I am learning how to build a web app using express, node, and angular. I have a post request from angular, and I can successfully send that to the router in login.js:
var user = {username: $scope.userName, password: $scope.password};
$scope.login = function() {
console.log('attempting to log in,,');
console.log("The useranem" + $scope.userName + " " + $scope.password + " " + user);
$http.post('/userLogin', user).then(successCallback, errorCallback);
};
index.js
var express = require('express');
var router = express.Router();
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : 'xxxxx',
database : 'xxxxx'
});
connection.connect();
router.post('/userLogin', function(req, res, next){
console.log('the user name is ' + req.body);
});
module.exports = router;
From the image, I can see that I was able to print out the body of the post request as objects. Is this because I don't have body parser in index.js. I already installed body parser in app.js,
1) do I have to require app.js in index.js to use the body parser?
2)And once I am able to parse the body, how do I access the varaibles in the body. Would it be req.username and req.password?
3) This question is not as related, but in my app.js I have app.use('/', login). How do i determine what the path should be? Should it be the same as the express router such as /userLogin?
This is my app.js:
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mysql = require('mysql');
var routes = require('./routes/index');
var register = require('./routes/register');
var users = require('./routes/users');
var login = require('./routes/login');
var app = express();
//establish database connection
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : 'xxxxx',
database : 'xxxxx'
});
connection.connect();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
app.use('/', login);
//add route for registering account
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
Note: most of the stuff in app.js was created using express generator.
