App.post () doesn't work with Express

I have a problem with Express, I am trying to use the app.post () function, but it doesn’t work and I don’t know why ...

Although I've included bodyParser () ...

Problem: Page load with no response, no error message. I can't see console.log () ...

app.js:

var express = require('express')
    , routes = require('./routes')
    , user = require('./routes/user')
    , postProvider = require('./postProvider.js')
    , http = require('http')
    , path = require('path')
    , compass = require('node-compass')
    , hash = require('./auth').hash;

var app = express();

app.configure(function () {
    app.set('port', process.env.PORT || 3000);
    app.set('views', __dirname + '/views');
    app.set('view engine', 'jade');
    app.use(compass());
    app.use(express.favicon());
    app.use(express.logger('dev'));
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(app.router);
    app.use(express.static(path.join(__dirname, 'public')));
    app.use(express.cookieParser('dsqdq edsds'));
    app.use(express.session());
});

app.configure('development', function () {
    app.use(express.errorHandler());
});

app.get('/admin', function(req, res){
    res.redirect('login');
});

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

app.post('/login', function(req, res){
    console.log('test');
});

app.get('/', routes.index);

http.createServer(app).listen(app.get('port'), function () {
    console.log("Express server listening on port " + app.get('port'));
});

login.jade:

extends layout

block content
  h1 Login
  h3 "tj" and "foobar"
  form(method="post", action="/login")
    input(type="text", placeholder="Username", autofocus="true", name="username")
    br
    input(type="password", placeholder="Password", name="password")
    br
    input(type="submit", value="login")

I see no problem with the app.post code!

app.post('/login', function(req, res){
    console.log('test');
    res.end(); // end the response
});


One suggestion is that you must stop sending every response to the client, otherwise your server will stop responding to requests.

Your post request is sent to /test

(since you used action

your form attribute ), while your express listener listens for any post requests to /login

.

Your code should look like this:



block content
  h1 Login
  h3 "tj" and "foobar"
  form(method="post", action="/login")

If you want this to work!

I copy 'router.post () ...' to another js file and change the route in app.js, it works! But the router.post () method is still a warning. Sometimes it looks like a warning in webstorm, but it might work!

While I didn't go through all the code mentioned here, I encountered a similar problem and was able to debug it.

I will share where I went wrong and maybe it can help someone.

Below is the HTML code that is out of order:

<form action="/" method="**post**">

    <select name="crypto">
        <option value="BTC">Bitcoin</option>
        <option value="ETC">Ethereum</option>
        <option value="LTC">Litecoin</option>
    </select>

    <select name="fiat">
        <option value="USD">US Dollors</option>
        <option value="GBP">GB Pounds</option>
        <option value="EUR">EU Euros</option>
    </select>

</form>

Check

The error is in this code, although (type) is "submit", it was not included in the tag. Now when you use the "app.post" method to get data or try to tell "console.log (value)" to a requirement, it cannot access it.

I was able to debug by including the button tag inside the form.
