当我调用控制器时，代码点火器无法识别我的base-url [重复]

My app recognizes main page index.php (that calls a controller which name is Home and shows this Home page, as expected).

Although when I call a topic in the menu (which is also a controller), it fails with this error:

HTTP Error 404.0 - Not Found

http://alfa.teste:80/estrutura where

http://alfa.teste/ is the base url and 'estrutura' is the controller.

Please, any help? Thank you so much!

in config.php file put this small code bellow base_url array

$config['base_url'] = ' ';

//try to catch the base url in case of undefined base url 
if (!$config['base_url']) {

    $domain = $_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME'];

    $domain = preg_replace('/index.php.*/', '', $domain);
    if (!empty($_SERVER['HTTPS'])) {
        $config['base_url'] = 'https://' . $domain;
    } else {
        $config['base_url'] = 'http://' . $domain;
    }
}

and in autoload.php file you need to add url in helper array like this:

$autoload['helper'] = array('url');

Your code will work fine if you call base url function

base_url();

If this still not works for you then you need to create an .htaccess file in root folder of the project. write the following code in .htaccess file:

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [QSA,L]

I hope any of the above solution will work for you.
