When a POST request comes in (from a form or ajax request) with these parameters:
``
{
'account':{
username:'adam',
password:'123456',
},
'remain_logged_in': true
}
`
You can check is everything is ok with the submitted data with request.check:
`
var app = new Application(options);

app.get('/login', function(request, response, mysql){
request.demand('account', 'username').length(0,40);
request.demand('account', 'password').length(0,40);
request.demand('remain_logged_in').isBoolean().length(0,1);
if(request.passed){
response.success();
} else {
response.error();
}
});
