Codeigniter routing throws 404 page not found error - php

Question

When I am using url as
mysite.com/index.php/user/user the method is getting called.
But when I add below line in routes.php so that I can access the function using custom url.
it is throwing me error. 404 Not Found
I want to access the method using url as mysite.com/user
$route['user']['get'] = 'user/user';
user.php is present inside controller directory
<?php
use Restserver\Libraries\REST_Controller;
defined('BASEPATH') OR exit('No direct script access allowed');
require APPPATH . 'libraries/REST_Controller.php';
require APPPATH . 'libraries/Format.php';
class User extends REST_Controller {
function __construct()
{
// Construct the parent class
parent::__construct();
}
public function user_get(){
$this->set_response("request recieved", REST_Controller::HTTP_OK); // OK (200) being the HTTP response code
}
}
[2nd question]
how to make a route to access the controller present inside certain folders in controller directory.
suppose a controller file is present in controllers/api/v1/ directory with file name user.php
Note:
I have tried all the solutions given by users on other posts but issue was not resolved.
EDIT: Issue Resloved
Routing is working just fine now. I think the problem was, I was calling mysite.com/user , instead I should have called mysite.com/index.php/user
Second issue of index.php being in the url is also resolved.
I was making the changes in .htaccess file which was present in Application folder instead.
I created a .htaccess file in root folder then added below mentioned line of code
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

You have set your route as
$route['user']['get'] = 'user/user';
Which is directing to the user controller and the user method. But in your controller you have a method called user_get.
So the simplest fix here is to change your route to point to the correct method.
NOTE: You have no method called 'user' so why is that in the route?
So this...
$route['user']['get'] = 'user/user'; // the user method does not exist
Would become...
$route['user']['get'] = 'user/user_get'; // the user_get method does exist
Update: To remove index.php from your URL, your .htaccess might be
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
And make sure you add in your base_url in applications/config/config.php
$config['base_url'] = 'http://example.com'; // Change to your sites URL
$config['index_page'] = ''; // remove index.php
