw error;
    }
}
function onListening() {
    var addr = server.address();
    var bind = typeof addr === 'string' ? 'pipe ' + addr : 'port ' + addr.port;
    console.log('Listening on ' + bind);

回答1:

In your signup post request, you are using middleware as array, Please remove the third parenthesis and try again.

Your signup route should be,

router.post('/signup', verifySignUp.checkDuplicateUserNameOrEmail, controller.signup);

回答2:

if you are watching Maximillian course ,you could recheck the path of app module

var app = require('./app');

I think it should be

var app = require('./backend/app');

回答3:

Don't know, if you already have an answer, but i had the same problem.

The fix was to set the Websites & Domains -> Hosting Settings -> Preferred domain.

It was set to "www.domain.xy".

I set the domain "domain.xy" without "www" as preferred.

The problem was, that nginx redirects the requests from "domain.xy" to "www.domain.xy" with a redirect 301. Then the POST becomes a GET Request.

After this change a redirect wasn't executed anymore and i got my POST Request.
