Download the PHP package laracrafts/laravel-geo-routes without Composer

GeoLocation Restricted Routes For Laravel

Requirements

• Laravel 5.5 or higher
• PHP 7.1 or higher

Installation

Navigate to your project's root folder via terminal or command prompt and execute the following command:

Note: If you are using package discovery, you can skip the registration of the service provider and the alias as they do register themselves automatically, but don't forget to publish the configuration as described below.

• Register the service provider

Open your config/app.php file and add this entry to the providers array

• Publish the configuration

While still in the same folder, execute this command in your terminal:

Usage

Regular Routes

To get started real quick, the allowFrom and denyFrom methods allow you to restrict access to routes depending on GeoLocations

• Allow access from specific regions

What the above example does, is allowing access to the /home route only from the United States and the United Kingdom.

Alternatively we can do something like the following:

By default, all other countries will receive an HTTP 401 Unauthorized Error, to change this behavior you can use a callback as described in the callbacks section.

• Deny access from specific regions

So in the second example we are going to deny access only from specific locations, for instance: Canada, Germany and France

Alternatively:

Note: This package uses ISO Alpha-2 country codes.

Note: This package uses stevebauman's location package, please refer to it's official documentation for a detailed guide on how to configure it correctly.

Route Groups

Besides allowing you to control access to regular routes, the laravel-geo-routes package also allows you to define route groups and do the same trick with them.

Please consider the following example:

Note: As you may have noticed, we are using the geo method instead of the default group method which will behave the same way the group method does, accepting an array of attributes for the first argument and a routes closure for the second one.

Note: Attributes methods can only be used after calling the geo method so instead of Route::name('english.')->geo(...); you have to write Route::geo(...)->name('english.');

Note: Unless a rule is applied using the from, allow, deny, allowFrom or denyFrom methods the route group will not be defined.

Manual configuration

Under the hood, the allowFrom and the denyFrom methods set the geo attribute on the routes which is an array containing the following parameters:

• [array] countries: The list of countries covered by the geo-constraint.
• [string] strategy: Determines whether to allow or deny access, the value can only be allow or deny.
• [array] callback (optional): The callback that will be invoked once the access is denied and its arguments.

Therefore, if you are more into verbosity, you can define your GeoRoutes in the following way:

Your GeoGroups may also be defined manually as in the following example:

Callbacks

As mentioned earlier, the default behavior for unauthorized users is an HTTP 401 Unauthorized Error response, but you are still able to change this behavior by using callbacks.

To use a callback you have to simply add ->orCallback() to the end of the GeoRoute constraint, like so:

Note: You can also mixin with native router methods

• Default Callbacks

Laravel-geo-routes has some useful built-in callbacks, we are going to list them below along with their use cases.

• orNotFound

The orNotFound callback will result in an HTTP 404 Not Found response for unauthorized visitors.

• orRedirectTo

This callback accepts one required argument which has to be a valid route name. Thanks to this callback, you'll be able to redirect unauthorized visitors to a route of your choice.

• Custom callbacks

  The callbacks above might not be enough for your own use case, so you might want to add custom callbacks, in this guide we will go through several methods to define custom callbacks.

  1. Using a class

  1. Create a new class, for instance CustomCallbacks
  2. Add as many callbacks as you want to add, but be sure that all of your methods are static or you'll be facing problems
  3. Open the config/geo-routes.php configuration file, and add your callbacks to the callbacks array, like so:

Now your callbacks are ready, and you can start using them like so:

Notice that we have added the or prefix and converted the callback name to studly case (e.g. myCallback was converted to orMyCallback), be sure not to forget this note as it is very important for your callback to work.

You may also load these callbacks using the parseCallbacks method of the CallbackRegistrar.

Example:

2. Using an array of callbacks

The loadCallbacks method allows you to load an associative array of callbacks.

Example:

3. Using the callback method

The callback method allows you to add a single custom callback, accepting a name and a callable.

Example:

Artisan Command

We have tweaked the route:list command and added new options in order to make retrieving the geo-constraint information easier. Below you will find the list of new options along with their usage examples.
