Cannot post membership/login/submit - node.js

Question

I have some code to create an account and have a login page and say true or false if you entered the correct details but instead it says 'Cannot post /membership/login/submit'.
my main.js code (the html files are basic and the forms are just standard tags with an action and a method, tell me if you want these)
var app = require('express')();
var http = require('http').Server(app);
var httpuse = require('http');
var io = require('socket.io')(http);
var MongoClient = require('mongodb').MongoClient;
var users = require(__dirname + '/local_js/users.js');
var public = __dirname + "/www/";
var bodyParser = require('body-parser')
var url = "mongodb://localhost:27017/";
const bcrypt = require('bcrypt');
var needle = require('needle');
const saltRounds = 10;
app.use(bodyParser.urlencoded({ extended: false }));
function rand(n) {
Math.floor(Math.random() * (n+1));
}
function getToken(hashedpass, user) {
return hashedpass+"_._"+user;
}
app.get('/', function(req, res){
res.sendFile(public + 'index.html');
});
app.get('/membership/create/form', function(req, res){
res.sendFile(public + 'user/create.html');
});
app.post('/membership/create/submit', function(req, res){
MongoClient.connect(url, function(errdd, db) {
if (errdd) throw errdd;
var dbo = db.db("boaichat");
bcrypt.hash(req.body.password, saltRounds, function(err, hash) {
if (err) {throw err;}
var newUser = { nickname: req.body.nickname, password: hash };
dbo.collection("users").insertOne(newUser, function(errd, ress) {
if (errd) throw errd;
console.log("1 user document inserted");
db.close();
res.send("200 OK");
});
});
});
});
app.get('/membership/login/form', function(req, res) {
res.sendFile(public + 'user/login.html');
});
app.post('membership/login/submit', function(req, res) {
MongoClient.connect(url, function(errdd, db) {
if (errdd) throw errdd;
var dbo = db.db("boaichat");
dbo.collection("users").findOne({nickname: req.body.nickname}, function(err, result) {
if (err) throw err;
if (result) {
bcrypt.compare(req.body.password, result.password, function(err, ress) {
console.log(ress);
res.send(ress);
});
}
});
db.close();
});
});
// IGNORE THIS
app.post('api/v1/getSessionValid', function(req, res) {
let token = req.body.token;
let userInfo = token.split('_._');
if (userInfo[0] && userInfo[1]) {
}
});
io.on('connection', function(socket){
console.log('connection');
socket.on('disconnect', function(){
console.log("disconnection");
});
});
http.listen(3000, function(){
console.log('listening on *:3000');
});

Answer 1

it says 'Cannot post /membership/login/submit'.
Don't forget the / at the beginning of your route.
// Try this
app.post('/membership/login/submit', ...)
// Instead of
app.post('membership/login/submit', ...)
