CodeIgniter 3 + XAMPP 环境下无法移除URL中的index.php求助

Hey, I see you've already dug through several posts and tried basic configurations, but that 404 error when skipping index.php is a common snag with subdirectory deployments. Let's work through the fixes one by one:

• Update Your base_url Configuration
  Your current $config['base_url'] points to http://localhost, but your site lives in the /mysite subdirectory. This misalignment throws off CodeIgniter's routing logic. Update it to:

  $config['base_url'] = "http://localhost/mysite/";
  

• Adjust .htaccess with RewriteBase
  Apache needs explicit guidance on the base directory for rewrite rules when working in a subfolder. Modify your .htaccess file (make sure it’s placed in the same folder as CodeIgniter’s index.php) to include RewriteBase and tweak the final rule:

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

  The key changes here are adding RewriteBase /mysite/ and removing the ? in the RewriteRule—CodeIgniter doesn’t require that query string format for routing.

• Verify .htaccess Location
  Double-check that your .htaccess file is placed directly in htdocs/mysite/ (the same directory as index.php). If it’s in the root htdocs folder or another location, the rewrite rules won’t apply to your site.

• Enable AllowOverride in Apache's httpd.conf
  You’ve turned on the rewrite module, but Apache might still be blocking .htaccess rules in your subdirectory. Open httpd.conf and find the <Directory> block for your site’s folder (or the root htdocs folder). Change AllowOverride None to AllowOverride All:

  <Directory "C:/xampp/htdocs/mysite">
      AllowOverride All
      Require all granted
  </Directory>
  

  Don’t forget to restart Apache after making this change—the configuration won’t take effect until you do.

• Try a Different uri_protocol
  Your current setting REQUEST_URI works for most environments, but switching to AUTO can help CodeIgniter correctly parse the URL in some cases. Update config.php:

  $config['uri_protocol'] = 'AUTO';
  

• Confirm mod_rewrite is Actually Enabled
  To be 100% sure the rewrite module is active, create a file named info.php in your mysite folder with this content:

  <?php phpinfo(); ?>
  

  Visit http://localhost/mysite/info.php and search for "mod_rewrite". If it doesn’t show up, go back to httpd.conf and confirm the line LoadModule rewrite_module modules/mod_rewrite.so is uncommented, then restart Apache again.

After making all these changes and restarting Apache, test accessing http://localhost/mysite/newpage—it should load without needing index.php now.
