htaccess Block all the request if request does not contains specific string patterns

I have a Laravel web site with the localization, for that web site I need to allow the requests with the URL patterns mentioned below. If not match with this URL pattern, need to navigate to the 404 page.

https://www.sampledomain.ch/
https://www.sampledomain.ch/some_text/de
https://www.sampledomain.ch/some_text/it
https://www.sampledomain.ch/some_text/fr
https://www.sampledomain.ch/de
https://www.sampledomain.ch/it
https://www.sampledomain.ch/fr

Can anyone guide me to do this by htaccess file?

Solution

  • 1.) With .htaccess

    Code with comments

    # Run this code IF "mod_rewrite" module was enabled
<IfModule mod_rewrite.c>
    # Enable server-side redirects
    RewriteEngine On

    # If the part after the domain is existed (so not just domain)
    #
    # %{REQUEST_URI}: the part after the domain
    # !^/*$: not empty after "/"
    #
    RewriteCond %{REQUEST_URI} !^/*$
    # AND
    # If the part after the domain not end with de, it, or fr
    #
    # %{REQUEST_URI}: the part after the domain
    # !: not
    # /(de|it|fr): /de or /it or /fr
    # $: need end of url after (de or it or fr)
    # [NC]: treats lowercase and uppercase letters equally
    #
    RewriteCond %{REQUEST_URI} !/(de|it|fr)$ [NC]
    # In that case, it returns a 404 error
    RewriteRule ^ - [R=404,L]
</IfModule>

    Code

    <IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI} !^/*$
    RewriteCond %{REQUEST_URI} !/(de|it|fr)$ [NC]
    RewriteRule ^ - [R=404,L]
</IfModule>

https://www.sampledomain.ch/FR123 # 404 error
https://www.sampledomain.ch/fr/test # 404 error
https://www.sampledomain.ch/a # 404 error

etc.

    2.) Using Laravel Route (better option)

    However, if you are using Laravel, it is worth reconsidering the use of the built-in router as well!

    The example, however, requires that we move the language code to the beginning of the URL, which is generally a common practice.

    1. domain 2. language 3. any other parameters

    Route::get('/{language}/{any}', function ($language, $any) {
    // Handle the request in this function.
    // The $language variable contains the language value,
    // and the $any variable contains any part of the URL.
})->where('any', '.*');

    Your task now is to handle the allowed languages.

    Route::get('/{language}/{any}', function ($language, $any) {
    $allowedLanguages = ['de', 'en', 'fr'];

    if (!in_array(Str::lower($language), $allowedLanguages)) {
        abort(404);
    }

    // If the language is valid, we can continue with the processing.
})->where('any', '.*');
